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. =============================================================================== Generated on Tue Apr 29 16:24:55 EDT 2003 by SPEC SFS97 ASCII Formatter Copyright (c) 1997-2002 Standard Performance Evaluation Corporation
