Hello, dear!

Have a nice day!


For the server accommodating the VRM node:

If the number of disks on the server is greater than 2, form RAID 10. If the number of disks on the server is 2, form RAID 1.

The configurations of compute nodes are as follows:

You are advised to use hard disks 1 and 2 to form RAID 1 for installing the host OS to improve storage reliability.

When setting the boot device in the host BIOS, set the first boot device to the disks that form the RAID 1 group.

If the host has multiple disks, you are advised to use all the hard disks except disks 1 and 2 to form a RAID 5 group.

If the customers have special requirements on RAID, adjust the configurations to suit their requirements.

NOTE:

The RAID controller cards on certain servers require that server disks must form RAID groups. Otherwise, the host OS cannot be installed. For details about the RAID controller card requirements, see the server product documentation.
