SYSTEM AND METHOD FOR ABSTRACTING SATA AND/OR SAS STORAGE MEDIA DEVICES VIA A FULL DUPLEX QUEUED COMMAND INTERFACE TO INCREASE PERFORMANCE, LOWER HOST OVERHEAD, AND SIMPLIFY SCALING STORAGE MEDIA DEVICES AND SYSTEMS

摘要

A simplified host accesses SATA and SAS storage media devices by abstracting the SATA and SAS protocols with one full duplex protocol that supports full command queuing to each storage media device, whether SATA or SAS, where the abstraction protocol is performance-centric and supports common high-level read and write access to a pool of storage media devices, each of which may have a SATA or SAS interface. The abstraction protocol is link-agnostic and may be carried via a multiplicity of direct attach or networked interfaces, including but not limited to PCIe, Ethernet (e.g., 1 GbE, 10 GbE, 40 GbE, or 100 GbE), Infiniband, ThunderBolt, Firewire, USB, and/or custom interfaces. The abstraction protocol also supports communicating with port expanders and port multipliers.

1. A routable packet-switched network supported by an abstraction protocol comprising:
at least one host; a master controller, the master controller comprising a master processing element, a master controller interface to communicate with the host, and at least one master controller control link interface; and at least one edge controller, the edge controller comprising an edge processing element, an edge controller control link interface to communicate with the master controller via the master controller control link interface, a port multiplier communicating with a plurality of first storage media devices, and a port expander communicating with a plurality of second storage media devices, wherein the master controller and the edge controller communicate via the abstraction protocol, the abstraction protocol comprising a full-duplex protocol supporting full command queuing for the first and second storage media devices.
