On the forward version the SFF-8643 goes to the controller and the SATA ends to the drives; here the SATA ends go to the controller and the 8643 goes to the backplane. They are two separate SKUs, and ordering by \"where is my 8643\" gets it right every time.\u003c\/p\u003e\n\u003ch3\u003eCan I just flip the cable around and use it as a forward breakout?\u003c\/h3\u003e\n\u003cp\u003eWe do not recommend planning a build that way. The two cables are specified and sold separately for a reason; if your 8643 is on the host, order the forward version — it is the same price.\u003c\/p\u003e\n\u003ch3\u003eWill it work with SAS drives?\u003c\/h3\u003e\n\u003cp\u003eNo. The fan-out legs are 7-pin SATA connectors. SAS drives need SFF-8482 ends, which is a different assembly.\u003c\/p\u003e\n\u003ch3\u003eHow do I confirm my backplane takes four SATA into one 8643?\u003c\/h3\u003e\n\u003cp\u003eCount the SATA-equivalent ports the cage presents. If one 36-pin MiniSAS HD connector covers four bays, this is the cable. If it covers eight bays from two 8643 connectors, you need two cables and eight free SATA ports.\u003c\/p\u003e\n\u003ch3\u003eOnly three of four drives appear. Where do I look?\u003c\/h3\u003e\n\u003cp\u003eReseat the 8643 latch first, then check the fourth SATA leg at the controller. Swapping two legs tells you in seconds whether the fault follows the cable or stays with the drive bay.\u003c\/p\u003e\n\u003ch3\u003eDoes the length include the connectors?\u003c\/h3\u003e\n\u003cp\u003eNo. 75 cm is cable length from shell to shell; the connector bodies add a few centimetres at each end when you are measuring clearance inside a chassis.\u003c\/p\u003e\n\u003ch2\u003eIn the box\u003c\/h2\u003e\n\u003cul\u003e\u003cli\u003e1 × 4 × SATA to MiniSAS HD (SFF-8643) reverse breakout cable, 75 cm (SKU B0CHMB6WKX)\u003c\/li\u003e\u003c\/ul\u003e\n\u003cp\u003eEvery cable is continuity- and pinout-tested before it ships and carries a 24-month warranty.
