A big thumbs up for Nexenta Storage

OK I'm stuck at work for a few more minutes waiting for a job to finish so I'll throw out a bit of info regarding my newly built Nexenta storage platform. Based in part from sticker shock looking at Dell or HP low end storage devices as well as on the advice from Mike from over at IPHouse.net, I bought some Super Micro parts and built the storage cluster myself. I started with a 836E2-R800B 3U chassis just for housing the disks. I wonder if there is some kind of cheat sheet for Super Micro products because it seems confusing as hell.
