How to optimize the performance of your hardware RAIDLink to this anchor

For maximum performance, you can activate the cache of your SATA disks. After creating a virtual disk, the cache of SATA disks is disabled by default. Restore maximum performance by re-enabling the cache using rescue mode.

Note

This step can be performed on Dedibox servers equipped with a DELL PERC H200 RAID controller and SATA hard disk drives.

Boot your server into rescue mode using a 64-bit Ubuntu operating system.

Log into the server using the provided SSH credentials and run the following commands to re-enable the disk cache:

sudo su
echo 'deb http://linux.dell.com/repo/community/deb/latest /' | sudo tee -a  /etc/apt/sources.list.d/linux.dell.com.sources.list
apt-get update && apt-get install -y --force-yes srvadmin-base
service dataeng start
/opt/dell/srvadmin/sbin/omconfig storage vdisk  action=changepolicy controller=0 vdisk=0 diskcachepolicy=enabled
