Ok so I am a newbie but also I have could not find a single thing anywhere about this and I really don't want to use windows 2003 R3 to do this. Here is the environment;

(NEW) DELL 1950 III with SAS Card - Intel 2.0 GHz Quad Core
(NEW) DELL Powervault RAID MDS3000 with Clustering SAS card
Centos 5.2 x64

According to DELL you can hook up to (2) head nodes directly to the MDS3000. The controllers in the MDS3000 act as a clustering switches so that they can both access the shared storage. Now I know nothing about GFS or clustering in Linux and if anyone has a few pointers on this please let me know. My thought was that I would need to configure the RAID (MDS3000) with GFS so that (2) servers could cluster the data stored on the RAID. If I don't need to this then great. Thanks in advance for your input.
