Hi,
we recently bought a FAS3140mc storage and I wonder if it exists an efficient way to compute the size of a flexvol (we use the FAS3140mc in pure SAN mode, no CIFS/NFS access).
I do not use snapshots but I've understood that I must keep space for fractional reserve so I can't create a volume which have the same size that the LUNs it contains.
So, do you know a math formula which can help to size my volume ?
For example, if i create a Flexvol with 10 LUNs of 1 TB, should I create a volume of 10.5, 11 TB or any other size ?
Best regards,
Franck.
