The nodes in my cluster have dual Gig-E nics (tigon3). I'm pondering
the installation of a second gigE switch to attach them all with a
private storage network, and run it with jumbo frames. Do you think
I'd see a significant performance increase with PVFS in this
configuration?
We're currently running the nodes with standard 1500 byte frames as
the nodes are sitting on a shared network with the rest of our group
infrastructure.
I'm also curious if folks have experimented with the effects of the
TCP segment offload stuff that is available on these NICs.
thanks,
