My raid drives consume 11w per disk at maximum load and i have more than 400w left on my power supply. Thanks for the clarification I will have the hba card so that will be ok, 5satas port is ok with an al-x motherboard, the problem might be the number of pci ports and the vt-d compatibility. 20

Finding a vt-d compatible motherboard (with real compatibility) is a pain, also i need a lot of pci-express ports for controlers cards/gpu etc, and i would need at least 9 sata ports. I'm not really willing to spend money on a motherboard i will drop in 4months top (kubylake) and not sure it would

Okay, seems i have a lot of reading todo on zfs now. It appears it is possible to import zfs pool even if the host os died. So if it is possible to import the pool from a totally different os (but still linux)as long as it supports linux file system and zfs that should do it. 2016-01-25 12:47 GMT+
