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.
