Abstract

See full text

An interpretive script language that provides an abstraction layer between redundant array of independent disks (RAID) algorithms and RAID hardware architecture. The interpretive script language provides greater flexibility and performance over conventional RAID processors. The interpretive script language may be used with any RAID hardware architecture, is not dependent on a specific RAID algorithm, and enables efficient communication to a RAID processor from any entity that desires RAID services. The entity requesting RAID services sends a command to a RAID processor, which includes pointers to a script entry point for scripts stored in a table memory in the RAID processor, and pointers to the data and parity (for example, in a buffer memory) on which to perform exclusive OR (XOR) operations.
