Raid Controller doesn't detect drives

[kds_by_dk]

Hi everyone,

i'm currently failing at building a Small Office Server for my friend.

 

The raid controller cant find any drive.

 

The controller has two mini-SAS HD SFF8643 connectors and I'm using a mini-SAS to 4x SATA adapter to connect the drives.

 

Steps i tried:

• reboot 
• connected the drives to the MB - they show up in MB BIOS
• connected other known good drives to the raid controller
• changed mini-SAS port on the controller
• used different SATA connectors from the mini-SAS to SATA adapter
• pulled the raid controller out, booted the system, and put it back.

 

System specs:

• Intel Xeon E5-2620v4
• ASUS Z10PA-U8 Motherboard
• Intel RS3WC080 Raid Controller
• 16 GB KIngston regECC
• 2x Samsung SSD 860 Pro 1TB
• 500W PSU

All the components are new.

 

 

As far as i can tell, all the components should be compatible with each other, but currently by guess is that there is some incompatibility between the controller, mini-SAS to SATA and drives.

 

Any help is appreciated.
