[Linux-cluster] RHCS Coraid/ATAoe compatibility

[Franco Martin Bladilo <bladilo rice edu>]

We are considering the option to build a 4 node HA cluster using RHCS 
and Coraid products (SR1521). ATAoE seems to be the most cost effective 
solution for our case and I was wondering if there are any comments/ 
feedback for such configuration.
Is the quorum partition issue (shared concurrent access) still a 
limitation for these appliances? Can these "service" partitions be 
formatted using GFS? Any other workarounds?

Thanks in advance,

Franco.
