In this chapter...  
This Installation and User’s Guide explains how to install your Adaptec® Serial Attached SCSI  
controller. It also describes the utilities included in your controller kit, and provides a basic  
overview of Serial Attached SCSI (SAS) technology.  
These HostRAID controller models are described in this Guide:  
Adaptec SAS 58300, see page 14  
Adaptec SAS 48300, see page 15  
Adaptec SAS 44300, see page 16  
   
Chapter 1: About This Guide  
11  
What You Need to Know Before You Begin  
You should be familiar with computer hardware, data storage, Redundant Array of  
Independent Disks (RAID) technology, and the input/output (I/O) technology—SAS—used  
by your HostRAID controller. (For an introduction to SAS, see page 52.)  
You should also be familiar with Direct Attached Storage (DAS) and Storage Area Network  
(SAN) concepts and technology.  
Terminology Used in this Guide  
Because you can use your HostRAID controller to manage data storage in a variety of  
configurations from DAS to SAN, the generic term “storage space” is used to refer to  
controller(s) and disk drives being managed with Adaptec Storage ManagerTM or the other  
utilities described in this Guide.  
Many of the terms and concepts referred to in this Guide are known to computer users by  
multiple names. This Guide uses these terms:  
Controller (also known as adapter, board, or card)  
Disk drive (also known as hard disk, hard drive, or hard disk drive)  
Array (also known as a container or logical drive)  
Note: The Adaptec Storage Manager User’s Guide refers to arrays as logical drives. Why?  
Your HostRAID controller creates arrays, which your operating system (and Adaptec Storage  
Manager) recognizes as logical drives.  
How to Find More Information  
You can find more information about your HostRAID controller and the software and utilities  
included with it by referring to these documents:

In this chapter...  
This chapter provides the basic information you need to set up your disk drives and arrays the  
way you want them. It also describes the options you have for installing your HostRAID  
controller and disk drives, and creating arrays for data storage.  
Note: Before you begin, familiarize yourself with your HostRAID controllers physical  
features and the RAID levels that it supports (see page 12).  
 
Chapter 4: Getting Started  
20  
Choosing a RAID Level  
This section provides a brief overview of thReAID levels supported by your HostRAID  
controller including the minimum and maximum number of disk drives required by each  
RAID 0 (Non-redundant Array)—Stripes data across multiple disk drives. Improved  
performance but no redundancy (see page 60).  
RAID 1 Array—Created from two disk drives where one disk drive is a mirror of the other (the  
same data is stored on each disk drive). Redundancy, but reduced capacity (see page 61).  
RAID 10 Array—Built from two or more equal-sized RAID 1 arrays, stripes and mirrors data  
across multiple disk drives. Redundancy and improved performance (see page 61).  
Use the table on page 60

that it supports (see page 12).  
Ensure that you have the right quantity of disk drives for the RAID level you want to use  
for your arrays (see page 58).  
Ensure that you have the proper cables for your controller and disk drives (see page 12).  
If you have a low-profile computer cabinet, replace the original full-height bracket with the  
low-profile bracket supplied in the controller kit.  
Caution: Handle the controller by its bracket or edges only.  
!
Installing the HostRAID Controller  
This section describes how to install your HostRAID controller into your computer cabinet.  
1
Turn off your computer and disconnect the power cord. Open the cabinet, following the  
manufacturer’s instructions.  
2
Select an available PCI or PCI-X expansion slot and remove  
the slot cover, as shown at right. (see page 12.)  
For the best performance, use the available 64-bit slot that’s  
compatible with your HostRAID controller.  
Caution: Touch a grounded metal object before  
handling the HostRAID controller.  
!
3
As shown at right, insert the HostRAID controller into the  
PCI or PCI-X expansion slot and press down gently but  
firmly until it clicks into place. When installed properly, the  
HostRAID controller should appear level with the  
expansion slot.

Secure the bracket in the PCI slot, using the retention  
device (for instance, a screw or lever) supplied with your  
computer.  
Connect your computer’s disk activity LED cable to the  
LED connector on the controller (see page 12).  
Ensure that the positive lead of the LED cable (usually a red  
wire or a wire marked with a red stripe) is attached to pin 1.  
6
7
Optional—Connect your HostRAID controller’s I2C  
connector (not available on all models) to an I2C  
connector on an internal backplane or enclosure, using an  
I2C cable.  
Install your disk drives, following the instructions on page 25.  
     
Chapter 5: Installing the HostRAID Controller and Disk Drives  
25  
Connecting Disk Drives to HostRAID Controllers  
You can connect SAS disk drives, SATA disk drives, or a combination of both to your  
HostRAID controller. There are no jumpers or switches to set before installation.  
If you plan to build a bootable array using internal disk drives, ensure you install at least the  
minimum number disk drives required to support the RAID level you want. See page 58 for  
more information.  
Note: Although you can connect both SAS and SATA disk drives to your SAS controller,  
Adaptec recommends that you not combine SAS and SATA disk drives within the same  
array or logical drive. See page 55 for more information.  
You have two connection options:  
To connect directly to the controller, see page 25.  
To connect to a backplane, see page 26.  
Connecting Directly to the HostRAID Controller  
In a direct-attach connection, SAS or SATA disk drives are connected directly to a SAS card  
with SAS cables.The number of direct-attached disk drives is limited to four per internal SAS  
connector. (For more information about direct-attach connections, see page 56.)  
1 Install your internal SAS or SATA disk drives, following the instructions in your system’s  
documentation.  
2 Use internal SAS cables to attach the disk drives to the controller.

