The fundamental purpose of a RAID system is to present a usable data storage medium (virtual drive) with some level of redundancy to a host operating system. The Intel® RAID firmware is based on the concept of associating physical drives in arrays and then creating a virtual drive from that array that includes a functional RAID level. To create a virtual drive and present it to the host operating system, the RAID firmware typically follows these steps:
- One or more physical drives are selected and associated as an array.
- One or more arrays are associated and given a RAID level. This process creates a virtual drive and provides an option to initialize the virtual drive.
- The RAID firmware presents the virtual drive to the operating system.
The virtual drive can then be partitioned and allocated to one or more logical drives by the operating system.
