3PAR minimum time for snapshot

Hi

 

What is the minimum time between two 3PAR Snapshot? (e.g. 30 minutes for P4000)

Do we have any document for this?

Re: 3PAR minimum time for snapshot

I do not think so there is a minimum timeframe as such. If you execute a CLI snap of a group of volumes and then issue the command again against the same group they will run serially as far as I know. I’m not why you would want snaps less than a few minutes apart, say 10 min but that is possible.

Hi,

 

Yes i think 2-10 minutes is okay.

Has it been tested and documented ?

Re: 3PAR minimum time for snapshot

As far as the array is concerned, I have not seen any minimum documented anywhere. The testing results would vary on factors like your environment, type of snapshot, nature of data etc....

Re: 3PAR minimum time for snapshot

If you are using "createsv -ro", it mentions it blocks the host I/O, unless -noblock is used.

 

Otherwise you can create them as fast as you can type.  ;-)
