Thanks, vuzzini.
We stayed with the deprecated 29320LPE as the 2120S physically would not fit. The 29320LPE is working at the moment.
We're starting to look for recommendations on a PCIe 1x SCSI controller with an external 68-pin VHDCI connector.
The only device on this controller at the moment is a Quantum LTO 3 tape drive.
Thanks again,
