Abstract

The invention discloses an N-way directly connected any to any controller architecture and 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.

Description

Background technique [0001] Mass storage systems continue to provide ever-increasing storage capacity to meet user demands. Photo and movie storage and photo and movie sharing are examples of applications driving the growing demand for larger and larger storage systems. [0002] One solution to these growing demands is to use multi-inexpensive disk arrays. These arrays can be configured in such a way as to provide redundancy and error recovery without any loss of data. These arrays can also be configured to improve read and write performance by allowing simultaneous reading or writing of data to multiple disk drives. These arrays can also be configured to allow "hot plugging," which allows a failed disk to be replaced without interrupting the array's storage services. Whether or not any redundancy is provided, these arrays are often referred to as Redundant Arrays of Independent Disks (or more commonly referred to by the acronym RAID). People such as David A.Patterson from...
