ZFS on Linux vs. LSI CacheCade: quick sysbench

Quick shot on one of our servers (2 x E5-2667 v2 @ 3.30GHz, 256GB RAM, 6 x HGST HUS156060VLS600 15K SAS drives, 2 x mirrored 80GB Intel DC S3500 as cache for both tests)

Disk access is done using a BBU backed LSI is a LSI MegaRAID SAS 9271-4i utilizing both SSDs at RAID1 as R/W cache and a IBM ServeRAID M1015 cross flashed to LSI 9211-8i in IT mode for the ZFS tests.

sysbench was using a 256MB and a 16GB testfile, test visualization is done with slightly modified version of tsuna’s sysbench-tools (needed to remove the --file-extra-flags=direct param in during zfs tests, also just one test file instead of 64)
