You can have both SAS and SATA, they just can't be in the same virtual disk. If you want to have a hot spare for the SSDs then you will need to add another disk. SSD, SAS, and SATA cannot be mixed in a virtual disk, so the SAS spindle hot spare cannot be used as a hot spare for either SAS or SATA SSDs.

Excellent information thanks. What about the speed aspect? Does anyone have a sense of the difference in speed for:
1. existing RAID 6 with (10) 600gb 15k SAS (in shared environment)
2. new RAID 1 with (2) 800gb SATA SSD (dedicated to a few light-use databases)
3. new RAID 1 with (2) 480gb SAS SSD (dedicated to a few light-use databases)
How would I find this information?
