Abstract
A data storage system for transferring data between a host computer/server and a bank of disk drives through a system interface. The interface includes: a global memory; a plurality of front-end directors coupled between the global memory and the host computer/server; and, a plurality of back-end directors coupled between the global memory and the bank of disk drives. Each one of the first directors and each one of the second directors has a data pipe. Each one of such front-end directors passes front-end data between the global memory and the host computer through the data pipe therein and each one of the second directors passing back-end data between the global memory and the bank of disk drives through the data pipe therein. Each one of the first and second directors includes a data pipe controller, responsive to data fed to the data pipe, for performing a selected one of a plurality of functions on the data passing through the data pipe to obtain data from the global memory or to read such data into the global memory. The function is determined by descriptors associated with the data fed to the data pipe therein. A plurality of different, independently operable state machines i…
