A: Technical Specifications

Environmental Specifications

Table A-2 lists the environmental specifications of the system.

Optional Solid State Disk Parameters

Table A-3 shows the basic operating parameters of the optional solid state disks available with the

Octane III systems. Note that MLC drives used beyond the capacity of their total projected write

life will not be replaced under warranty. STEC drives are warranted for three years regardless of

the number of writes. Both the MLC and STEC drives use a volatile write cache and are subject

to data loss during a power failure; this could cause XFS file system corruption and require file

repairs.
