In the event of a Data Mover failure, this unit takes over the <> function of the failed unit. The standby Data Mover does not contribute to <> the performance of the system and is not included in the processor, memory, <> or other components listed above. <> <> Server tuning: <> param ufs inoBlkHashSize=170669 (inode block hash size) <> param ufs inoHashTableSize=1218761 (inode hash table size) <> param ufs updateAccTime=0 (disable access-time updates) <> param nfs withoutCollector=1 (enable NFS-to-CPU thread affinity) <> param file prefetch=0 (disable DART read prefetch) <> param mkfsArgs dirType=DIR_COMPAT (Compatability mode directory style) <> param kernel maxStrToBeProc=16 (no. of network streams to process at once) <> param kernel outerLoop=8 (8 consecutive iterations of network packets processing) <> file initialize nodes=980000 dnlc=1056000 (no. of inodes, no. of dirctory name lookup cache entries) <> nfs start openfiles=722462 nfsd=4 (no. of open files and 4 NFS daemons) <> param ufs nFlushCyl=16 (no. of UxFS cylinder group blocks flush threads) <> param ufs nFlushDir=16 (no. of UxFS directory and indirect blocks flush threads) <> param ufs nFlushIno=16 (no. of UxFS inode blocks flush threads) <> ap msr write=0x880281 (P4 prefetch disable) <> <> Storage array notes: <> The storage array was configured into 38 RAID-0 groups of 3 spindles each (114 total disk spindles) <> The stripe size for all 38 RAID-0 LUNs was 8KB and each LUN was 30GB. <> The filesystem is built on a volume made by striping across all 38 LUNs <> on the CX500 storage array with an 8KB stripe size. <> The default UFS log of 64MB was used. The UFS log and OS shared the same 4+1 RAID-5 group. <> 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 in the event of <> 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 Aug 31 17:02:37 EDT 2004 by SPEC SFS97 ASCII Formatter Copyright (c) 1997-2004 Standard Performance Evaluation Corporation
