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 cpu/gpu type power connector. Even if its a standard plug does not mean its a standard pin out ! Craft computing on YouTube had what looked like a standard plug in his server but it had a 12volt and ground switched, so would have caused some real damage
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
That sounds like more trouble than it’s worth. You can get a SAS to SATA breakout cable for < $20 on Amazon.
Absolutely this. Save trouble.
If absolutely in need of a backplane, look for old chassis parts from super micro on eBay.
I actually worked on the team that designed these! If I recall correctly, the top connector is for the motherboard BMC. It should work fine without being connected. The right hand side as others said is power.
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.
