3rd Party Array LUNs/NetApp Aggregates

Hello,

We are virtualizing an EMC Clariion SSD array with our NetApp v3240.   On the Clariion, all disks are in a single Clariion raid group and the raid group is carved into 16 LUNS.    The Clariion LUNs are presented to our Netapp v3240.   We then created a NetApp aggregate made up of the Clariion LUNs.   The NetApp aggregate is made up of two 8 disk raid groups. 

Is it OK to have a 2 raid group NetApp aggregate that is made up of LUNs from a single raid group on a 3rd party array?   

The best practices guide says to use a dedicated array raid group, which we are doing, but doesnt appear to mention anything about how those luns should be destributed within the NetApp aggregate (single raid group, multiple, doesnt matter?).

Thanks,

-J

Ah yes I see. My words may have been twisted around- right idea, wrong phrase.

The LUNs from the single array RAID group can and will be split into multiple Netapp RG's in the same aggr. The RG size does not have to match the array LUN count.

However, as Dan states below, with spinning disks, you may run into performance issues with disk contention. But with SSD you should be ok.

Thanks!