Connecting to a System Backplane  
In a backplane connection, disk drives and SAS cards are attached to and communicate with  
each other through a system backplane.  
The number of disk drives is limited to the number of slots available on the backplane. Some  
backplanes have embedded SAS expanders and can support up to 128 end devices. (For more  
information about backplane and expander connections, see page 27.)  
1 Connect one or more internal SAS or SATA disk drives to the backplane. (Refer to your  
system’s documentation for more information.)  
2 Use an internal SAS cable to connect the controller to the backplane.

Chapter 5: Installing the HostRAID Controller and Disk Drives  
27  
Installing the Controller to a SAS Expander  
You can use a SAS edge expander to connect multiple disk drives to your HostRAID controller  
or multiple controllers. Commands can be sent down one link and data returned on another in  
a separate connection to increase fault tolerance. Using a SAS expander and dual-port SAS  
drives and SATA drives with 2-port adapters, you can design redundant systems for maximum  
fault-tolerance.  
To install the HostRAID controller to a SAS expander:  
1 Using the appropriate cable, connect the HostRAID controller to a PHY connector on the  
expander.  
2 Connect a cable from a PHYconnector on the expander to a disk drive.

About Adaptec Storage Manager  
Adaptec Storage Manager is a full-featured software application that helps you build a storage  
space for your online data, using HostRAID controllers and disk drives.  
With Adaptec Storage Manager, you can group disk drives into logical drives and build in  
redundancy to protect your data and improve system performance.  
You can also use Adaptec Storage Manager to monitor and manage all the controllers and disk  
drives in your storage space from a single location.  
When Adaptec Storage Manager is installed on a computer, the Adaptec Storage Manager agent  
is also installed automatically. The agent is like a service that keeps your storage space running.  
It’s designed to run in the background, without user intervention, and its job is to monitor and  
manage system health, event notifications, tasks schedules, and other on-going processes on  
that system. It sends notices when tasks are completed successfully, and sounds an alarm when  
errors or failures occur on that system.  
The agent uses less memory than the full application. If your storage space includes systems  
that won’t be connected to monitors (and therefore won’t require the user interface), you can  
choose to run the agent only on those systems instead of the full application. For more  
information, refer to the Adaptec Storage Manager User’s Guide or online Help.  
Installing Adaptec Storage Manager  
Adaptec Storage Manager is included on the Adaptec Storage Manager Installation CD. For  
installation instructions, refer to the Adaptec Storage Manager User’s Guide, also included on  
the Adaptec Storage Manager Installation CD.  
About the HRCONF Command Line Utility  
HRCONF (HostRAID Configuration Utility) is a command line utility that you can use to  
perform some basic array and configuration management functions.  
With HRCONF, you can:  
Create and delete logical drives  
Modify and copy configuration settings  
Recover from disk drive failures and troubleshoot  
Installing and Using the Command Line Utility on page 76, describes how to use HRCONF.  
Note: Adaptec recommends that only advanced users familiar with command line  
interfaces use HRCONF.

About the ARC Utility  
The Adaptec RAID Configuration (ARC) utility is a BIOS-based utility that you can use to  
create and manage controllers, disk drives and other devices, and arrays. The ARC utility  
comprises these tools:  
Array Configuration Utility (ACU)—For creating and managing arrays, and initializing  
and rescanning disk drives.  
SerialSelect Utility—Used to change device and HostRAID controller settings.  
Disk Utilities—For formatting or verifying disk drives.  
The ARC utility is included in your controller’s BIOS. For more information, see Using the  
Note: The ARC utility is primarily intended for pre-operating system installation  
configuration.  
About the AFU  
The Adaptec Flash Utility (AFU) is a text-based DOS utility that you can use to update, save, or  
verify your HostRAID controller’s firmware BIOS and Non-Volatile Random Access Memory  
(NVRAM).  
Caution: Although the AFU contains safeguards to prevent you from accidentally damaging  
your HostRAID controllers flash contents, it is still important to use the AFU carefully and  
!
correctly to avoid rendering your HostRAID controller inoperable. Adaptec recommends that  
only advanced users familiar with working in DOS use the AFU.  
Which Utility Should I Use?  
To create a bootable array, Adaptec recommends that you use the BIOS-based ARC utility  
(see above).  
For all subsequent storage management tasks, Adaptec recommends that you install and use  
Adaptec Storage Manager (see page 42). As a full-featured software application with a graphical  
user interface (GUI), it is the easiest to use and offers the widest range of management  
functions.

