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.
