A software RAID/management communication system includes a chassis housing a software Redundant Array of Independent Disk (RAID) subsystem and a management subsystem that are each coupled to a storage device having a storage device memory subsystem. The software RAID subsystem provides a software RAID information request in the storage device memory subsystem that requests the management subsystem provide software RAID information associated with the operation of a software RAID provided by the software RAID subsystem, the software RAID subsystem then periodically accesses the storage device memory subsystem and, when the software RAID subsystem determines that the management subsystem has provided a software RAID information response in the storage device memory subsystem, the software RAID subsystem retrieves the software RAID information that was provided in the storage device memory subsystem by the management subsystem.

Software raid/management communication system

A software RAID/management communication system includes a chassis housing a software RAID subsystem coupled to a shared memory subsystem and storage devices, and a management subsystem that is coupled to the storage devices, and that is coupled to the shared memory subsystem via an MMBI connection. The management subsystem determines that at least one of the storage devices does not include a storage device memory subsystem that is configured for software RAID/management communications and, in response, transmits MCTP communications via the MMBI connection to retrieve RAID configuration information from the storage device(s) via the software RAID subsystem and the shared memory subsystem. The management subsystem then uses the RAID configuration information to perform at least one RAID management operation on at least one RAID logical storage device provided by the storage device(s).

A resilient software Redundant Array of Independent Disk (RAID)/management communication system includes a chassis housing a software RAID subsystem coupled to a plurality of storage devices that are also coupled to a management subsystem. The software RAID subsystem designates a first storage device in the plurality of storage devices as a primary storage device and a second storage device in the plurality of storage devices as a secondary storage device, and uses the respective storage device memory subsystem in the first storage device to transmit first management communications with the management subsystem. If the software RAID subsystem determines that the first storage device is unavailable, it uses the respective storage device memory subsystem in the second storage device to transmit second management communications with the management subsystem.

Resilient software raid/management communication system

A software Redundant Array of Independent Disk (RAID)/management trusted storage-device-based communication system includes a chassis housing a software Redundant Array of Independent Disk (RAID) subsystem, a storage device that is coupled to the software RAID subsystem and that includes a storage device memory subsystem, and a management subsystem that is coupled to the storage device. The management subsystem authenticates the storage device to establish management subsystem/storage device trust between the management subsystem and the storage device and, in response, uses the storage device to establish management subsystem/software RAID subsystem trust between the management subsystem and the software RAID subsystem. In response to establishing the management subsystem/storage device trust and the management subsystem/software RAID subsystem trust, the management subsystem transmits communications with the software RAID subsystem via the storage device memory subsystem in the storage device.
