Recommendation for Raid Groups for lots of disk

Hi -

in our environment we have a 6280 san and we use Commvault to back data from the 6280 to our v6210. We recently purchased a lot of 2TB disk that are not assigned to any aggrs yet and I am anxious to get my mits on those disks and start re-engineering our current setup and was curious what raid group size I should do. I think (not 100% sure) that Commvault requires at least 7 disks per raid group.

My assumption - is more spindles the better ? As the i/o this helps the i/o reads.

Anyhow I have a 132 spare 2tb disks on controller a.

and 156 spare 2tb disks on controller b. these disks are right sized at 1.62 TB

and these sans are on 10GbE network. So what are your guys thoughts for best performance and usage of disk for nice sized aggrs as I would create 5tb volums with qtrees and cifs share for Commvault to write the data to.

Ah, sorry - now I see what's going on!

8.1.x - 162TB limit is across the board the same for all 6200 series boxes (& 6070 & 6080)

8.0.x - 100TB limit for 6240 & 6280, but only 70TB for 6210!

So in fact you are looking at recommended max aggregate layout of:

- 40 spindles = 2x 20-spindles RG
