Using Lenovo SA120 for JBOD SATA Storage Expansion

The Lenovo SA120 is a good, small, 2U DAS/JBOD 6Gbps SAS enclosure. Since the Xeon-D systems ship with basically everything I need onboard, I’m planning on moving my 3ware 9750-4i4e card to it, going down to a 1U chassis, then connecting all my disks thru this enclosure.

Power usage

I measured power usage with no drives attached, enclosure connected using a single SFF-8088 cable to the controller, booted:


Fan control

The fans can be controlled over serial with the provided RJ-11 to RS-232 cable. The settings are required after power cycle; they do not persist.
