Picked these up to use along with some "Mini SAS 36 SFF-8087 to (4) SFF-8482 Connectors With SATA Power" for use in connecting 3x 3.5in HDDs to my HP Proliant DL380 G6 server that I had accidentally purchased. The server is configured to use 2.5in HDDs and due to using a hard-drive backplane there are no cables to route out of the front.
