Don't Sink Your IP SAN: Page 6 of 16

On the plus side, we were impressed with the Pro/1000 T's CPU utilization scores, which were neck-and-neck with Adaptec's across the board.

The archenemy of iSCSI is Fibre Channel, which comes in 1-Gbps and 2-Gbps flavors, but iSCSI's ace is its use of Ethernet and IP. This benefits you in two ways: First, price; Ethernet ports are comparatively inexpensive. Second, Ethernet is well-understood while Fibre Channel requires a significant knowledge investment. Another plus for iSCSI is its ability to connect via WAN links. Your application's latency sensitivity will affect how big (that is, expensive) a pipe you'll need, but keeping your SAN safely tucked away in your data center while servicing remote locations is a big draw.

Of course, there's a reason Fibre Channel has been holding off iSCSI--raw speed. With a top end twice that of current Ethernet/iSCSI, shops with heavy storage loads will likely stick with Fibre Channel for now.
