old equalLogic hardware, need help on getting started

Hello, 

Total storage newbie here. I've messed with iSCSI before via FreeNAS in an attempt to get some shared storage up for a test Windows cluster, that's about it. Where I work there is some retired equalLogic hardware laying around that I'd like to get up and running purely for testing and learning. Below are some pics of the hardware. I have no idea where to start, googling tutorials for enterprise hardware is a little tough. I'm looking to attach my hosts directly to the hardware via dedicated NICs.

Thanks in advance for any help getting me started.
