The goal was to measure performance as close to out <> of the box (default tunings) as possible. <> <> Server tuning: <> net.core.rmem_max=1048576 <> net.core.wmem_max=1048576 <> net.core.rmem_default=1048576 <> net.core.wmem_default=1048576 <> vm.min_free_kbytes=40960 <> vm.dirty_background_ratio=1 <> vm.dirty_expire_centisecs=1 <> vm.dirty_writeback_centisecs=99 <> vm.dirty_ratio=10 <> <> Each EXT3 filesystem was created, using default parameters, one on <> a LUN on AX100 and another on a LUN on AX150 for fs1, and fs2 <> accordingly. <> <> Each array had 2 Fibre Channel connections to the server although <> only one connection was enabled. <> <> Storage array notes: <> Each of the arrays, AX100 and AX150 contained 12 disks that were <> configured as (10+1) RAID-5 groups with 64KB RAID stripe size. The <> 12th disk was configured as hot spare. Each RAID group was binded in <> a single LUN on each array. Each file system was configured on one <> LUN: fs1 on AX1500 and fs2 on AX100. <> The storage arrays have 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 processor failure, <> the second storage processor unit is capable of saving all state that <> was managed by the first (and vice-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 Wed Mar 19 09:53:48 EDT 2008 by SPEC SFS97 ASCII Formatter Copyright (c) 1997-2008 Standard Performance Evaluation Corporation
