For testing do you even need to bother with RAID (or rather spending the money just to have RAID for testing)?
What I would do is try a P4000 VSA and something like the OpenFiler Virtual Appliance which can do NFS, CIFS or iSCSI then you'll have some hands-on with shared storage and you'll be a little wiser on where a NAS device may be more useful than a SAN, or not. One thing I noticed in one of your earlier posts is that you referred to being able to do SAN level replication - to what (if you only have one device)? Oh and the IOPS stuff I listed, I'd do that ASAP, I suspect it'll come back showing you have very low utilization in spite of the data volume but you do need the IOPS numbers. ~ Finally, powerful endpoint security that ISN'T a resource hog! ~ ~ <http://www.sunbeltsoftware.com/Business/VIPRE-Enterprise/> ~ --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com with the body: unsubscribe ntsysadmin
