I recently purchased an IBM BladeCenter E chassis with HS21 blades. I'd like to build a SAN so the HS21 blades will have more storage space.
From everything I've read, iSCSI seems to be the best choice for a cheap SAN. I can't afford Fibre Channel, and ATA over Ethernet means I can't use the network for TCP/IP at the same time, right?
The HS21 blades have Broadcom NICs that are also iSCSI Host Bus Adapters. I'd like to use my Linux desktop as the iSCSI target.
I haven't used iSCSI with Linux before, what are the choices? I've seen a few kernel modules and various userspace tools, but I haven't been able to figure out which is the most used, best supported, etc.
