Abstract
A storage system comprises a storage array comprising a plurality of solid state storage devices (SSDs), a first processor comprising a first root complex of the storage system, a plurality of controller devices, and a first switch to interconnect the plurality of SSDs, the first processor and the plurality of controller devices. A first controller device of the plurality of controller devices is to connect the storage system to one or more remote servers. The first controller device is further to receive a first request from a first server of the one or more remote servers and determine whether the first request is a data request or a control request. The first controller device is further to send a first message to a first SSD of the plurality of SSDs via the first switch, bypassing the first processor, responsive to a determination that the first request is a data request.
