You got me. I just double checked. 16GB is the limit. You're right. >What do you mean by "JBOD support"? Disable RAID in the systems BIOS >setup, put ZFS on AHCI drives ... Activating JBOD deactivates the B120i raid controller. Unfortnately the temperature sensor is somehow controlled by the raid controller. So enabling JBOD technically works, but the machine is a lot louder than with enabled raid. As a workaround I've built 4 raid arrays with one disk each. It works, but it doesn't feel right to me. It's my home file server sitting basically next to my monitor. In an office environment, you probably don't care about the noise so much.
