NOTE:

Storage controllers must be compatible with the server connected.

More than four disk drives must be installed.

All hard drives within a RAID array should be of the same capacity and rotation speed.

To configure a large-capacity RAID array, it is recommended to configure in RAID 6 or RAID 60 in

order to minimize the risk of becoming multiple hard drives failure during the RAID rebuilding process.

It is recommended to set RAID array configuration drives less than eight in order to minimize the risk

of becoming multiple hard drives failure.

Any of RAID arrays cannot be used as a boot device.
