The RAID software stack is composed of two major component groupings: the RAID firmware
embedded in the Flash memory and a set of host resident drivers and utilities installed on the host
system. All host-based software contains an OS dependent portion and an OS independent portion.
This allows for a consistent 'look and feel' across operating system platforms. A simple, custom
messaging protocol is used to communicate between the host driver or utility and the embedded
RAID firmware. The firmware is independent of the OS, I/O processor, and I/O bus through the
use of abstraction layers. This layered RAID software executes on a custom, multi-tasking, real-
time software executive and relies on the reuse of internal software communication 'building
blocks' to incorporate new technology and provide for new products.
