DELL Poweredge 750 with SATA raid controller is very slow

Hi

I have a few DELL Poweredge 750 with a Sata Raidcontroller. We use 2x120GB disks in a raid1 configuration.

As an operating system we use Centos 3.3.

As soon we have some disk usage on the server, the IO value gos up and the server is getting very slow.

Does anybody have the same server? If yes, is there a solution for this problem?

Thanks
Michael
