摘要: An aggregation module combines a plurality of logical address spaces to form a conglomerated address space. The logical address spaces comprising the conglomerated address space may correspond to different respective storage modules and/or storage devices. An atomic aggregation module coordinates atomic storage operations within the conglomerated address space, and which span multiple storage modules. The aggregation module may identify the storage modules used to implement the atomic storage request, assign a sequence indicator to the atomic storage request, and issue atomic storage requests (sub-requests) to the storage modules. The storage modules may be configured to store a completion tag comprising the sequence indicator upon completing the sub-requests issued thereto. The aggregation module may identify incomplete atomic storage requests based on the completion information stored on the storage modules.

摘要: A method for enforcing data integrity in an RDMA data storage system includes flushing data write requests to a data storage device before sending an acknowledgment that the data write requests have been executed. An RDMA data storage system includes a node configured to flush data write requests to a data storage device before sending an acknowledgment that a data write request has been executed.
