  • Patent number: 12079494
    Abstract: A storage system has a first storage and a second storage. The first storage has a first plurality of blades with first computing resources, first RAM resources and first solid-state storage resources.

  • Patent number: 12001684
    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.

  • Publication number: 20240170058
    Abstract: A method for page writes for triple or higher level cell flash memory is provided. The method includes receiving data in a storage system, from a client that is agnostic of page write requirements for triple or higher level cell flash memory, wherein the page write requirements specify an amount of data and a sequence of writing data for a set of pages to assure read data coherency for the set of pages. The method includes accumulating the received data, in random-access memory (RAM) in the storage system to satisfy the page write requirements for the triple or higher level cell flash memory in the storage system. The method includes writing at least a portion of the accumulated data in accordance with the page write requirements, from the RAM to the triple level cell, or the higher level cell, flash memory in the storage system as an atomic write.

  • Publication number: 20240012752
    Abstract: A system with storage memory and a processing device has a logical deletion to physical erasure time bound. The system dereferences data, responsive to a direction to delete the data. The system monitors physical blocks in storage memory for live data and the dereferenced data. The system cooperates garbage collection with monitoring the physical blocks, so that at least a physical block having the dereferenced data is garbage collected and erased within a logical deletion to physical erasure time bound.

  • Patent number: 11847013
    Abstract: Data associated with a write request is stored at a storage device of multiple solid-state storage devices. A determination as to whether the data stored at the storage device is readable is made by determining whether a number of subsequent programming operations have been performed since the data was stored at the storage device. A notification that the stored data is readable from the storage device is generated upon determining that the data is readable.

  • Patent number: 11846968
    Abstract: 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.

  • Publication number: 20230393742
    Abstract: A read request with a high priority indication is received. A determination as to whether an in progress flash programming operation would delay processing the read request for a threshold amount of time is made. In response to determining that the in progress flash programming operation delays processing the read request for the threshold amount of time, the in progress flash programming operation is interrupted.
