I'm also considering getting coraid EtherDrive -- www.coraid.com. The use
ATA over Ethernet (AoE), and have drivers for Linux 2.4/2.6 that will make
each drive appear a local drive. Basically you attach the Coraid server to a
GigE switch and all the computers attached are able to see the drives as
local drives.

How would GFS work under such an implementation (it's close to something
like the one GFS server you suggested). Will one still need to use iSCSI or

GNBD is about 4 years old.  It's worked for a long time.  Long before you
could get an iSCSI client for Linux.

Will iSCSI get to the point where GNBD is obsolete and is dropped?
