Chapter 1 Hardware Configurations  
This chapter explains hardware configurations for the ETERNUS DX Disk storage system.  
1.1  
Controller Enclosure  
This section explains the main components in the controller enclosure.  
The controller enclosure contains disks installed in the front, and controllers and power supply  
units in the rear.  
Since the power supply units are redundant, operations can continue even if one of them fails.  
There are two models: a single-controller type and a dual-controller type. For a dual-controller  
type, operations can continue even if one of the controllers fails.  
The single-controller type differs from the dual-controller type by the fol-  
lowing features:  
IMPORTANT  
- The controller and expander are not duplicated.  
- Hot maintenance or swapping of the controller and expander is not  
possible.  
- Concurrent firmware loading or update of the controller firmware and  
expander firmware is not possible.  
- Multipath connection to a single server is not available.  
Fujitsu recommends that the dual-controller types, in which the controller  
and expander are duplicated, be used in a system where a high level of  
reliability is required.

Enclosure Connection Path  
For a dual-controller type, a controller enclosure (CE) is connected to a drive enclosure (DE) with  
multiple paths.  
A drive enclosure has two independent DI ports. Path redundancy is maintained by connecting  
the drive enclosure to two controllers directly. This configuration allows operation to continue  
even if one of the connection paths fails.

Chapter 2 ETERNUS DX Disk Storage System Installation  
2.4 Installation Environment  
2.4  
Installation Environment  
Sufficient consideration of the installation environment should be taken to ensure proper use of  
the ETERNUS DX Disk storage system. Using the ETERNUS DX Disk storage system in an  
environment that does not satisfy the installation environment requirements may cause a failure  
to occur with the ETERNUS DX Disk storage system.  
2.4.1  
Air Conditioning  
It is important to consider the flows of cooling air (intake air) and exhaust air for the installation  
location. The temperature in some ETERNUS DX Disk storage systems may rise when exhaust  
air is taken in from other ETERNUS DX Disk storage systems. In addition, check other factors  
that might affect the usage environment temperature, such as the room size, whether other  
ETERNUS DX Disk storage systems are installed, and how many people are present in the  
room.  
When installing air conditioning, the ambient temperature should be considered.  
Ambient temperature  
An ETERNUS DX Disk storage system is cooled by taking in air through the front intakes and  
pushing out the exhaust air through the rear of the ETERNUS DX Disk storage system. If the  
intake air temperature does not meet the ambient environment conditions, a temperature  
error occurs and the power of the ETERNUS DX Disk storage system is shut down.  
- Front intake air temperature  
Make sure that the front intake air temperature is between 5 and 40°C.  
- Rear exhaust air temperature  
For example, when the intake air temperature is 40°C, the exhaust air temperature is 45°C  
or higher.  
Check the heat generation amount and the exhaust air amount that are listed in "2.1  
Installation Specifications" (page 26) for the necessary cooling capacity of air conditioning.  
2.4.2  
Earthquake Resistance  
Take the necessary measures (e.g. secure the rack to the floor or wall) to prevent a rack in which  
an ETERNUS DX Disk storage system is installed from falling down when earthquakes occur.  
Earthquake countermeasures vary depending on the installation location, the floor conditions,  
and the type of rack that is used. Contact your installation contractor for more details regarding  
earthquake countermeasure methods and how work should be conducted.

