Difference between Storage Pool and RAID Group ?

Hi,

A new VNX Storage Array has been set up by consultant.

He creates Storage Pool for SAS Disk and NL-SAS Disk. On the other and, for those FLARE SAS Disk, he creates as a RAID Group.

All of them (i.e. 2 Pools and 1 RAID Group) are presented to ESXi Host Cluster.

We just wonder what is the difference between Storage Pool and RAID Group. Is there any difference / benefit ?

Thanks

Yes there is quite a difference – take a look at the white papers dynamo referenced

If its just the first four disks that aren’t in the pool – they cant be since they are smaller than the others due to the OS and vault area being there

For FAST VP to work you need pool ed storage. For the WIL and RLP you still need a regular storage group and besides that, as Rainer pointed out, the first 4 disks cannot be in a pool. For all other drives you are free to choose.
