General Information
For general information regarding the IBM SerialRAID Adapter, RAID technology and
SSA loops, see the
IBM SerialRAID Adapter: Installation and User's Guide
.
The IBM SerialRAID Adapter also contains array management software that provides
RAID-5 functions to control the arrays of the RAID system. An array can have from 3 to
16 member disk drives and is handled as one large disk drive by the operating system.
The array management software translates requests to the single large disk into
requests to the individual member disk drives. Configuration software is available that
allows the user to define which disk drives in the loop, if any, are to be included in an
array.
Up to three adapters can be present in one system unit. For performance reasons it is
recommended that they are all placed on the same bus.
A module on the IBM SerialRAID Adapter contains a lithium battery.
CAUTION:
A lithium battery can cause fire, explosion, or a severe burn. Do not recharge,
disassemble, heat above 100°C (212°F), solder directly to the cell, incinerate, or
expose cell contents to water. Keep away from children. Replace only with the
part number specified with your system. Use of another battery might present a
risk of fire or explosion.
The battery connector is polarized; do not try to reverse the polarity.
Dispose of the battery according to local regulations.
