RAID Rack with Port Multiplier Compatibility
Note: When configured as a set of individual drives, the Port Multiplier
will only work with a Port Multiplier aware host. Identify your host control-
ler and check with its hardware manufacturer if you are unsure. Addonics
offers several Port Multiplier capable host adapters.
Power Supply and Host Connection
The redundant power supply provides 500W of power. Before turning on
the main switch located on the front panel of the RAID Rack, connect and
switch on both units in this power supply. If only one power supply is
running, an audible alarm will sound.
Connect each array to a computer using the provided eSATA cables
before powering up the RAID Rack.

Installing drives into the RAID Rack
1. Be sure the lock on each drive door 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
drive damage or permanent damage to the Disk Array.
3. Once the drive is all the way into the drive slot, close the door all the way till the
drive door latch securely. This will engage power and data connection with the
hard drive. The LED lit for the drive slot should lit if the Disk Array already
powered on. You may lock the drive door with the key.
4. To remove the hard drive from the Disk Array, simply follow the step 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. 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:

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.
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.

Notes about Spare Drives
If EZ mode is disabled (SW1:2 ON), all individual drives not configured as
array members will be offered to the host adapter as separate units.
To create an array with one or more spares, set or modify the RAID mode
using fewer than 5 members, while the spares are disconnected from the
Port Multiplier. When EZ mode is enabled, individual drives connected when
an array is present are considered spare.
Spare drives must be equal to or larger in size than the smallest member.
When any type of array is defined, individual units will be considered spare.
RAID 0 and LARGE arrays are not fault-tolerant and spare drives will not be
useful; therefore, disabling EZ for these arrays is recommended.
When a spare drive is present and a fault-tolerant RAID (1, 10, 3, or 5) is
defined, EZ mode will automatically rebuild any available spares into the
array.
