Abstract
Example multi-device storage systems and methods provide disaggregated read/write operations. Read and/or write data requests are received from a host system at a storage controller for a plurality of storage devices. A target service host storage device is identified that hosts a target portion of a logical map of storage locations distributed among the plurality of storage devices. The target service host storage device identifies a destination storage device corresponding to a target location for the request. A data transfer from the host system to the destination storage device is processed for the request and the logical map of the target service host device is updated. The target service host storage device and the destination storage device may be different storage devices among the plurality of storage devices.
