Hardware for RH Cluster Manager

[danci agenda si]

Hello,

I'm in the process of choosing the hardware to build a two node cluster 
using RedHat Cluster Manager.

Since there are not a lot of certified systems, I wonder if anyone has any 
experience with other hardware - my main concern is the (shared) storage.

I'm investigating using an IBM DS400 Fibre Channel storage system - my 
preliminary tests show that it is possible to access one logical drive 
from two servers - so I guess it should work fine with the RH Cluster 
Manager.

Any comments, ideas, suggestions?

 Thanks, Danilo