Physical Devices View  
This view displays information about the drives, enclosures, and other physical devices  
attached to the controller. The devices are organized numerically. The display for each channel  
or port includes information on maximum speed, the number of the channels on the  
controller, and the number of devices attached to the controller.  
Indicators, next to the controller name, report status of the fan and temperature modules on  
SAF-TE (enclosure management) devices and other devices that monitor these conditions. The  
indicator colors are:  
Blue—Normal  
YellowWarning  
Red—Error  
Gray—Not applicable to the devices.  
For example, the fan indicator changes to yellow when one fan fails; it changes to red when a  
second fan fails and cooling is no longer adequate.  
Logical Devices View  
This view displays information about the logical devices created using the physical devices,  
including the number of logical devices, the RAID level of each device, and whether a logical  
device is protected by a hot spare.  
You can create and delete logical devices in the Logical devices view by selecting the Create  
option and using the Create wizard.

This chapter provides basic troubleshooting information and solutions for solving your  
HostRAID controller problems.  
 
Chapter 11: Solving Problems  
50  
Troubleshooting Checklist  
If you encounter difficulties installing or using your HostRAID controller, check these items  
first:  
With your computer powered off, check the connections to each disk drive, the power  
supply, the LED connector, and so on.  
Try disconnecting and reconnecting disk drives from the HostRAID controller.  
Check that your HostRAID controller is installed in a compatible expansion slot (PCI-X).  
To double-check the bus compatibility of your controller, see About Your HostRAID  
Ensure that your HostRAID controller is firmly seated and secured in the PCI-X expansion  
slot.  
If your HostRAID controller is not detected during system boot, try installing it in a  
different PCI-X expansion slot. (See page 24 for instructions.)  
Did the driver install correctly?  
If you are still unable to resolve a problem, you can find additional troubleshooting  
information and direction on the Adaptec Web site at www.adaptec.com and the Adaptec  
Support Knowledgebase at ask.adaptec.com.  
Recovering from a Disk Drive Failure  
This section explains how to recover when a disk drive fails:  
If the array was protected by a hot spare (see next section).  
If the array was not protected by a hot spare (see page 51).  
If there is a disk drive failure in more than one array simultaneously (see page 51).  
If it is a RAID 0 array (see page 51).  
If multiple disk drives fail within the same array (see page 51).  
Note: Adaptec Storage Manager uses the term logical drives when referring to arrays  
(see page 11).  
Failed Disk Drive Protected by a Hot Spare  
When an array is protected by a hot spare, if a disk drive in that array fails the hot spare is  
automatically incorporated into the array and takes over for the failed drive.  
To recover from the failure:  
Remove and replace the failed disk drive (following manufacturer’s instructions).  
         
Chapter 11: Solving Problems  
51  
Failed Disk Drive Not Protected by a Hot Spare  
When an array is not protected by a hot spare, if a disk drive in that array fails, remove and  
replace the failed disk drive. The controller detects the new disk drive and begins to rebuild the  
array.  
If the controller fails to rebuild the array, check that the cables, disk drives, and controllers are  
properly installed and connected. Then, if necessary, use Adaptec Storage Manager to rebuild  
the array. For instructions, refer to the Adaptec Storage Manager User’s Guide or online Help.  
Failure in Multiple Arrays Simultaneously  
If there’s a disk drive failure in more than one array at the same time (one failure per array),  
and the arrays have hot spares protecting them, the controller rebuilds the arrays with these  
limitations:  
A hot spare must be of equal or greater size than the failed disk drive it’s replacing.  
Failed disk drives are replaced with hot spares in the order in which they failed. (The array  
that includes the disk drive that failed first is rebuilt first, assuming an appropriate hot  
spare is available—see bullet above.)  
If there are more disk drive failures than hot spares, see Failed Disk Drive Not Protected by a Hot  
Spare in previous section.  
Disk Drive Failure in a RAID 0 Array  
Because RAID 0 volumes do not include redundancy, if a disk drive fails in a RAID 0 array, the  
data can’t be recovered.  
Correct the cause of the failure or replace the failed disk drives. Then, restore your data (if  
available).  
Multiple Failures in the Same Array  
If more than one disk drive fails at the same time in the same RAID 1 array, the data can’t be  
recovered.  
Correct the cause of the failure or replace the failed disk drives. Then, restore your data (if  
available).  
In some instances, RAID 10 arrays may survive multiple disk drive failures, depending on  
which disk drives fail. For more information, refer to the Adaptec Storage Manager User’s Guide  
or online Help.  
             
Introduction to SAS  
A
In this chapter...  
This section provides a basic overview of the main features of SAS, introduces some common  
SAS terms, and explains how SAS differs from parallel SCSI.  
Note: For technical articles and tutorials about SAS, refer to the SCSI Trade Association  
(STATM) Web site at www.scsita.org  
.
   
