Hi,

We have eight ps6110 arrays.  First four is a mix of SSD(7 drives each 400GB) and 10K SAS(17 drives each 600GB) and another 4 is all 7.2K SAS (each drive is 3TB).

I have few questions

1) Which is the recommended raid in such a case?

2) Do we need to isolate arrays into 2 or more groups since we have different types of disks?

3) If we make one big group with one pool, will the performance degrade?

Thanks

Paras,
