Configuring RAID on the Server

Redundant array of independent disks (RAID) implementations provide increased performance and data integrity across the available disk space in the server. By mirroring data across drives, most RAID levels can tolerate disk failures. Additionally, RAID configurations enable you to designate one or more hot spares. A hot spare is an unused drive on which the data on a failed drive can be automatically duplicated.

RAID configuration can be done before installing the operating system, and after the operating system is installed.

  • Before you install the operating system, you can use the BIOS utilities to configure RAID. This is a necessary step that must be completed before installing the operating system. For details, refer to your hardware installation guide.


    Caution  -  These procedures erase all data on the disk, including the operating system.

  • After the operating system is installed, you can use the following tools to configure and modify RAID configurations. However this erases all the data on the affected drives, including the OS. If you change the RAID configuration on a boot drive, you must reinstall the OS.
