Storage array notes:
The storage array was configured into 43 RAID-0 groups of 3 spindles each (129 total disk spindles, log+data)
Each RAID group was striped with an 8KB size stripe. Two of the 43 LUN
groups were used for the ufs logs. Each of the 41 file data LUNs was 30 GB.
The ufs logs were 2GB each.
The storage array has dual storage processor units that work as
an active-active failover pair. The mirrored write cache is backed up
with a battery unit capable of saving the write cache to disk prior to
a power failure. In the event of a storage array failure, the second
storage processor unit is capable of saving all state that was managed
by the first (and vise-versa), even with a simultaneous power failure.
When one of the storage processors or battery units are off-line, the
system turns off the write cache and writes directly to disk before
acknowledging any write operations.
The length of time the battery can support the retention of data is 2
minutes - that is sufficient to write all necessary data twice.
Storage processor A could have written 99% of its memory to disk and
then fail. In that case storage processor B has enough battery to
store its copy of A's data as well as its own.
