Cipher Chain Module
The Cipher hardware in the R14CCES is activated by either powering up the
unit or pressing the Cipher Reset button with the Cipher Key inserted. Without activating the Cipher hardware, no drives in the Raid Rack will be visible 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 button pressed while the key is inserted for the unit to resume normal operation. 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 encrypted data be removed from the Raid Rack and installed elsewhere, it will appear to be completely blank with no partition table or file system.
Port Multiplier Compatibility
The R14HPCCES unit only supports configuring the drives in RAID configura- 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 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.
Hot Swapping drives
The R14HPCCES 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.
