US Patent 10452279 Architecture for flash storage server

A storage server comprises a plurality of solid state drives (SSDs), a plurality of input/output (I/O) controllers, a switch, and a management controller. A first SSD of the plurality of SSDs comprises a plurality of queue pairs. The management controller is to allocate a first subset of the plurality of queue pairs in the first SSD to a first I/O controller, wherein the first I/O controller is to use the first subset of the plurality of queue pairs to read from and write to the first SSD. The management controller is further to allocate a second subset of the plurality of queue pairs in the first SSD to a second I/O controller, wherein the second I/O controller is to use the second subset of the plurality of queue pairs to read from and write to the first SSD.