2.4.3  
Load Bearing Capacity for Floors  
Make sure that the following relationship between the load bearing capacity of the floor and the  
weight of the ETERNUS DX Disk storage system is maintained.  
(Load bearing capacity of the floor) > (ETERNUS DX Disk storage system weight ÷ Installation  
area that includes service areas)  
If the condition above is not satisfied, additional measures are required to ensure sufficient load  
bearing capacity. Contact your installation contractor for details about the necessary measures  
that must be taken.  
2.5  
Outlet/Socket Specifications  
Power can be supplied to the ETERNUS DX Disk storage system from two power sources  
because each enclosure has two power supply units.  
During normal operation, each of the power sources supplies half of the necessary power.  
When one of the power supply lines fails, all of the necessary power is supplied from only one  
power source.  
Using the same power supply condition for all of the power supply units is recommended so that  
different power supply conditions (such as whether power distribution units are used or not and  
input voltage) are not used for the ETERNUS DX Disk storage system.  
This section explains the power connection specifications of the ETERNUS DX Disk storage sys-  
tems.  
2.5.1  
Specifications for Optional Power Supply Products  
This section explains the specifications of optional power cords and power related optional prod-  
ucts.  
When using power distribution units, the number of outlets that are required for controller enclo-  
sure and drive enclosure connection should be taken into consideration.  
In addition, make sure that the plug type of the power distribution unit fits the power socket when  
using an existing power socket. If the plug type does not fit the power socket, replace the socket.

2.5 Outlet/Socket Specifications  
2.5.2  
Required Number of Outlets/Sockets  
The number of power outlets/sockets required to install the ETERNUS DX Disk storage system  
depends on the number of drive enclosures and power distribution units.  
It is recommended that the power cord of a drive enclosure is connected to the power distribution  
unit that is installed in the same rack. Secure the necessary number of power outlets within the  
same rack to avoid connecting power cords to power outlets in different racks. It may be neces-  
sary to purchase additional power distribution units depending on the installation locations of  
enclosures.  
Without power distribution units  
Two power sockets are required for each enclosure (controller enclosure and drive enclosure).  
With power distribution units  
Two power sockets are required for each power distribution unit. There are three types of power  
distribution units. The size and number of outlets are different for each type.

Chapter 3 Connections  
This chapter explains connections for the ETERNUS DX Disk storage system.  
3.1  
Host Connections  
FC, iSCSI, and SAS host interface models are available for the ETERNUS DX60 S2. The server  
and the ETERNUS DX Disk storage system can be connected directly or via a switch.  
3.1.1  
Host Interfaces  
This section describes each host interface.  
FC (Fibre Channel)  
FC supports two connection topologies: Fibre Channel Arbitrated Loop (FC-AL) and Fabric.  
Direct connections and switch connections to servers are available.  
The maximum transfer speed is 4Gbit/s.  
When FC switches are used, zoning should be set for the FC switches to  
ensure the security of data.  
iSCSI  
Direct connections and switch connections to servers are available.  
The maximum transfer speed is 1Gbit/s.  
In order to maintain iSCSI performance, the iSCSI network should be physically separated from  
other types of networks (such as networks for Internet access and file transfers).  
CHAP  
CHAP authentication can prevent unauthorized access. The following CHAP authentication  
methods are supported:  
- Unidirectional CHAP  
- Bidirectional CHAP  
Jumbo Frame  
Enabling Jumbo Frame makes data transfer more efficient by increasing the amount of data  
that can be transferred for each Frame.

Server-side CPU load can be reduced by using Jumbo Frame.  
However, I/O performance may be reduced by 10% to 30%.  
When using a LAN switch that supports the Flow Control function,  
disable the Flow Control function.  
When connecting to a server with VMware vSphere 4.0/4.1, disable  
the Flow Control function of the LAN switch.  
SAS  
Simple, cost effective, and high performance network storage environment can be configured.  
Direct connections to servers are available.  
The maximum transfer speed is 3Gbit/s.  
Up to two paths are allowed when the ETERNUS Multipath Driver is used.  
3.1.2  
Host Connection Path  
This section explains the connection configuration between a server Host Bus Adapter (HBA)  
and an ETERNUS DX Disk storage system host interface port.  
Single path configuration  
A single path configuration connects the ETERNUS DX Disk storage system to a server via a  
single path.  
The server cannot access an ETERNUS DX Disk storage system when a component (such as a  
controller, HBA, switch, or cable) on the path has a problem. The system must be stopped during  
the replacement of failed components and controller firmware.  
In a single path connection configuration, the path failover and load balancing functions are not  
supported.  
A multipath connection configuration is recommended to maintain availability when a problem  
occurs.

