Abstract: A command is transmitted to a storage device to relocate first data that partially fills a first erase block of the storage device and second data that partially fills a second erase block of the storage device to a third erase block of the storage device, wherein the command causes the relocation of the first data and the second data while bypassing sending the data to the storage controller. An acknowledgement that the first data and the second data have been stored at the third erase block is received from the storage device.

Abstract: A first amount of energy to be stored at one or more power loss protection (PLP) components is determined to enable storage of data at a plurality of storage devices of a storage system upon an occurrence of a power failure. A first voltage is provided to the one or more PLP components that corresponds to the first amount of energy. A second amount of energy to be stored at the one or more PLP components is determined based on a change in the storage system. A second voltage is provided to the one or more PLP components that corresponds to the second amount of energy.

Abstract: A storage system forms an allocation unit for writing into solid-state storage memory. The allocation unit is formed from at least a portion of a first erase block and a first sub block of a partitioned second erase block. The system forms multiple subsequent allocation units. Each subsequent allocation unit is formed from a remaining second sub block of a partitioned erase block and at least a portion of a next erase block. Forming the subsequent allocation units consumes each of multiple erase blocks in a cascading sequence. The system allocates the allocation unit and the subsequent allocation units for writing in the storage system.

Abstract: A storage system is provided. The storage system includes a plurality of non-volatile memory modules and a storage system controller. One or more non-volatile memory modules include a multiplane die. A processing device of the storage system controller is configured to determine that a number of planes of the multiplane die used simultaneously for accessing data should be changed. In response to determining that the number of planes the multiplane die used simultaneously for accessing data should be changed, the processing device is configured to move one or more portions from an existing erase block to a new erase block, the existing erase block being a different size than the new erase block.

Abstract: A storage system and related method are for operating solid-state storage memory in a storage system. Zones of solid-state storage memory are provided. Each zone includes a portion of the solid-state storage memory. The zone has a data write requirement for the zone for reliability of data reads. The storage system adjusts power loss protection for at least one zone. The adjusting is based on the data write requirement for the zone and responsive to detecting a power loss.
