Hello. We want to configure from start a VSP, starting with Parity Group(s). What is the best recommended way. How many PGs. How to select the drives.
We have 3.2TB/6.2TB(SSD/FMC). 14D+2P or 6D+2P or 12D+2P. How that is selected. And, after that we would like to create two Pools. What are the recommendations for the new Pools. What is the right size of a DP-Volume etc.  Thanks

Hi Sudhir,

it depends on the machine type and the customers requirements:

is it  a 2U CBX (VSP G350, VSP E590, VSP E790)?

 Then it doesn`t matter from the perspective of redundnacy, whether you take 6D+2P, 12D+2P or 6D+2P.

In case of the big controllers, it is possible to install Parity Groups fully redundant, spreaded across four DBs verticaly. In this case, 6D+2P is the choice.

The bigger a Parity Group, the slower and bigger the drives are, the longer the rebuild will take in case of a broken drives. 

There are so many parameters in the game, there is no general recommendation covering all scenarios.

Hi Antonius.  Thanks for the insights.

Its a VSP-G800. We don't have big controllers as the box is a mid-segment, I guess.   How many Parity Groups do you recommend. Shall we make 3.2TB drives separate PG, and that for 4TB drives another PG.  Is only 2 PGs a good practice. We have another E-Series E1090H, and I see there are lots of PGs. So how many PGs we should have.  Please advise.  And, then how about Pools. What is good recommendation there.  Other VSP has two Pools. Best
