Port Multiplier Compatibility
When configured as a set of individual drives and connected to a SATA or an 
eSATA host adapter, the Port Multiplier will only work with a Port Multiplier aware 
host. This includes setting up the unit with more than one array. Identify your host 
controller and check with its hardware manufacturer if you are unsure. Addonics 
offers several Port Multiplier aware host adapters.
Using identical drives for all settings other than JBOD or LARGE is stro\
ngly 
recommended. Creating a LARGE array using drives that have different proper-
ties 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 perfor-
mance will degrade the overall performance of the array.
Port Multiplier Modes
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 connec-
tion.
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 “c\
hunks” 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 (RA\
ID 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 losi\
ng 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 mirr\
or 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 membe\
rs 
except one, which contains parity data for the stripe set computed inter\
nally by 
the Port Multiplier. In the event of failure, the missing information can be 
calculated using the parity information.
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 Multi\
plier. 
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 enti\
re 
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 av\
ailable 
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 configure\
d 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 w\
hile 
the spares are disconnected from the Port Multiplier. When EZ mode is 
enabled (SW1:2 OFF), individual drives connected when an array is pres\
ent 
are considered spare. Spare drives must be equal to or larger in size th\
an the 
smallest member. When any type of array is defined, individual units will be 
considered spare.

Configuring the Port Multiplier Using Dipswitches
Resetting the RAID
NOTE: This procedure destroys all RAID data. It should not harm individual dri\
ves 
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 procee\
ding. The 
port multiplier will not complete the process if it has no host connecti\
on.
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 sound\
s 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 procee\
ding. The 
port multiplier will not complete the process if it has no host connecti\
on.
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 s\
hort 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 alar\
m. The 
BZS switch has immediate effect.
EZ Switch (SW1:2):
The EZ (spare) switch inhibits spares when ON. When in the OFF positio\
n, 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 automati\
cally to 
rebuild the RAID, if present. EZ mode is determined when the unit is pow\
ered 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 pred\
ictable. 
Disconnect any individual drives with valuable data on them before enabl\
ing 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. Each type of\
 RAID 
has different properties and requirements, as follows:
 NOTES:
  1. Audible Alarm is recommended at all times.
  2. EZ mode has no effect when no array is defined.
  3. Disabling EZ for RAID 0 and LARGE is strongly recommended.
Configuring the Port Multiplier Using the JMicron RAID Manager
Windows users may install the JMicron HW RAID Manager application locate\
d 
on the SATA Controller CD, or download it from 
http://addonics.com/drivers/driver_list.php. In the CD, browse to Config\
uration 
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 a\
nd 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 s\
etting.
Setting or Modifying the RAID Mode
This procedure briefly describes the steps for using the Jmicron RAID Ma\
n-
agers 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 updat\
ing 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 multipl\
ier 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 drive\
s 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, excep\
t 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 bei\
ng 
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.

The RAID and Disk Information screen (shown when the program was 
launched) will now show the Port Multiplier with an Array. The drives are now 
listed as M0-M4, indicating they are members of the array. If spares are 
present (individual drives added later, and the EZ switch is in the OFF 
position), they would be listed as S0, S1, etc. On the right pane, the \
RAID 
Level, status, capacity and members that are online are listed. Status w\
ill show 
“Normal” (all members on line), “Degraded” (a fault-toler\
ant array with a drive 
failure needing service), “Rebuilding” (a fault-tolerant array i\
n the process of 
reconstructing lost data onto a spare) or “Broken” (an array tha\
t has lost all 
data).
In the event of a drive failure, the Jmicron RAID Manager will present a\
 dialog 
box such as the one shown below, even if it is currently minimized to the system 
tray:
