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, realtime software executive and relies on the reuse of internal software communication 'building blocks' to incorporate new technology and provide for new products. 14 Technical Product Specification
