MD3220 and Md1220 - Questions about SSD Cache, High Performance Tier, and sizing disk groups

This question has been answered by DELL-Josh Cr

I am migrating to an MD3220 and MD1220 which has the SSD cache and high-performance tier feature keys installed and enabled. I have 6 x 200 GB SLC SSD SAS drives and 24 x 900GB SAS HDDs in the MD3220, MD1220.

When I create the SSD Cache, should I assign all 6 SSDs to the cache? For maximum performance is it best to create 1 large RAID-10 disk group then create smaller virtual disks, making sure “Use SSD cache” is enabled?

Thank you very much!
