Abstract: A storage system has NVRAM (nonvolatile random-access memory), storage memory that includes SLC (single level cell) flash memory and QLC (quad level cell) flash memory, and a processor. The processor performs a method that includes selecting one of a plurality of write paths for incoming data, and writing the incoming data via the selected write path. A first write path includes writing to NVRAM, writing from NVRAM to SLC flash memory and writing from SLC flash memory to QLC flash memory. A second write path includes writing to NVRAM and writing from NVRAM to QLC flash memory, bypassing SLC flash memory. A third write path includes writing to SLC flash memory, bypassing NVRAM, and writing from SLC flash memory to QLC flash memory.

Abstract: A first set of physical units of a storage device of a storage system is selected for performance of low latency access operations, wherein other access operations are performed by remaining physical units of the storage device. A determination as to whether a triggering event has occurred that causes a selection of a new set of physical units of the storage device for the performance of low latency access operations is made. A second set of physical units of the storage device is selected for the performance of low latency access operations upon determining that the triggering event has occurred.

Abstract: A storage system is provided. The storage system includes a primary storage node comprising a primary processing device and a first set of non-volatile memory modules. The storage system also includes a secondary storage node comprising a secondary processing device a second set of non-volatile memory modules, the second storage node communicatively coupled to the primary storage node, the secondary storage node performs storage operations based on instructions received from the primary storage node. The primary processing device is to receive a request to access one or more of the first set of non-volatile memory modules and the second set of non-volatile memory modules and transmit instructions to perform a set of storage operations to the secondary storage node based on the request.

Abstract: A redundant array of independent drives (RAID) stripe is formed across a set of storage controllers of a plurality of storage controllers, wherein the RAID stripe comprises two or more of a plurality of modular storage devices of at least one of the set of storage controllers. The RAID stripe is written across the set of storage controllers.

Abstract: Data is received by one or more offload components that is to be stored in a storage system. The one or more offload components are operatively coupled to storage devices of the storage system via a first set of communication paths. The data is identified by a storage system controller operatively coupled to the storage devices via a second set of communication paths that are different than the first set of communication paths. An indication of a location in one or more of the storage devices for storing the data is transmitted to the one or more offload components. The indication causes the one or more offload components to store the data in the location of the one or more of the storage devices via the first set of communication paths.

Abstract: A storage system establishes a staging region, for temporary writing of arriving data, and a stable region, for transfer of data from the staging region, in storage memory. The storage system establishes resiliency groups, each with a characteristic level of redundancy that is settable on an individual basis. The storage system performs data accesses of data stripes in accordance with the staging region, the stable region, a first resiliency group and a second resiliency group.

Abstract: One or more performance parameters associated with data stored at a storage device of a plurality of storage devices are received by a storage controller. A first number of blocks of the storage device to a high resiliency portion and a second number of blocks of the storage device to a low resiliency portion of the storage device are allocated based on the one or more performance parameters.

Abstract: A storage system has a first memory, and a second memory that includes storage memory. The storage system has a processing device. The processing device is to select whether to write data to the first memory and write the data from the first memory to the second memory, or to write the data to the second memory bypassing the first memory. The processing device is to write portions of data for storage according to such selection.
