Hi Josy

GlusterFS version I use:

glusterfs 3.0.3 built on Mar 16 2010 18:10:30
Repository revision: v3.0.2-41-g029062c

on Linux Debian 2.6.26-2-xen-amd64
3 servers have 8 GB RAM (the ones which run apache & plesk).
4GB for the phy server and 4 GB for the rest ( I guess it is enough)

benchmarks:
