StoreVirtual sizing - Network RAID 5

[A.W.R]

Hi,

I am trying to understand the StoreVirtual capacity sizing. We have 3 Storevirtual P4330 each with 8 by 1TB disk drives in a hardware RAID 5 configuration providing 6.2TB usable space. If I put these into a network RAID 5 configuration I was expecting about 12TB usable storage as per the various sizers I have used. In reality I only get about 9 TB.

If anybody can advise if there are any paramters I need to consider it would be great.

Thanks

Andrew

Make sure you make the volumes thin porvisioned.

Also make sure you are using the volumes as repositories and not for lots of writes.

I have had previous posts on why you want to do this.

Let me know what happens once you change the volumes to thin.
