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 controller includes a pre-boot configuration utility (WebBIOS) 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. Using an existing Windows device, 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
These steps 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 utility (WebBIOS) that creates the
virtual disk for the Windows OS is accessible during the power-on self-test (POST) part of bootup.
Refer to the MegaRAID SAS Software User Guide for more information about the WebBIOS configuration utility (CU).
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 RAID 1, the RAID controller duplicates all data from one drive to a
second drive. RAID 1 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.
Follow these steps to create the virtual disk in WebBIOS:
1. When the host computer is booting, hold down the Ctrl key and press the H key when the following text appears
on the window:

Press for WebBIOS
The Controller Selection window appears.
2. If the system has multiple SAS/SATA controllers, select a controller.
3. Click Start.
The main WebBIOS CU window appears.
