Help needed with some cables

[Oedzes]

Hello everyone,

 

After almost finishing my first Unraid DIY server, I cannot help but ask for your help.

 

I am using a silverstone cs381 case.

(https://www.silverstonetek.com/product.php?pid=861&area=en)

 

Now this case has a backplane with a Mini-SAS SFF-8643 connection, well I had bought a cable on Amazon and when both: mobo and Unraid did not detect the hdds, I found out after some googling that the cables have a direction: Noob

 

Since I plan to run my system maps, plex transcoding / metadata and NZBGet unpacking on ssd drives, I am running out of SATA connections on the motherboard.

So I bought a sata controller over the Internet (it flashed)

since this card has a Mini-SAS SFF-8087 connection, I thought to connect the card to the backplane of the silverstone case and connect the ssd's to the sata ports on the mobo, or do you think I should do it the other way around?

 

And to avoid making another stupid mistake, which cables should I use to connect the backplane to the sata card?

It seems like i can order these also in 2 directions:

All your help is greatly appreciated!

Only breakout cables (miniSAS to SATA or vice versa) have a direction, forward or reverse, miniSAS to miniSAS cables work in any direction.
