Thanks for the advise...but if we use the Hardware RAID then what is the
purpose of using glusterfs ?? We don't want to use HW RAID and want to
leverage the gluster replication...
If we use the HW RAID that means it will create another overhead (First HW
RAID replication and second glusterfs replication)...
