Opensource NAS/SAN Software/Distros

[Mabrito]

Working on setting up a a 2 host Hyper V setup for a lab environment. Have a third server sitting around that will make a good central storage pool for these two hosts.

I know theres a few Opensource SAN/NAS distributions out there. Just need iSCSI emulation in it. Whats the best/good options out there to accomplish this?

I like Omni-OS with Napp-it and FreeNas myself. Both work decently well.
