ISCSI vs. FC performance: A closer look:

What weighs more: one pound of bricks or one pound of Featherslinks? Which is faster: 2 Gb FC or 1 Gb Ethernet? Hint: Both questions have the same answer.

A very interesting post from Tony Asaro. I haven't yet had any experience with iSCSI, so I'm really not in a position to have much of an opinion. My git tells me that iSCSI will inherently have more latency than fibre - simply because you're passing a disk control protocol over a networking protocol, rather than over the bare metal/silicon.

Of course, I'm open to be proven wrong - and quite look forward to playing with this tech at some point...
