an interpretive script language that provides an abstraction layer between redundant array of independent disks 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 on which to perform exclusive or operations .
