By compute node if you mean a node which is a part of a compute cluster(parallel computing) then it would be a very bad idea.<br>I tried it on my 16 node cluster using both IB and ethernet.It always showed that nodes which were running OSS were over utilized and they were since user's reported this fact.<br>
But in my case there was no raid controller.I was using a partition of the OS disk.<br>You may very well try it in experimental environment and run some benchmarking test's for both lustre(using compute node OSS and then other OSS) and lmbench , do it mix and match and compare the results.If you are successful then please repost the results.<br>

Hi,<br>
<br>
<br>
Do you see any problem in having each compute node, within a grid,<br>
acting as an OSS server via the separate IB channel on the fabric? My<br>
compute nodes have built-in raid controllers.<br>
Any feedback and comments are really appreciated.<br>
Regards,<br>
