iSCSI vs. Fibre Channel vs. Direct Attached Disks?

Posted by Cliff on Thursday December 30, 2004 @11:45AM from the it's-all-about-the-performance dept.

mrscott asks: "Does anyone have any good, simple benchmarks about iSCSI performance in a SAN as it relates to fibre channel and direct attached storage? There's a lot of information out there about iSCSI TCP offload adapters that improve performance, but it's still hard to get a handle on even those stats without the original numbers for comparison. We're considering an iSCSI solution from Lefthand networks, but finding independent (and reasonably simple) numbers has proven somewhat difficult, even with the awesome power of Google behind me."

but, but... iSCSI has nothing to do with Ethernet.
iSCSI is an IP protocol, and it could be running
over anything that sends datagrams. FiDDI, HiPPI,
Myrinet, la la la...

If you dislike iSCSI over Ethernet (and frankly,
it's only interesting in low-performance cases where
IP routing is important for WAN access to NAS,
so I can understand your aversion), don't use it.
But keep iSCSI in your toolkit. The interoperability
and the option to route is extremely valuable.
