							Port Multiplier Compatibility
The  Port  Multipliers  in  this  unit  will  only  work  with  a  Port  Multiplier  aware  eSATA host
adapter  when  configured  in  JBOD  Mode  (individual  drives).  Identify  your  host  controller
and check with its hardware manufacturer if you are unsure. Addonics offers several Port
Multiplier aware host adapters.
Hot Swapping
This unit supports hot swapping (inserting or removing drives while the drives are running
and  connected  to a computer).  The  eSATA controller  on  the  computer  must  also  support
hot  swapping - be sure to confirm this before attempting to insert or remove drives  while
the  system  is  running.  Also  be  sure  to  practice  the  appropriate  safe  removal  procedure
before  proceeding.  Failure  to  practice  safe  removal  procedures  will  result  in  loss  or
corruption of data.
Drive Installation
1.  Remove  tray  and  align  drive  with
mounting  holes  as  indicated.  The
drives connector end should protrude
from the tray slightly.
2.  Secure  the  drive  to  the  tray  using
four large flat  screws  on a 3.5”  drive,
or  three  of  the  smaller  screws  for  a
2.5” drive.
3.  Insert  tray  into  Disk  Array,  drive
label side up, lever open. Push gently
until the tray stops, dont force it.
4.  Secure  the  tray  into  position  by
pressing  the  lever  closed.  If  desired,
rotate the lock.

							Port Multiplier Modes
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.
The  Port  Multiplier  supports  individual  drives  (JBOD  Mode),  several  types  of  RAID  and
some non-RAID drive sets. Each configuration 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 “chunks” 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  internally  by  the Port  Multiplier.  In
the event of failure, the missing information can be calculated using the parity information.
Phone: 408-453-6212 Email: www.addonics.com/support/query/    4 
						

							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. In the event  of
failure, the missing information can be calculated using the parity information.
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 while the spares
are  disconnected  from  the  Port  Multiplier.  When  EZ  mode  is  enabled  (SW1:2  OFF),
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 to replace a failed member.

							Configuring the Port Multiplier Using Dipswitches
Resetting the RAID
NOTE:  This  procedure  destroys  all  RAID  data.  It  should  not  harm  individual  drives  or
their  contents;  however,  creating  backups  of  all  data  is  strongly  recommended  before
proceeding.
Be  sure  the  port  multiplier  is connected  to  an  active  host  before  proceeding.  The  port
multiplier will not complete the process if it has no host connection.
1. Power down the unit and set the dip switch to the desired RAID Mode.
2.  While  holding  the  SET  button,  turn  the  unit  on.  A long  beep  will  sound  from  the  Port
Multiplier. The SET button may be released once the long beep starts.
Shortly  after  releasing  the  SET  button,  the  port  multiplier  should  “chirp”  to  indicate  the
process is complete. If instead of a chirp the Port Multiplier sounds a series of short beeps,
an error has occurred during the process.
Setting or Modifying the RAID Mode
NOTE: Setting or modifying the RAID mode destroys all data.
Be  sure  the  port  multiplier  is connected  to  an  active  host  before  proceeding.  The  port
multiplier will not complete the process if it has no host connection.
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 starts.
Shortly  afterward,  the port  multiplier  should  “chirp”  to  indicate  the  process  is  complete.  If
instead of a chirp the Port Multiplier sounds a series of short beeps, an error has occurred
during configuration of the array.
BZS Switch (SW1:1):
The BZS 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  BZS  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 and are not offered to
the operating system. 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.
Warning: turning off the EZ switch to rebuild an array will consider any drives not declared
array members to be eligible for rebuild as a spare. Rebuilding will destroy all existing data
on that drive and the drive chosen is not predictable. Disconnect any individual drives with
valuable data on them before enabling EZ Mode.

							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, as follows:
Dipswitch Position1
(BZS)12
(EZ)3
(M2)4
(M1)5
(M0)

							Configuring the Port Multiplier Using the JMicron RAID Manager
Windows  users  may  install  the  JMicron  HW  RAID  Manager  application  located  on  the
SATA Controller CD, or download it from http://addonics.com/drivers/driver_list.php. In the
CD, browse to Configuration Utilities → JMB393.
Mac  and  Linux  users  may  download  those  versions  of  the  same  utility  from
http://addonics.com/drivers/driver_list.php under “Port Multiplier & Hub.” The JMicron RAID
Manager can be used to create, modify, and monitor the health status of the RAID drives,
and  provide  status  alerts  with  dialog  boxes  and  even  email.  When  configuring  the  RAID
mode  using  the  RAID  Manager  application,  it  is  strongly  recommended  to  leave  the  dip
switch in the factory default setting.
Setting or Modifying the RAID Mode
This  procedure  briefly  describes the steps for using the Jmicron RAID Managers Basic
Mode  to  create  an  array.  The  example  shown  is  a  LARGE  set.  There  are  other  options
available in the Advanced Modes, including building arrays using specified drives, setting
up  email  notifications,  and  updating  the  firmware  –  which  are  not  discussed  in  this  user
guide.
After starting the Jmicron RAID Manager, the first screen will show the status of any Port
Multipliers  detected  and  any  drives  connected. Shown  below  is  a  Port  Multiplier  with  a
variety of five drives connected:
On the left pane is “Controller 1” which is the first port multiplier detected by the software.
Shown  in  a  tree  view  are  the  five  drives,  listed  as  P0-P4.  These  are  currently  individual
drives. On the right pane is a listing of the drives and below that is a graphical view of each
drive. “Disk 1” through “Disk 4” indicate which physical port the drive is connected to. For
the AD5HPMSXA,  AD5HPMRXA-E,   and AD5HPMREU this refers to ports P0-P4. On the
CPR5SA unit,  this  refers  to  HD0-HD4.  On  the  AD5EHPMEU3  this  refers  to  D1-D5.  On
RAID Tower products this relates to the drives mounted left to right or top to bottom, except
in cases where a drive map is included showing otherwise.

							Next, click the Basic RAID Configuration tab and select the type of RAID desired. Note that
RAID  1  is  currently  disabled  as  an  option  since  more  than  two  individual  drives  are
available, and DELETE ALL RAID is disabled since there are currently no arrays to delete.
Shown below is the same set of drives being selected as a LARGE array.
Finally, click Apply. The Jmicron RAID Manager will confirm the operation with a reminder
that existing data on the drives will be lost, then perform the RAID configuration and report
with a dialog box when it is complete.
