We do that here at NPS without much trouble - anymore ;)

One thing to watch: if you are using opensm for your subnet manager and
the latest kernels for lustre (1.8.4/5 or 2.0) you need a newer opensm
than is on the CentOS 5.5 disks. Get the one from the updates. It seems
there was a change in the ibsrp kernel module that made it incompatible
with opensm on the same disk.

Subject: [Lustre-discuss] IB storage as an OST target


Anybody had any experience using an IB based storage
target as an OST?

Apart from the obvious issue of separating the IB SAN(SRP/SER)
storage traffic from the Lustre traffic are there any issues?

What about failover?
