2.1 MegaRAID Primary Storage
In the MegaRAID primary storage configuration, the Windows OS is installed on virtual drives provided by the
MegaRAID controller. The MegaRAID controllers (6Gb/s and 12Gb/s) include pre-boot configuration utilities
(WebBIOS™ and Ctrl-R) that creates the virtual drive before the installation of the Windows OS starts.
To install the Windows OS, prepare a USB flash drive, CD-ROM or diskette, as appropriate, with the MegaRAID driver.
The driver is distributed in a series of nested compressed files. Use an existing Windows device to extract the files for
the driver-loading device (USB, CD-ROM, or diskette) by using the appropriate Windows driver. Only two driver choices
exist across the supported Windows versions: one for 32-bit systems or one for 64-bit systems.
2.1.1 Storage Configuration
The procedures in this section describe how to create the virtual drive used for the Windows OS. You can add other
virtual drives to the running OS after the Windows OS has been installed. The MegaRAID preboot BIOS utilities, such as
WebBIOS (for 6Gb/s controllers) and Ctrl-R (for 12Gb/s controllers) that create the virtual disk for the Windows OS are
accessible during the power-on self-test (POST) part of the bootup process.
Refer to the MegaRAID SAS Software User Guide or the 12Gb/s MegaRAID® SAS Software User Guide for more information
about the WebBIOS configuration utility and the Ctrl-R Utility, respectively.
2.1.1.1 Creating Storage Configuration Using WebBIOS
The following procedure describes the creation of a RAID 1 array. You can use other RAID levels, and the steps are the
same except when selecting the RAID level. In a RAID 1 array, the RAID controller duplicates all data from one drive to
a second drive. The RAID 1 array provides complete data redundancy, but at the cost of doubling the required data
storage capacity. It is appropriate for small databases or any other environment that requires fault tolerance but
small capacity.
