Sure thing!

2 x Quad Core Xeon 5355

Infinihost III DDR HCA
2 x 143GB SAS 13k RPM disks for the metadata volume ( in a hardware
perc5 raid 1)

Dell PE1950
2 x Dual Core Xeon 5150

Infinihost III DDR HCA
3 x MD1000s w/1TB Drives
Each MD1000 is connected to a single perc5 and has two 6tb raid5 arrays.

Dell PE1950
2 x Dual Core Xeon 5130

Infinihost III DDR HCA

Each MD1000 is connected to a single perc6 and has two 4.4tb raid5
arrays.
IMPORTANT --
For a significant increase in read performance run this command on
every block device exported by the perc5/6. A wiki page on the Dell
perc5/md1000 combination could be very useful specifically for this
purpose, or perhaps some mention in the user manual. Am I able to
create wiki pages?
/sbin/blockdev --setra 16384
Thanks again!

We have a relatively small lustre setup (50TB) with infiniband as the

and 500MB/s writes from one client. I literally had to stand up and
leave the room. I was absolutely floored. I wanted to thank the
lustre
developers for their outstanding work and continued dedication to
supporting those (like myself) who can't afford a support contract.
Aaron,
thanks for the positive feedback. People always have time to
complain,
but far fewer take the time to report when things are going well, or
better than expected.
Can you please elaborate a bit on your system configuration (HCA,
SDR/DDR,
switch, CPUs, RAM, #OSS, #OSTs, etc) for reference.
Cheers, Andreas
