NVMe U.2 drives in machines with out U.2 backplanes

 I just discovered these and figured it worth the share.

NVMe drives that are in 2.5" hard drive form factor (versus the more familiar M.2 "gum stick" variety), look just like a normal SAS hard drive.  However the pinout is slightly different, and one needs to have different backplane and connections to the PCIe bus than SAS.  IE one can not take a server physically configured for SAS/SATA drives and utilize these U.2 drives. 

This is where this adapter comes in.  Mount the drive to the PCIe card, plug the card into the computer, and one can now utilize that hard drive.  Another feature of this specific card is one could use a normal 2.5" SATA hard drive on this card as well.  One just needs to feed a SATA cable to the card.  Both are very handy options to for instance adding a single 2.5" drive to a machine that is doesn't have any extra drive bays, or the bays are configured for 3.5".
