Hello all,

I just need to provision FAST Cache for my array (CX4-480).

I have 4 available disks that I split into two buses excluding 0_0.

Documents "EMC FAST Cache, A Detailed Review" and emc251589 are very useful, but I need advise whether I configure my mirror(s) as 2 sets of 2 disks or 1 set of 4.

What would be a better setup and why if you can answer.

I appreciate your help.
