摘要： A storage system that includes one or more memory sections, one or more switches, and a management system. The memory sections include memory devices and a section controller that is capable of detecting faults with the memory section and transmitting messages to the management system regarding detected faults. The storage system includes a management system capable of receiving fault messages from the section controllers and removing from service the faulty memory sections. Additionally, the management system determines routing algorithms for the one or more switches. In another aspect, the switch may be capable of reading a data request including a data block identifier and routing the data request and any associated data through the switch on the basis of this data block identifier, such that a data request may be routed to a memory section. The section controller, in response, may determine the addresses in the memory devices storing the requested data, and transfers these addresses to those memory devices storing the requested data. Additionally, in yet another aspect, a data request for the data may be received over a communications path by the section controller. The section controller may determine the addresses in the memory devices storing the requested data, transfer these addresses to those memory devices storing the requested data, and transfer an identifier to the memory interface device. The memory device, in response, may read the data and transfer the data to its corresponding memory interface device. The memory interface device then may add to the data the identifier it received from the section controller and forward the requested bits towards their destination, such that the data need not pass through the section controller.
