A method, computer program product, and computing system for receiving a plurality of data streams on an SSD cache memory system associated with a backend storage system and writing a first of the plurality of data streams to a first portion of the SSD cache memory system.

Cache management system and method

A storage system in one embodiment comprises a host processor, and a solid-state storage device coupled to the host processor and comprising a non-volatile memory and a storage controller. The host processor is configured to initiate an error scanning operation on a designated portion of the non-volatile memory by directing at least one read command to the storage controller. The read command is configured to indicate to the storage controller that data read from the non-volatile memory responsive to the read command is not to be returned to the host processor. For example, the read command may illustratively comprise a Scatter Gather List (SGL) bit bucket descriptor indicating that the data read from the non-volatile memory responsive to the read command is to be discarded rather than returned to the host processor. The storage controller records any detected errors in a media error log and notifies the host processor of such errors.

A first endpoint comprises a fabric attach point for attachment to a memory fabric, a first media controller, and a first non-volatile memory media. The memory fabric comprises a reliability zone comprising the first endpoint and at least a second endpoint. The first media controller is configured to receive, from at least one processor coupled to the first endpoint via the at least one fabric attach point, a memory fabric store command to store an object in the reliability zone. The first media controller is further configured to store the object in the first non-volatile memory media, to receive from the second endpoint a message indicating that the same object has been stored by the second endpoint, and to send to the at least one processor a single acknowledgement indicating that the at least one object has been stored in both the first and second endpoints of the reliability zone.

A storage system in one embodiment comprises a host processor, a volatile memory associated with the host processor, and a solid-state storage device comprising a non-volatile memory. The host processor is configured to detect a particular power condition, such as a power failure condition, and responsive to the detected power condition to direct the copying of data from the volatile memory associated with the host processor to the non-volatile memory of the solid-state storage device. In conjunction with directing the copying of data from the volatile memory associated with the host processor to the non-volatile memory of the solid-state storage device, the host processor further directs the solid-state storage device to enter an enhanced write bandwidth operating mode in which the solid-state storage device temporarily at least partially suspends at least one specified background process that would otherwise tend to restrict an achievable write bandwidth of the solid-state storage device.

A system, computer program product, and computer-executable method of managing a solid state drive (SSD) in a data storage system, the system, computer program product, and computer-executable method including initializing the SSD to enable the SSD to request memory for bad block replacement, querying the SSD to determine a size of memory on the SSD reserved for dynamic over provisioning, and allocating a portion of the size of memory for bad block replacement.

Solid state drive bad block management

A method, computer program product, and computing system for identifying a low-write-frequency portion of a solid-state storage device. If it is determined that the low-write-frequency portion is of sufficient size to function as over-provisioning space for the solid-state storage device, the low-write-frequency portion is utilized as over-provisioning space.

Wear-leveling system and method

A method, computer program product, and computing system for obtaining N data segments for storage within N data planes included within a flash-memory storage device. Each of the N data planes includes a plurality of data blocks. A superblock is defined, wherein the superblock includes a data block from each of the N data planes included within the flash-memory storage device. Data is; and simultaneously writing data to each data block included within the superblock.
