This is a part from an IBM server dated 2008 that I want to reuse in my new computer. It essentially converts from 1 SAS port to 4 SATA ports. I’ll use the raid card to connect to it via SAS, but I do not know what the power port is and what the connector on the top is either
Looks like a usb, and a molex power connector. You’d have to break out a multimeter to figure out what’s active and what’s a ground though, and then have to bit bang your way to figure out what each connection does.