Appendix A: Introduction to SAS  
53  
Terminology Used in This Chapter  
For convenience, SAS HostRAID controllers are referred to generically in this chapter as SAS  
cards. HBAs, HostRAID controllers, disk drives, and external disk drive enclosures are referred  
to as end devices and expanders are referred to as expander devices.  
For convenience, this chapter refers to end devices and expander devices collectively as SAS  
devices.  
What is SAS?  
Legacy parallel SCSI is an interface that lets devices such as computers and disk drives  
communicate with each other. Parallel SCSI moves multiple bits of data in parallel (at the same  
time), using the SCSI command set.  
SAS is an evolution of parallel SCSI to a point-to-point serial interface. SAS also uses the SCSI  
command set, but moves multiple bits of data one at a time. SAS links end devices through  
direct-attach connections, or through expander devices.  
SAS cards can typically support up to 128 end devices and can communicate with both SAS  
and SATA devices. (You can add 128 end devices—or even more—with the use of SAS  
expanders. See page 56.)  
Although you can use both SAS and SATA disk drives in the same SAS domain (see page 56),  
Adaptec recommends that you not combine SAS and SATA disk drives within the same array or  
logical drive. The difference in performance between the two types of disk drives may adversely  
affect the performance of the array.  
Data can move in both directions simultaneously across a SAS connection (called a link—see  
next section). Link speed is 600 MB/sec in full-duplex mode. A SAS card with eight links has a  
maximum bandwidth of 4800 MB/sec in full-duplex mode.  
Although they share the SCSI command set, SAS is conceptually different from parallel SCSI  
physically, and has its own types of connectors, cables, connection options, and terminology, as  
described in the rest of this chapter.  
To compare SAS to parallel SCSI, see How is SAS Different from Parallel SCSI? on page 57.  
How Do SAS Devices Communicate?  
SAS devices communicate with each other through links. A link is a physical connection  
between two phys.  
                     
Appendix A: Introduction to SAS  
54  
As shown in the following figure, SAS devices contain ports which contain phys (see next  
section), and each phy contains one transmitter and one receiver—one transceiver. A phy can  
belong to one port only.

What’s a Phy?  
Phys are part of the physical communication connection between SAS devices. Each phy  
contains a transceiver that sends data back and forth between SAS devices.  
When a connection is formed between two end devices, a link is established from a phy in one  
port to a phy in the other port. As shown in the figure above, a wide port can support multiple  
independent links simultaneously.  
Phys are internal, within SAS connectors (see page 55).  
SAS cables physically connect one or more phys on one SAS device to one or more phys on  
another SAS device.  
What’s a SAS Port?  
Note: Because the physical link between SAS devices is from phy to phy, rather than port  
to port, a “port” is more of a virtual concept, different from what is normally considered a  
port on other types of RAID controllers and storage devices.  
A port is one or more phys. A narrow port contains one phy. A wide port typically contains four  
phys.  
Each port has its own unique SAS address (see page 55), and all the phys in a port share that  
same SAS address.  
SAS card port options vary. A SAS card with four phys could be configured with one wide port,  
with two wide ports that comprise two phys, or with four narrow ports each containing one  
phy. (A wide port with four phys is referred to as a 4-wide or 4x port.)  
             
Appendix A: Introduction to SAS  
55  
What’s a SAS Address?  
Each SAS port is identified with a unique SAS address, which is shared by all phys on that port.  
For example, a SAS disk drive might have two narrow ports. Each port has one unique SAS  
address. The single phy in each port uses its port’s SAS address.  
In another example, a SAS device might have one 4-wide port. That port has one SAS address,  
which is shared by all four phys in the port.  
Unlike SCSI devices and SCSI IDs, SAS devices self-configure their SAS addresses. User  
intervention is not required to set SAS addresses, and SAS addresses cannot be modified.  
What’s a SAS Connector?  
A SAS connector is the physical plug or receptacle that you see on a SAS device. It supports the  
power and signal line cable. It’s what you plug a SAS cable into, or the end of the SAS cable  
that’s being plugged in.  
A connector is what forms physical links between phys. Some SAS connectors can support  
multiple links. The number of links a SAS connector can support is referred to as its width.  
Narrow connectors support a single link; wide connectors support up to four links.  
A single SAS device may have one or more connectors. A single SAS connector may help form  
links between more than two SAS devices. (For instance, as shown in the figure on page 54, the  
4-wide internal SAS connector forms links with four independent disk drives.)  
What do SAS Cables Look Like?  
Internal SAS cables are narrower than internal parallel SCSI cables. The connectors vary in size  
depending on the number of links they support, from single link connectors to 4-wide (or  
larger) connectors. Internal fan-out cables let you attach four disk drives to a single 4-wide  
connector.  
For an example of some internal SAS cables and an external SAS cable, see Selecting Cables on  
How are Disk Drives Identified in SAS?  
In the BIOS and in the management utilities (see page 69), disk drives are identified with  
numbers in this format:  
XX:YY:ZZ  
where XX is the disk drive count number, YY is the enclosure number, and ZZ is the slot  
number (within the enclosure). If the disk drive is not installed in an enclosure, a double  
dashes (--) appear instead of YY and ZZ (for instance, 01:--:--).  
In parallel SCSI, XX is the disk drive’s channel number, YY is the target number, and ZZ is the  
logical unit number (LUN).  
What are the SAS Connection Options?  
You can connect end devices to each other through direct cable connections and through  
backplane connections. When you use one or more expander devices (see page 56), you can  
create large configurations.  
                       
