Abstract: Fabric modules in a storage system offer differing device IDs from a deterministic sequence to a storage device being added to the storage system. The storage device that is being added accepts a device ID that is higher in the deterministic sequence. The fabric module that offered the device ID same as was accepted by the storage device determines to proceed with initializing the storage device.

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 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 method for migration of data is provided. The method includes triggering a rebuild of data according to a first migration mechanism from a first storage drive to a second storage drive. Monitoring space utilization associated with the second storage drive, and adaptively switching the migration of the data from the first migration mechanism to a second migration mechanism based on the monitoring.

Abstract: A method of using boot-time metadata in a storage system is provided. The method includes writing a fragmentation stride to a solid-state storage device of the storage system, the fragmentation stride defining a granularity on which fragmentation of erase blocks of the solid-state storage device occurs. The method includes allocating portions of erase blocks for at least one process in the storage system, in accordance with the fragmentation stride and writing boot up metadata at offsets that are based on the fragmentation stride, in the solid-state storage device.

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 determining that a size of a buffer of a storage system should be adjusted. The storage system comprises a non-volatile random-access memory (NVRAM), single level cell (SLC) flash memory, and quad level cell (QLC) flash memory. The buffer of the storage system comprises one or more of the NVRAM and a portion of the SLC flash memory. The method also includes adjusting the size of the buffer of the storage system to a first size.

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.

Abstract: A method for writing to a storage memory is provided. The method includes determining erase block size for each of a plurality of erase blocks of the storage memory, wherein at least two of the plurality of erase blocks have differing erase block sizes. The method includes forming a plurality of data segments and writing the plurality of data segments across the plurality of erase blocks of the storage memory, with at least one of the plurality of erase blocks storing portions of two or more of the plurality of data segments.
