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
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.
God they’re so expensive now. I bought a 24-port backplane for $37 like 3 years ago and the same one is now $120
