Also, I spent a fair amount of time measuring file i/o over nfs, and generally found it 1/8 to 1/10 as fast as block-level network access. I dare you to measure and compare. Even with some serious tweaking of parameters, or switching to udp instead of tcp, nfs is much slower than block-level access. In both cases I was running the i/o across a gigabit ethernet.
OK, but how do I use a SAN to replace NFS? If I have multiple computers, doesn't each computer have to be assigned it own partitions on the SAN, so that the SAN doesn't enable file sharing across computers, only disk sharing? I haven't looked carefully into SANs for exactly that reason - or have I been wrong? I'd be interested in the speed improvement if the files could be shared.