Appendix A: Introduction to SAS  
56  
Direct-attach Connections  
In a direct-attach connection, SAS or SATA disk drives are connected directly to a SAS card  
with SAS cables. One disk drive is attached to one SAS connector with one SAS cable (or  
multiple disk drives are attached to one SAS connector with one fan-out cable). The figure on  
page 25 shows an example of direct-attach connections.  
The number of direct-attached disk drives is limited to the number of phys supported by the  
SAS card. (Note that there may be multiple phys within a single connector. See page 55.)  
Backplane Connections  
In a backplane connection, disk drives and SAS cards are attached to and communicate with  
each other through a system backplane. The figure on page 26 shows an example of backplane  
connections.  
The number of end devices is limited to the number of slots available on the backplane. For  
example, the Adaptec S50 enclosure, which contains an expander, is a backplane connection  
that supports up to 12 SAS or SATA disk drives.  
Some backplanes support daisy-chain expansion to other backplanes. For example, you can  
daisy-chain (connect one to the next) up to nine Adaptec S50 enclosures to a single SAS card in  
a host system.  
SAS Expander Connections  
A SAS expander device literally expands the number of end devices that you can connect  
together. Expander devices, typically embedded into a system backplane (see page 26), support  
large configurations of SAS end devices, including SAS cards and SAS and SATA disk drives.  
With expander devices, you can build large and complex storage topologies.  
There are two types of SAS expanders: fanout expanders and edge expanders. Each performs a  
different role in a storage system. (For more information about how SAS expanders work, refer  
to the STA Web site at www.scsita.org.)  
You can connect up to 128 SAS ports to an edge expander. (A single edge expander can  
therefore support up to 128 SAS addresses.)  
You can connect up to 128 edge expanders to a fanout expander.  
You can use only one fanout expander in any single SAS domain (a topology of SAS—and  
possibly SATA—end devices and expander devices). A single SAS domain can therefore  
comprise up to 16,384 SAS ports (and therefore up to 16,384 SAS addresses).  
                     
Appendix A: Introduction to SAS

How is SAS Different from Parallel SCSI?  
In summary, although SAS and parallel SCSI both use the SCSI command set, how they move  
data from one place to another is very different. To support point-to-point serial data  
transport, SAS introduces new types of connectors, cables, connection options, and  
terminology.  
Generally speaking, SAS is faster and more flexible than parallel SCSI, and provides more  
options for building your storage space. SAS lets you mix SAS and SATA disk drives together,  
and lets you connect many, many more devices.  
The following table describes many of the main differences between the two interfaces.

Understanding RAID  
B
In this chapter...  
When you create arrays (or logical drives), you can assign a RAID level to protect your data.  
Each RAID level offers a unique combination of performance and redundancy. RAID levels  
also vary by the number of disk drives they support.  
This appendix describes the RAID levels supported by your HostRAID controller, and provides  
a basic overview of each to help you select the best level of protection for your data storage.  
   
Appendix B: Understanding RAID  
59  
RAID Technology Overview  
RAID is the technology of grouping several physical drives in a computer into an array that you  
can define as one or more logical drives. Each logical drive appears to the operating system as a  
single drive. This grouping technique greatly enhances logical-drive capacity and performance  
beyond the physical limitations of a single physical drive.  
When you group multiple physical drives into a logical drive, the HostRAID controller can  
transfer data in parallel from the multiple drives in the array. This parallel transfer yields data-  
transfer rates that are many times higher than with non-arrayed drives, enabling the system to  
better meet the throughput (amount of data processed in a given amount of time) or  
productivity needs of the multiple-user network environment.  
The ability to respond to multiple data requests provides not only an increase in throughput,  
but also a decrease in response time. The combination of parallel transfers and simultaneous  
responses to multiple requests enables disk arrays to provide a high level of performance in  
network environments.  
Understanding Drive Segments  
A drive segment is a disk drive or portion of a disk drive that is used to create an array. A disk  
drive can include both RAID segments (segments that are part of an array) and available  
segments. Each segment can be part of only one logical device at a time. If a disk drive is not  
part of any logical device, the entire disk is an available segment.  
Stripe-unit Size  
With RAID technology, data is striped across an array of physical drives. This data-distribution  
scheme complements the way the operating system requests data.  
The granularity at which data is stored on one drive of the array before subsequent data is  
stored on the next drive of the array is called the stripe-unit size.  
You can set the stripe-unit size to 16, 32, or 64 KB. You can maximize the performance of your  
HostRAID controller by setting the stripe-unit size to a value that is close to the size of the  
system I/O requests. For example, performance in transaction-based environments, which  
typically involve large blocks of data, might be optimal when the stripe-unit size is set to 32 or  
64 KB. However, performance in file and print environments, which typically involve multiple  
small blocks of data, might be optimal when the stripe-unit size is set to 16 KB.  
The collection of stripe units, from the first drive of the array to the last drive of the array, is  
called a stripe.  
Selecting a RAID Level and Tuning Performance  
Disk arrays are used to improve performance and reliability. The amount of improvement  
depends on the application programs that you run on the server and the RAID levels that you  
assign to the logical drives.  
Each RAID level provides different levels of fault-tolerance (data redundancy), utilization of  
physical drive capacity, and read and write performance. In addition, the RAID levels differ in  
regard to the minimum and maximum number of physical drives that are supported.

