Hyper-V Lab - SAS Storage

I have 2 small, standalone Hyper-V labs (two locations) starved for storage, that I'd like to expand.  

I have twelve 1-TB SAS drives that were used for a temporary project, which are now at my disposal.

I'd like to re-use these with my Hyper-V farms.  I was looking at SAS JBOD enclosures, but I want to make sure I understand the requirements for what I want to achieve.

I want this storage compatible with current GEN Hyper-V, and want my VHDs reasonably fast and safe (from drive failures).

Do I need 2 JBOD enclosures for each location, or just one?

Assuming I'm looking at "Provide your Own Drive" solutions, what specifications or features do I need to make sure I'm buying?

Thanks!
