Abstract
A data processing system includes host data processors, a data storage system including data storage shared among the host data processors, and a data switch coupling the host data processors to the data storage system. The data storage system has host adapter ports coupled to the data switch. The data switch is programmed for distributing block I/O requests from the host data processors over the operable host adapter ports for load balancing of the block I/O requests among the operable host adapter ports. The shared data storage can be a file system striped across RAID sets of disk drives for load balancing upon disk director ports of the data storage system. The data processing system can be expanded by adding more data storage systems, switches for the additional data storage systems, and switches for routing block I/O requests from the host processors to the data storage systems.
