Intel's www.intel.com/go/ESSA offers a server configuration recipe that was tested with ESXi being installed on a single, SATA hard-drive.
My question is this: what RAID options are available for a validated solution?
I've been following up with the Intel ESAA Program about this but am still awaiting a reply.
"We (Intel) only support SAS Hardware RAID. A SATA drive is supported in this controller. You will need two drives min for RAID."
