<p>Disclosed is a storage system architecture. Array controllers are configured with at least 2M ports, where M is an integers greater than two that corresponds to the number of SAS domains or JBOD units in the system. Serial attached SCSI (SAS) domains or JBOD units are configured with at least 2N ports, where N corresponds to the number of array controllers in the system. At least two of each of the 2N ports are directly connected to a corresponding at least two of each of the 2M ports of each of the N array controllers, thereby establishing direct redundant connectivity between each of the N array controllers and each of the M SAS domains or JBOD units.</p> |
