They look like SFF8087 but they are not as wide, and do not fit the standard Mini-SAS ports on most raid cards. I don't think they are even SFF8088 which usually have a squarish metal connector.
My guess is they are some proprietary design for a particular device, and there's now a whole bunch of them spare filtering into the market. You can see them on ebay as well. Some sellers actually list them as 26pin.
