    摘要: Performing a tune-up procedure on a storage device including determining, during a boot process, that a first storage device is available for a tune-up procedure, wherein the tune-up procedure prepares the first storage device for use after being offline; reserving the first storage device to perform the tune-up procedure, wherein reserving the first storage device prevents another system from performing the tune-up procedure on the first storage device; and executing the tune-up procedure on the first storage device.

    摘要: Continuous value data redundancy, including: receiving, by a storage system, a dataset; determining, based on a data resiliency metric, an integer redundancy value for the dataset from among a plurality of redundancy values; and generating, based on the integer redundancy value for the dataset, data recovery information for the dataset, wherein the integer redundancy value for the dataset is different from at least one other integer redundancy value for another dataset stored within the storage system.

    摘要: A storage unit has one or more processing devices, a solid-state drive and an open blocks cache memory. The open blocks cache memory holds open blocks of data or metadata and holds closed blocks of data or metadata pending writing to the solid-state drive. Closed blocks of data or metadata are written to the solid-state drive and open blocks of data or metadata are written to the open blocks cache memory. Values for open blocks in the open blocks cache memory are tracked. The values are adjusted in a first direction when an open block is written to the open blocks cache memory, and the values are adjusted in a second direction when an open block in the open blocks cache memory is closed and written from the open blocks cache memory to the solid-state drive.

    摘要: A command to relocate data is transmitted by a storage controller. The command includes first address information associated with a first set of blocks storing the data at one or more storage devices using a first programming mode and second address information associated with a second set of blocks at the one or more storage devices to store the relocated data using a second programming mode. The command causes the relocation of the data from the first set of blocks to the second set of blocks while bypassing sending the data to the storage controller. An acknowledgement is received that the relocated data has been stored at the second number of blocks.
