I am looking to end up having a tiered SSD/HDD array in a "RAID 10" type of setup. I am wondering if I am going to have to have dual port SAS drives to make my implementation work.
I am looking to have two 2012R2 Storage Spaces servers hooked to one 12 bay JBOD enclosure through SAS. To have these two servers manage this enclosure so I can take 1 server down at a time, am I going to have to have dual port SAS over SATA?
If I do have to go with dual port SAS drives, can I put SATA SSDs in the two servers themselves to act as a Write Back Cache? As I can't afford dual port SAS SSDs for my implementation.
