CAUTION: My R715 uses SFF-8087 - and these will NOT work!
The cables are quality made - at least from the outside. I cannot use them, however, as I require SFF-8087 cables.
I did not realize these were not SFF-8087 cables, because I read they are compatible with Dell PowerEdge R715. They might be, I don't know - but they're NOT compatible with the three R715s I have. Each server has a drive backplane using SF-8087 connectors, as do the H700i RAID cards which go with them.
Perhaps Dell changed the connectors mid-cycle for the R715, or maybe someone mixed up what an SFF-8087 and SFF-8643 are. I don't know.
I am now in a time crunch because I assumed, my bad, that being these cables are stated to work with R715, that they were in fact the correct cables. The length is correct, however the connectors are not.
