Just bought an ex-lease server and it came with a hardware RAID controller installed, I have no need for it as I am using unRAID and therefore have replaced it with an HBA.

 

Was confirmed working by the seller of the server, I haven't tested it. I believe it supports SAS 6GB/s (two 8087 ports), has 512MB cache memory and a back-up battery installed, more info can be found at this link.

 

I have looked at the prices they are selling on eBay for and decided to price it accordingly, and would be happy with $45 plus shipping or buyer can pick up in Palmerston North.
