Am I stuck with AHCI?


Recommended Posts

Just had a server go down due to motherboard (or CPU) troubles. It was old.

 

I bought an Asus Z270E Gaming board and Kaby Lake CPU and upgraded to unRAID 6 on that server.  Now I think I am having the AHCI driver issue where file transfers fluctuate between full rate (100+ MB/s) and zero throughout.  Moving loads of large files with rsync from reiser disks to new XFS disks, so it is not a network issue.

 

In the Asus' BIOS I have only AHCI or Intel RST (RAID) options for the built-in SATA ports.  Is there a way to use another driver for the AHCI ports or do I just need to find another PERC controller and not use the motherboard ports?

 

I'd like to use the motherboard ports as I only have one more PCIe slot available, and it's an x4 instead of the full x8 needed by the PERCs.

 

Any thoughts?