Multipath configuration  
A multipath configuration connects the ETERNUS DX Disk storage system to a server via multi-  
ple paths (multipath). System reliability is improved due to the path redundancy. For multipath  
connections, driver software to control multipathing is required.  
If a path fails, access can continue by using the path failover function that switches access from  
the failed path to another path. The performance of the system can be improved by using the  
load balancing function to spread the access load over multiple paths.  
To use the load balancing function, four or more paths must be used to con-  
nect the server and the ETERNUS DX Disk storage system.

When configuring multipathing for reliability, make sure to configure a  
redundant connection for the controllers of the ETERNUS DX Disk storage  
system. Configure paths to connect to different controllers (CM#0 and  
CM#1). Combinations of host interface port numbers (Port#0 and Port#1) in  
controllers do not need to be taken into consideration.  
Cluster configuration  
When a server is duplicated in a cluster configuration and the ETERNUS DX Disk storage sys-  
tem is shared by multiple servers, software to control the cluster configuration is required.

LAN for operation management  
In an ETERNUS DX Disk storage system, the system administrator logs on to the ETERNUS DX  
Disk storage system via a LAN to set the RAID configuration, manage operations, and perform  
maintenance. The computer for operation management that is used for accessing the ETERNUS  
DX Disk storage system via ETERNUS Web GUI or ETERNUS CLI is called an administration  
terminal.  
In addition, the functions that are provided by the management/monitoring server on the LAN can  
be used. These functions include SNMP (device monitoring), SMTP (e-mail sending), and NTP  
(time correction).

3.3 Power Supply Connection  
LAN for remote support  
Various failures that occur in the ETERNUS DX Disk storage system are notified to the remote  
support center. Remote support connection can be separated from the LAN for operation man-  
agement.  
3.3  
Power Supply Connection  
Connect the power cords (AC cables) of the ETERNUS DX Disk storage system to the power  
sockets, the UPS sockets, or the power control unit sockets.  
Refer to "2.5 Outlet/Socket Specifications" (page 31) for details about the types and the number  
of power outlets/sockets.  
Two power supply units (PSU#0 and PSU#1) are installed in each enclo-  
sure. Make sure that power cords are connected to both of the power sup-  
ply units.  
3.3.1  
Input Power Supply Lines  
Multiple power supply facilities in the building or UPS units are recommended for power supply  
redundancy. When the ETERNUS DX Disk storage system power supply is redundantly config-  
ured, business can continue even if one of the power lines fails.  
To connect the ETERNUS DX Disk storage system to power supply facilities, use the following  
configurations to improve the availability of the power supply facilities if a power supply facility  
failure occurs.  
Connect the power cords of PSU#0 and PSU#1 to different lines.  
When a power distribution unit is used, separately connect it to line 0 (PSU#0) and line 1  
(PSU#1).  
Alternatively, optimal system design (including the server) may instead lead to the ETERNUS DX  
Disk storage system being configured with only a single power supply facility or UPS unit. Which  
configuration is selected will depend on system availability requirement considerations.

3.3 Power Supply Connection  
3.3.2  
UPS Connection  
It is recommended that an Uninterruptible Power Supply System (UPS) be used as the power  
supply source for the ETERNUS DX Disk storage system to cope with power outages and  
momentary voltage drops in the normal power supply.  
Note that when connecting an ETERNUS DX Disk storage system to a UPS with one power sup-  
ply line, the total value of the power requirements for all the enclosures must not exceed the UPS  
output capacity.  
When one of the power supply lines fails for redundantly configured UPS units with two power  
supply lines, all of the power for the ETERNUS DX Disk storage system must be supplied from  
the other line. Select a UPS that can supply sufficient power so that the total value of the power  
requirements does not exceed the UPS output capacity in case only one power supply line is  
available.  
For details about the necessary UPS output capacity, refer to the specifications of the UPS that  
is used.  
A UPS must satisfy the following conditions:  
Rating capacity  
Secure a sufficient rating capacity for the total value of the maximum power requirements for  
the enclosures that are to be installed.  
For the maximum power requirements of each enclosure, refer to "2.1 Installation  
Supply time  
Consider the power supply time of the battery to make sure that the ETERNUS DX Disk  
storage system power is not turned off before the server shuts down.  
Socket type  
If the power plug type and the socket type of the UPS do not match, it is necessary to equip  
the UPS (AC output) with an appropriate type of socket. Request a qualified electrician to  
perform the necessary work to make terminal block connections available.  
Power supply configuration  
If a UPS is used, make sure that it supplies power to all the enclosures.  
Configurations where the controller enclosure is powered by the UPS while the drive  
enclosure is powered directly from AC are not supported.

