Hello zfs-discuss,
Server is v440, Solaris 10U2 + patches. Each test repeated at least two times
and two results posted. Server connected with dual-ported FC card with
MPxIO using FC-AL (DAS).
1. 3510, RAID-10 using 24 disks from two enclosures, random
optimization, 32KB stripe width, write-back, one LUN
1.1 filebench/varmail for 60s
a. ZFS on top of LUN, atime=off
IO Summary: 490054 ops 8101.6 ops/s, (1246/1247 r/w) 39.9mb/s,

303us cpu/op, 6.1ms latency
b. ZFS on top of LUN, atime=off
WRITE CACHE OFF (write-thru)
IO Summary: 281048 ops 4647.0 ops/s, (715/715 r/w) 22.8mb/s, 298us
cpu/op, 10.7ms latency
IO Summary: 282200 ops 4665.3 ops/s, (718/718 r/w) 23.0mb/s, 298us

cpu/op, 7.9ms latency
d. UFS on top of LUN, noatime, maxcontig set to 48,
WRITE CACHE OFF (write-thru)
IO Summary: 148825 ops 2460.0 ops/s, (378/379 r/w) 12.1mb/s, 772us

IO Summary: 151152 ops 2498.4 ops/s, (384/385 r/w) 12.4mb/s, 758us
cpu/op, 20.5ms latency
2. 3510, 2x (4x RAID-0(3disks)), 32KB stripe width,
random optimization, write back. 4 R0 groups are in one enclosure
and assigned to primary controller then another 4 R0 groups are in other
enclosure
and assigned to secondary controller. Then RAID-10 is created with
mirror groups between controllers. 24x disks total as in #1.
