Abstract: Systems and associated methods for flexible scalability of storage systems. In one aspect, a storage controller may include an interface to a fabric adapted to permit each storage controller coupled to the fabric to directly access memory mapped components of all other storage controllers coupled to the fabric. The CPU and other master device circuits within a storage controller may directly address memory an I/O devices directly coupled thereto within the same storage controller and may use RDMA features to directly address memory an I/O devices of other storage controllers through the fabric interface.
