Abstract
Example storage systems and methods provide multichannel communication among subsystems, including a compute complex. A plurality of storage devices, a host, and a compute complex are interconnected over an interconnect fabric. The storage system is configured with a host-storage channel for communication between the host and the plurality of storage devices, host-compute channel for communication between the host and the compute complex, and a compute-storage channel for communication between the compute complex and the storage devices.
Claims20
A storage system, comprising:
- a compute subsystem comprising:
- a subsystem processor;
- a subsystem operating memory;
- and
- a host offload services module configured to use the subsystem processor and the subsystem operating memory to execute a host offload task received over a network interface from a host system, wherein the host offload task includes data-centric processing in addition to storage controller functions for a plurality of storage devices;
- and
- an interconnect fabric interconnecting the plurality of storage devices, the network interface, and the compute subsystem, wherein the interconnect fabric comprises:
- a network communication module configured for communication through the network interface to the host system;
- and
- a device interconnect module configured for communication with at least the plurality of storage devices;
- and
- a channel configuration comprising:
