Raid Drive Options - Sun Microsystems Sun Fire X4450 Installation Manual

The system will have the preinstalled OS on HDD0. When the Windows Server 2003
R2 OS installation has been completed, the option to upgrade your single-disk OS to
a mirrored RAID solution is available.
The configuration procedure is different for each supported controller card. For
example, a Sun StorageTek HBA card has many more options for RAID
configuration than an LSI HBA card. Configure the RAID depending on your needs
as shown in
Note – Configuring the Sun Fire X4450 server RAID is optional, by default the
preinstalled Windows Server 2003 R2 image is configured in a non-RAID
configuration. If anything other than a basic Mirror RAID is required, it is
recommended to perform a fresh install of the Windows Server 2003 R2 OS (or other
OS) in the desired RAID configuration.
