We recently acquired a PowerVault ME4024, with a mix of flash and 10k drives. We bought some SSDs to use them as storage and some (2x480GB) to create a SSD Cache.

I have created a read-cache disk group with these two drives but I'm not sure I have configured them correctly:

Pool A

• 8 SSDs in two RAID10 disk groups

Pool B

• 2 SSDs in a RAID0 read-cache disk group
• 8 10 SAS 10k disks in two RAID5 disk groups

I created the disks groups and some volumes, but I want to be sure the 10K disk groups are being optimized by the read-cache disk group.

Can you help me?
