Intel® RAID Controller RS2BL080
What is the RAID controller drive and array hierarchy?

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:

  1. One or more physical drives are selected and associated as an array.
  2. 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.
  3. 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.
