Installing drives into the  
RAID Tower XIII  
Door Lock  
1.  
Be sure the lock on each drive doors  
is in an unlock position. If not use the key  
that comes with the Disk Array to unlock the  
drive door. Pull on the door lever to swing  
open the drive door all the way.  
2.  
Slide a 3.5” SATA hard drive into the  
drive slot with the drive connector side  
facing in. Be sure to orient the hard drive  
with t  
right  
correctly as shown in the yellow label on the  
inside of the drive door – with drive door  
swing open at the bottom, the top of the hard  
drive should face to the right. The drive  
should slide all the way into the slot with  
very little resistance. Forcing the drive into  
the slot will cause the drive damage or  
permanent damage to the Disk Array.

3.  
Once the drive is all the way into the  
Drive Power &  
Activity LED  
driver slot, close the door all the way until  
the drive door latches securely. This will  
engage power and data connection with the  
hard drive. The LED light for the drive slot  
should light if the Disk Array already is  
powered on. You may lock the drive door  
with the key.

To remove the hard drive from the  
Disk Array, simply follow the steps 2-3 in  
reverse.  
Resetting the RAID Mode  
NOTE: This procedure destroys all RAID data. It should not harm individual  
drives or their contents; however, creating or running backups of all data is  
strongly recommended before proceeding.  
1.  
Power down the unit and set the dip switch to the factory default  
setting (all switches OFF).  
2.  
While holding the SET button with a ballpoint pen, turn the unit on. A  
long beep will sound from the Port Multiplier. The SET button may be released  
once the long beep stops.

Setting or Modifying the RAID Mode  
NOTE: Setting or modifying the RAID mode destroys all data.  
1.  
2.  
3.  
Follow the procedure for resetting the RAID Mode.  
Power down the unit and set the dip switch to the desired RAID Mode.  
While holding the SET button with a ballpoint pen, turn the unit on. A  
long beep will sound from the Port Multiplier. The SET button may be released  
once the long beep stops.  
If instead of a long beep the Port Multiplier sounds a series of short beeps, an  
error has occurred during configuration of the array.  
Windows users may install the JMicron HW RAID Manager application located  
on the SATA Controller CD. In the CD, browse to Configuration Utilities →  
JMB393. The JMicron HW RAID Manager can be used to create, modify, and  
monitor the health status of the RAID drives, and provide status alerts. When  
configuring the RAID mode using the RAID Manager application, it is strongly  
recommended to leave the dip switch in the factory default setting.  
Using identical drives for all settings other than JBOD or LARGE is strongly  
recommended. Creating a LARGE array using drives that have different  
properties will use all space on all members, and performance will match that  
of the member in use during any particular I/O operation. Creating a RAID  
using drives that are not all the same size will result in all members using only  
as much space as the smallest member. Creating a RAID using drives that  
have different performance will degrade the overall performance of the array.  
BZS Switch (SW1:1):  
The BZ switch is used to silence the audible alarm buzzer. The OFF position  
permits the audible alarm, and the ON position silences the audible alarm.  
The BZ switch has immediate effect.  
EZ Switch (SW1:2):  
The EZ (spare) switch inhibits spares when ON. When in the OFF position,  
all individual drives (not defined as members of an array) are considered  
spare. Should a RAID become degraded, when the EZ switch is in the OFF  
position a spare drive will be used automatically to rebuild the RAID, if  
present. EZ mode is determined when the unit is powered up. Changing the  
switch will have no effect until the unit has been re-powered.

RAID Mode Switches M2, M1, M0 (SW1:3 – SW1-5)  
The RAID Mode switches define what type of RAID will be initialized when  
the unit is powered up while the RAID Mode button is held down. Each type  
of RAID has different properties and requirements, as follows:

JBOD Mode (Individual Drives)  
Number of drives: at least 1  
Unit capacity: N/A (100% of each individual drive)  
Spares: no  
Fault tolerance: none  
JBOD mode offers all connected units to the host adapter, no RAID is defined  
at all.  
NOTE: JBOD mode requires a SATA controller featuring Port Multiplier  
support for eSATA connections.  
NOTE: Optical drives can only be configured as JBOD using an eSATA  
connection.  
RAID 0 (Stripe set)  
Number of drives: at least 2  
Unit capacity: size of each member times number of members.  
Spares: no  
Fault tolerance: none - if any member is lost all data is lost.  
RAID 0 “stripes” the file system across the array by placing sectors of data  
sequentially between drives in a specific order.

Phone: 408-453-6212  
RAID 1 or 10 (Mirror set, Stripe of mirror sets)  
Number of drives: 2 (RAID 1) or 4 (RAID 10).  
Unit capacity: size of one member (RAID 1) or size of two members (RAID  
10).  
Spares: yes – if EZ mode is not disabled and 3 (RAID 1) or 5 (RAID 10)  
drives are present, the array will be initialized with a spare.  
Spares: yes – if EZ mode is not disabled and 3 (RAID 1) or 5 (RAID 10)  
drives are present, the array will be initialized with a spare.  
Fault tolerance: RAID 1 can withstand the loss of one drive without losing  
data. RAID 10 can withstand the loss of one drive from each mirror set  
without losing data.  
RAID 1 works by duplicating the exact same data on two drives.  
RAID 10 works by using two RAID 1 sets configured as members of a RAID  
0. Disks 1 and 2 are mirrored, disks 3 and 4 are mirrored, and the two mirror  
sets are striped together.  
RAID 3 (Stripe set with dedicated parity)  
Number of drives: at least 3  
Unit capacity: size of one member times number of members minus one.  
Spares: yes  
Fault tolerance: can withstand the loss of one drive without losing data.  
RAID 3 works by striping data for individual I/O blocks across all members  
except one, which contains parity data for the stripe set computed by the Port  
Multiplier.  
RAID 5 (Stripe set with striped parity)  
Number of drives: at least 3  
Unit capacity: size of one member times number of members minus one.  
Spares: yes  
Fault tolerance: can withstand the loss of one drive without losing data.  
RAID 5 works by striping entire I/O blocks across all members of the set, with  
each member taking turns carrying parity data computed by the Port  
Multiplier.  
CLONE (Mirror set)  
Number of drives: at least 2  
Unit capacity: size of one member.  
Spares: yes  
Fault tolerance: can withstand the loss of any number of drives without losing  
data as long as at least one complete member remains online.  
Technical Support (M-F 8:30am - 6:00pm PST)  
Phone: 408-453-6212  
CLONE mode works the same way as RAID 1, by maintaining a complete  
copy of the entire set of data on each drive.  
LARGE (Spanned set)  
Number of drives: at least 2  
Unit capacity: 100% of all drives together regardless of differences in size  
Spares: no  
Fault tolerance: cannot withstand the loss of any drives without losing data.  
However, some data may be recovered as long as the drive(s) carrying the  
file system data (boot record, directory, etc.) remain online.  
LARGE mode is neither a RAID nor is it a JBOD. It works by declaring the  
sum of all available space of the member drives as a single unit, without  
striping the data. As each member is filled, new data is stored on the next.