Power Synchronized Connections  
This section describes connections to automatically control powering the ETERNUS DX Disk  
storage system on and off with a server.  
Power synchronized unit  
A power synchronized unit enables the ETERNUS DX Disk storage system to be powered on  
and off with a server. The power synchronized unit detects changes in the AC power output of a  
UPS unit that is connected to a server (server UPS unit) and automatically turns on and off the  
ETERNUS DX Disk storage system. In addition to server UPS units, units that control the AC  
socket power output can also be connected. When three or more servers are connected, power  
can be synchronized by adding an AC sensor unit.  
The power synchronized unit detects the AC power output of the target devices for power syn-  
chronization and commands the ETERNUS DX Disk storage system to synchronize the power  
with the target devices.  
When the power synchronized unit detects the AC power output of any server UPS unit, the  
power synchronized unit commands the ETERNUS DX Disk storage system to turn on.  
When the power synchronized unit does not detect AC power output in any of the server UPS  
units, the power synchronized unit commands the ETERNUS DX Disk storage system to turn off.  
The server UPS unit must have a function in the management software that controls the AC  
power output according to when the server powers on and off. The server UPS unit must have  
one unused outlet to connect to the power synchronized unit.

Chapter 4 Rack and Optional Product Installation  
This chapter explains the requirements for installation of racks and the optional products for an  
ETERNUS DX Disk storage system.  
4.1  
Rack Installation Requirements  
This section explains the requirements for installing the ETERNUS DX Disk storage system in a  
19-inch rack.  
Enclosures are installed in the following order (from bottom to top).  
The center of gravity must be taken into consideration to prevent a rack from toppling over.  
Enclosures should generally be installed from bottom to top to lower the center of gravity and to  
ensure the safe use of racks.

Install the controller enclosure and drive enclosure in the same rack.  
When determining the rack-mounting layout, consider the placement of  
each enclosure and the power distribution unit in the rack and the length  
of each cable. For example, if the ETERNUS DX Disk storage system is  
installed at the top of a 1800mm rack, the surplus length of the power  
cord at the bottom of a rack should be about 2m.  
If the storage system is installed at the bottom of a rack, a space for the  
surplus of cables may not be available in some racks, preventing the  
storage system from being pulled out when maintenance work is  
required.  
In this case, secure a space of 1U or more at the bottom when installing  
the storage system.

The ETERNUS DX Disk storage system can be installed in a Fujitsu 19-inch rack. For informa-  
tion about whether the ETERNUS DX Disk storage system can be installed in an EOLed rack or  
not, contact your sales representative.  
4.2.2  
Non-Fujitsu Racks  
ETERNUS DX Disk storage systems are developed and their operation is guaranteed on the  
assumption that they are installed in Fujitsu 19-inch racks. Since the ETERNUS DX Disk storage  
system cannot be tested (for cooling and strength) in non-Fujitsu 19-inch racks, the operations of  
ETERNUS DX Disk storage systems cannot be guaranteed. Any problem that may occur by  
installing the ETERNUS DX Disk storage system in non-Fujitsu racks is not covered by the war-  
ranty.  
If the ETERNUS DX Disk storage system needs to be installed in a non-Fujitsu rack, the follow-  
ing conditions must be satisfied.  
Rack specifications  
Use the rack mount kit supplied with the product to install the ETERNUS DX Disk storage system  
in the rack. The rack specifications must satisfy the conditions listed below. For rack specifica-  
tions, refer to the manual that is supplied with the rack that is used.
