I guess you have two gigabit nics bonded in mode 6 and not two 1GB nics?
(B-Bytes, b-bits) The max aggregate throughput could be about 200MBps
out of the 2 bonded nics. I think the mode 0 bonding works only with
cisco etherchannel or something similar on the switch side. Same with
the FC
MD3000 series doesn't seem to have raid 6 support, which could be very
useful with lots of sata drives.
Also MD3000i doesn't specify LACP support for the dual or quad Ethernet
ports on the enclosure. But
a pe1950 + perc 6 with MD1000 has raid 6 support and the OSS can benefit
from good ethernet
Hi,
The storage server that served Lustre had a drive
failure on the 3ware 9650 raid6 array and it seemed to
rebuild fine. But almost all volumes in that array seems to have
filesystem corruption. The partitions with OS
didn't boot after i did the fsck as it deleted lots of

Hi,
Postmark is a good benchmark for small file peformance. I have tried
it with gfs and lustre before for comparison. Lustre doesn't shine well in
that benchmark. But when the file size is set a little high, lustre does pick
up quite a bit.
settings for very small files, the results are worse than nfs.
Lustre could still be a good choice for mail servers that use mbox, but
for maildir i am not so sure.

Hi,
Please read the i/o tunables in the proc section in the lustre
manual.
I tried that with the postmark benchmark to test improvement and there
was some improvement after trying the suggestions in the Lustre manual.
