Half height 12+ port RAID card, does it exist?

[ninja6o4]

I have a 2U server with 12 drive bays that I'd like to completely populate. I intend to use 6TB Seagate enterprise SATA drives.

Does a 12 (or 16) port, half height RAID card exist? I am also contemplating a 4/8 port + expander but I'd like to reduce points of failure if I can.

I did find one model made by Areca (ARC-1880ixl-12) that fits the bill, but can't find any for sale here or on eBay. Just wondering if anyone else has some ideas..

There are cards with mini-SAS-HD connectors which can manage 16 drives:

Adaptec by PMC | Adaptec RAID Series 8 is an example.

Adaptec by PMC | Adaptec Series 7H HBAs is an HBA that can handle 16 drives in half-height.
