Cipher Chain Module
The Cipher hardware in the R14CCES is activated by either powering up th\
e 
unit or pressing the Cipher Reset button with the Cipher Key inserted. Withou\
t 
activating the Cipher hardware, no drives in the Raid Rack will be visib\
le to the 
computer. Once the Cipher hardware is activated, the amber Cipher LED will 
glow and the drives will be available, and the Cipher key may be removed\
. If 
the Raid Rack is powered down or the Cipher Reset button is pressed, the\
 key 
will need to be reinserted and the Raid Rack powered up or the reset but\
ton 
pressed while the key is inserted for the unit to resume normal operatio\
n. All 
I/O operations are encrypted so drives must be partitioned and formatted\
 as if 
they were blank once installed in the Raid Rack. Should a drive with enc\
rypted 
data be removed from the Raid Rack and installed elsewhere, it will appe\
ar to 
be completely blank with no partition table or file system.
Port Multiplier Compatibility
The R14HPCCES unit only supports configuring the drives in RAID configur\
a -
tion. For JBOD installations, the R14CCES unit is recommended instead. 
When configured as RAID, the controller is not required to support port \
multipliers.
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 RAI\
D 
using drives that are not all the same size will result in all members u\
sing 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.
Hot Swapping drives
The R14HPCCES unit supports h ot 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 syst\
em is 
running. Also be sure to practice the appropriate safe removal procedure 
before proceeding. Failure to practice safe removal procedures will resu\
lt in 
loss or corruption of data. 
						

							Installation (RAID)
The Cipher hardware prevents the use of software to configure or manage \
the 
Port Multiplier. Configuring a RAID mode must be done using the dipswitches 
and SET button on the port multiplier itself, located inside the unit at the re\
ar of 
the chassis.
Installation
1. Use the provided key to unlock the front door if needed and open it.
2. Insert a drive into each bay as desired, SATA connectors first, label side up 
as shown, then press the drive firmly into place.
3. Connect the Host eSATA cable to a computer. If desired, connect an exter-
nal eSATA drive to the Drive eSATA connector.
4. Make sure the AC input switch is set correctly, then connect the power cord 
to an AC outlet.
5. Insert the Cipher Key into the Cipher 
Keyhole.
6. Set the AC power switch on the rear to 
ON, then press the power button
behind the front door to turn on the unit.
7. After the unit has been powered up, the 
Cipher Key may be removed.
To remove a drive, pull the Eject Lever until 
the drive disengages from the internal 
connector then pull the drive out.
Port Multiplier Modes
The Port Multiplier supports several types of RAID and some non-RAID dri\
ve 
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 is not supported on the R14HPCCES.
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 calcu-
lated 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 usi\
ng 
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 
while 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.
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 d\
efined, EZ 
mode will automatically rebuild any available spares into the array to r\
eplace 
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 recom -
mended 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 using the AC power switch on the rear, then 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.
After releasing the SET button, turn on the drives by pressing the power button on 
the front of the unit. Once the drives are ready, the port multiplier should “chirp” to 
indicate the process is complete. If instead of a chirp the Port Multipl\
ier 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 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 using the AC power switch on the rear, then set the dip 
switch to the desired RAID Mode.
3. 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.
After releasing the SET button, turn on the drives by pressing the power button on 
the front of the unit. Once the drives are ready,, the port multiplier should “chirp” 
to indicate the process is complete. If instead of a chirp the Port Mult\
iplier sounds 
a series of short beeps, an error has occurred during configuration of t\
he 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, 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.