When selecting a RAID level for your system, consider the following factors.

Physical drive utilization, read performance, and write performance depend on the number of  
drives in the array. Generally, the more drives in the array, the better the performance.  
RAID 0 (Non-RAID Arrays)  
An array with RAID 0 includes two or more disk drives (maximum twelve) and provides data  
striping, where data is distributed evenly across the disk drives in equal-sized sections.  
RAID 0 arrays do not maintain redundant data, so they offer no data protection. However,  
compared to an equal-sized group of independent disks, a RAID 0 array provides improved  
I/O performance.  
Drive segment size is limited to the size of the smallest disk drive in the array. For instance, an  
array with two 250 GB disk drives and two 400 GB disk drives can create a RAID 0 drive  
segment of 250 GB, for a total of 1000 GB for the volume, as shown in the following figure.

RAID 1 Arrays  
A RAID 1 array is built from two disk drives, where one disk drive is a mirror of the other (the  
same data is stored on each disk drive). Compared to independent disk drives, RAID 1 arrays  
provide improved performance, with twice the read rate and an equal write rate of single disks.  
However, capacity is only 50 percent of independent disk drives.  
If the RAID 1 array is built from different-sized disk drives, the free space, drive segment size is  
the size of the smaller disk drive, as shown in the following figure.

RAID 10 Arrays  
A RAID 10 array is built from two or more equal-sized RAID 1 arrays. Adaptec RAID  
controllers support a maximum number of 48 disk drives in a RAID 10 array.  
Data in a RAID 10 array is both striped and mirrored. Mirroring provides data protection, and  
striping improves performance.  
Drive segment size is limited to the size of the smallest disk drive in the array. For instance, an  
array with two 250 GB disk drives and two 400 GB disk drives can create two mirrored drive  
segments of 250 GB, for a total of 500 GB for the array, as shown in the following figure.

Appendix C: Using the ARC Utility  
63  
Introduction to the ARC Utility  
The ARC utility comprises these tools:  
The Array Configuration Utility (ACU)—Used to create, configure, and manage arrays,  
and initialize and rescan disk drives.  
SerialSelect Utility—Used to change device and HostRAID controller settings.  
Disk Utilities—Used to format or verify disk drives (see page 69).  
Running the ARC Utility  
All the tools within the ARC utility are menu-based and instructions for completing tasks  
display on-screen. Menus can be navigated using the arrows, Enter, Esc, and other keys on  
your keyboard.  
To run the Utility:  
1
Start or restart your computer. When prompted, press Ctrl+A.  
The ARC utility menu displays presenting these options:  
Array Configuration Utility (ACU)  
SerialSelect Utility  
Disk utilities  
To select an option from this menu, or from any of the menus within the ARC utility setup,  
browse with the arrow keys, then press Enter. In some cases, selecting an options displays  
another menu. To return to the previous menu at any time, press Esc.  
Creating and Managing Arrays  
Before creating arrays, make sure the disks for the array are connected and installed in your  
system. Note that disks with no usable space are shown in gray and cannot be used.  
Creating a New Array  
To create an array:  
1
Select Create Array from the main ACU menu.  
Note: For more information about RAID levels and using disk drives to create arrays, see  
2
3
Select the disks for the new array, then press Insert. To deselect any disk, highlight the disk,  
then press Delete.  
Press Enter when all disks for the new array are selected. The Array Properties menu  
displays.  
Assigning Array Properties  
Once the array is created and its properties are assigned, you cannot change the array  
properties using the ACU. Instead, use Adaptec Storage Manager (See Chapter 10, for details.)  
                     
Appendix C: Using the ARC Utility  
64  
To assign properties to the new array:  
1
In the Array Properties menu, select an array type, then press Enter.  
Only the available array types, RAID 0, 1, and 10 are displayed. RAID 0 and 1 requires two  
to four drives. RAID 10 requires a minimum of four disk drives.  
2
3
Optional: Type a label of no more than 15 characters for the array, then press Enter.  
For RAID 0, select the desired stripe size. Available stripe sizes are 16, 32, and 64 KB  
(default).  
Note: It is recommended that you do not change the default.  
4
The options under Create RAID Via allows you to select between the different creation  
methods for RAID 0, 1, and 10. The following table gives examples of when each is  
appropriate.

Creating a RAID 1 and you want to preserve data on an existing  
drive. You will be asked to select the source drive. The contents  
of the source drive are preserved and any data on the new drive  
is lost.  
RAID 1,

Creating a RAID 1 or 10 on new drives, or when you want to  
ensure that the new array contains no existing data.  
RAID 1,  
10  
Quick Init  
Fastest way to create a RAID 1 or 10. Appropriate when using a  
new drive.  
Note:  
Before adding a new drive to an array, back up any data contained on the new drive.  
Otherwise, all data will be lost.  
Only disk drives that were previously configured as simple volumes can be used for  
RAID 0 or 1 migration when the single/source drive has data on it. See Configuring  
Disk Drives on page 67 to create a simple volume.  
If you stop the build or clear process on a RAID 1 from ACU, you can restart it by  
pressing Ctrl+R.  
A RAID 1 and 10 created using the Quick Init option may return some data  
miscompares if you later run a consistency check. This is normal and is not a cause for  
concern.  
If you stop the migration process on a RAID 0, you can restart it by pressing Ctrl+R.  
To modify the Write Cache setting for an array, press Ctrl+W.  
The ACU allows you to use drives of different sizes in a RAID 1. However, during a  
build operation, only the smaller drive can be selected as the source drive.  
Appendix C: Using the ARC Utility  
65  
When migrating from single volume to RAID 0, migrating from a larger drive to a  
smaller drive is allowed. However, the destination drive must be at least half the  
capacity of the source drive.  
It is not recommend that you migrate or build an array on Windows dynamic disks  
(volumes), as it will result in data loss.  
5
When you are finished, press Done.  
Managing Arrays  
Select the Manage Arrays option to perform these tasks:  
Rebuild Arrays

The following sections describe these operations in greater detail.  
Rebuilding Arrays  
Note: Rebuilding applies to Fault Tolerant arrays (RAID 1) only.  
By replacing a failed drive of a RAID 1 array with a new drive, you can rebuild to get the array  
to Optimal status and assume fault tolerance. You can perform a rebuild in the following ways:  
Note: If no spare exists and a hard disk drive fails, you need to create a spare before you  
can rebuild an array. See Adding/Deleting Hotspares on page 66 before continuing your  
rebuild.  
System Shutdown Rebuild  
You can shut down the system and replace the failed drive with a new one (of equal or  
greater capacity). When the system is booted, you can assign the new drive as a spare, and  
this will start the Rebuild task. All the data from the good drive is copied to the new one,  
and the original RAID 1 array is recreated.

Using the AFU for DOS  
In this chapter...  
This chapter describes how to use the Adaptec Flash Utility (AFU), a text-based DOS utility  
that you can use to update, save, or verify the HostRAID controller’s firmware BIOS.  
Caution: Although the AFU contains safeguards to prevent you from accidentally damaging  
your HostRAID controllers flash contents, it is still important to use the AFU carefully and  
!
correctly to avoid rendering your HostRAID controller inoperable. Adaptec recommends that  
only advanced users familiar with working in DOS use the AFU. For more information, see  
   
Appendix D: Using the AFU for DOS  
71  
Introduction  
The AFU is a DOS utility used to update, save, or verify the HostRAID controller’s firmware  
BIOS.  
The AFU is easy to use and contains safeguards to prevent you from accidentally damaging the  
HostRAID controller’s flash contents. Still, you must be careful to use the AFU correctly,  
otherwise, you could render the HostRAID controller inoperable.  
The AFU is used to:  
Update—Updates all the flash components on a HostRAID controller with the flash image  
data from a User Flash Image (UFI) file.  
The AFU updates the HostRAID controller’s flash by reading UFI files and writing them to  
the controller’s flash components.  
Note: The UFI includes the HostRAID controllers type, thereby ensuring that the AFU  
uses the correct file.  
Save—Updates and verifies the BIOS image of the controller.  
Verify—Reads the contents of a HostRAID controller’s flash components and compares it  
to the contents of the specified UFI file.  
Version—Displays version information about a HostRAID controller’s flash components.  
List—Lists all supported HostRAID controllers detected in your system.  
System Requirements  
The requirements for AFU are as follows:  
MS–DOS version 5.0 or later. It cannot run from a DOS command prompt window under  
any version of Windows.  
Note: You cannot create a bootable floppy using Windows 2000.  
At least 8 MB of extended memory.  
Compatibility  
The AFU has the following compatibility issues:  
Supports HIMEM.SYS and is compatible with other DOS drivers running under  
HIMEM.SYS (for example, SMARTDRV.SYS and SETVER.SYS).  
Does not support DOS extenders installed in memory, such as EMM386.SYS and  
DOS4GW.  
Running the AFU from the GUI  
The easy way to run the AFU is to use its GUI. If you prefer to run the AFU from the command

Select Select an Operation and choose one of the available options, then follow the  
on-screen instructions.  
Running the AFU from the Command Line  
At the DOS command prompt (typically A:\>), type AFUfollowed by a command and any  
switches. The AFU processes the command, prompts you to insert additional floppy disks as  
needed, exits, and reports success or an error message code. The following available commands  
are summarized in alphabetical order.  
HELP  
The HELPcommand displays a summary of AFU functions and command switches.  
Examples  
The following are examples of command syntax that will work to get help:  
A:\> AFU HELP  
A:\> AFU /?  
LIST  
The LISTcommand displays the AFU-supported HostRAID controllers installed on your  
computer. Use this command to see which HostRAID controllers are installed, or to identify  
the ID numbers assigned to each physical controller.  
You do not have to restart the computer after completing this command.  
Example  
This example shows a typical system response to a LISTcommand:

