Removing Cover of RAID Tower

Loosen the 5 screws at the back of the tower for

the cover using a Philips screwdriver. Lift the

cover and pull slightly toward the rear of the tower

to disengage and remove.

Power LED: lit when RAID Tower is on.

Host LED: lit when array group is connected, blinks

during array activity.

Error LED: lit when array group has a problem, blinks

if a redundant array is rebuilding.

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.

Installing drives into the

RAID Tower XIII

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

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

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.

4. To remove the hard drive from the

Disk Array, simply follow the steps 2-3 in

reverse.

Setting or Modifying the RAID Mode

NOTE: Setting or modifying the RAID mode destroys all data.

1. Follow the procedure for resetting the RAID Mode.

2. Power down the unit and set the dip switch to the desired RAID Mode.

3. 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:

1 Audible alarm is recommended at all times.

2 EZ mode has no effect in JBOD mode.

3 Disabling EZ for RAID 0 and LARGE is strongly recommended.

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.

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.

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.
