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
The one on the right looks like a 14 pin molex connector. You can buy the plug by itself and make a connector, but finding the pinout is going to be a bitch. As for the one on top, it looks like maybe a USB2.0 motherboard socket.
The one at the top could also be a connector for a serial port for debugging or so.
+1 on that. The User’s guide of a similar device (source) mentions a 10-pin CPLD connector Reserved for IBM use
As often with IBM, everything is proprietary 😅
If it can’t be found online, could start poking with a multimeter.