SAVE  
The SAVEcommand saves the contents of a HostRAID controller’s flash in a UFI file. The name  
of the UFI file is based on the HostRAID controller type and cannot be changed.  
Command Syntax  
The command syntax for the SAVEcommand is as follows:  
AFU SAVE [/C<Controller ID>] [/D <UFI File Path>]  
Command Switches  
The following switches are available:  
/C <Controller ID> is one or more HostRAID controller IDs representing the set of  
controllers on which to perform the specified command. The default is 0, which means  
that if the computer has multiple HostRAID controllers, the AFU defaults to controller 0  
unless you specify otherwise.  
You can specify a single HostRAID controller ID, for example:  
/C 0  
multiple IDs separated by commas, for example:  
/C 0,2  
or ALLto indicate all HostRAID controllers.  
Note: If you are using multiple HostRAID controllers, you must specify the controller  
you want by using the /C switch; otherwise, the AFU displays an error message and  
exits. You cannot select ALL HostRAID controllers when specifying SAVE.  
/D <UFI File Path> specifies the path (drive and directory) where the UFI files are located.  
If you do not specify the /D switch, the AFU looks for, or creates, UFI files in the default  
location.  
Note: You cannot specify the name of a UFI file, only its path. UFI filenames are  
predefined, based on the HostRAID controller type.  
Examples  
In the following example, the AFU saves flash contents from HostRAID controller 0 to a UFI  
file in the current default drive and directory:  
A:\> AFU SAVE /C 0  
In the following example, the AFU saves flash contents from Controller 1 to a UFI file in  
C:\UFI_FILES.  
A:\> AFU SAVE /C 1 /D C:\UFI_FILES  
 
Appendix D: Using the AFU for DOS

If you have multiple HostRAID controllers only—At the DOS prompt, type afu list,  
then press Enter.  
This command displays the Adaptec SAS HostRAID controllers in your system. Note the  
HostRAID controller number for the controller you want to update; you may need it in  
Step 6 to perform the update.  
You can update the flash using any of the following alternatives:  
a
b
Updating the Flash on a Single HostRAID ControllerTo flash the firmware on a  
single HostRAID controller, type:  
afu update /C <controller_number>  
Where controller_numberis the number of the controller whose firmware you are  
updating. For example, to upgrade Controller 0, type:  
afu update /C 0  
Updating the Flash on Multiple ControllersTo flash the firmware on multiple  
HostRAID controllers, type:  
afu update /C <controller_number_a>,<controller_number_b>  
Where <controller_number_a>and <controller_number_b>are the number of one  
of the Adaptec HostRAID controllers whose firmware you are updating.  
To upgrade HostRAID controllers 0, 2, and 3 for example, type:  
afu update /C 0, 2, 3  
c
Updating the Flash on All HostRAID Controllers SimultaneouslyTo flash the  
firmware on all HostRAID controllers, type:  
afu update /C all  
Note: The UFI file identifies the appropriate HostRAID controllers, so you do not  
have to worry about flashing the wrong controller.  
7
The AFU prompts you to put in the first firmware disk.  
When it detects that the disk is in the drive, the AFU reads the part of the firmware image  
contained on the first disk.

9
When prompted, remove the first firmware disk and insert the second firmware disk.  
If necessary, repeat Step 8 until the process is complete.  
 
Safety Information  
E
To ensure your personal safety and the safety of your equipment:  
Keep your work area and the computer clean and clear of debris.  
Before opening the system cabinet, unplug the power cord.  
Electrostatic Discharge (ESD)  
Caution: ESD can damage electronic components when they are improperly handled, and  
can result in total or intermittent failures. Always follow ESD-prevention procedures when  
removing and replacing components.  
!
To prevent ESD damage:  
Use an ESD wrist or ankle strap and ensure that it makes skin contact. Connect the  
equipment end of the strap to an unpainted metal surface on the chassis.  
If a wrist strap is not available, ground yourself by touching the metal chassis before  
handling the controller or any other part of the computer.  
Avoid touching the controller against your clothing. The wrist strap protects components  
from ESD on the body only.  
Handle the controller by its bracket or edges only. Avoid touching the printed circuit board  
or the connectors.  
Put the controller down only on an antistatic surface such as the bag supplied in your kit.  
If you are returning the controller to Adaptec, put it back in its antistatic bag immediately.

across all members in equal-sized sections called stripes.  
             
Glossary  
93  
stripe size  
The amount of data in each section of a striped array.  
striped array  
See RAID 0, RAID 10.  
T
task  
An operation that occurs only on the RAID controller, asynchronous to all other operations; for example,  
initializing a disk or verifying an array. Some tasks can take an extended period of time, particularly if the  
RAID controller is also performing intensive data I/O while the task is running.  
V
verify  
Low-level check that a drive, logical device, or hot spare is good. In a RAID 1, verify is a low-level check that  
contents of both members’ segments are consistent and, optionally, corrects errors while assuming that the  
master drive is correct. In a simple volume, verify performs a low-level check that the whole drive can be  
read.
