According to one embodiment, a controller of a memory system reorders a plurality of first write commands in an order in which writing within a first zone is executed sequentially from a next write location within the first zone. The controller transfers a plurality of write data associated with the plurality of first write commands reordered from a write buffer of a host to an internal buffer in a same order as the order of the plurality of first write commands reordered, and writes the plurality of write data transferred to the internal buffer to a first storage region managed as the first zone.

Deduplicated storage disk space utilization

A plurality of different views of data associated with a storage domain stored on a deduplicated storage are traversed to determine data chunks belonging to each view of the plurality of different views of data associated with the storage domain. A request for a metric associated with disk space utilization of a group of one or more selected views of data included in the plurality of different views of data associated with the storage domain that are stored on the deduplicated storage is received. Data chunks belonging to the one or more selected views of data associated with the storage domain of the group but not other views of the plurality of different views of data associated with the storage domain that are stored on the deduplicated storage are identified. An incremental disk space utilization of the group is determined, including by determining a total size of the identified data chunks. The metric associated with disk space utilization is provided based on the determined incremental disk space utilization of the group.

REDUCING LATENCY OF HARDWARE TRUSTED EXECUTION ENVIRONMENTS

Example methods and systems are directed to reducing latency in providing trusted execution environments (TEEs). Initializing a TEE includes multiple steps before the TEE starts executing. Besides workload-specific initialization, workload-independent initialization is performed, such as adding memory to the TEE. In function-as-a-service (FaaS) environments, a large portion of the TEE is workload-independent, and thus can be performed prior to receiving the workload. Certain steps performed during TEE initialization are identical for certain classes of workloads. Thus, the common parts of the TEE initialization sequence may be performed before the TEE is requested. When a TEE is requested for a workload in the class and the parts to specialize the TEE for its particular purpose are known, the final steps to initialize the TEE are performed.

Intelligent management of stub files in hierarchical storage

Intelligent management of stub files in hierarchical storage is provided by: in response to identifying a file to migrate from a file system to offline storage, providing metadata for the file to a machine learning engine; receiving a stub profile for the file from the machine learning engine that indicates an offset from a beginning of the file and a length from the offset for previewing the file; and migrating the portion of the file from the file system to an offline storage based on the stub profile. In some embodiments this further comprises: monitoring file system operations; in response to detecting a read operation of the portion of the file: determining a file type; providing file data to the machine learning engine; and performing a supervised learning operation based on the file type and the file data to update the machine learning engine.

Charge loss scan operation management in memory devices

A memory system includes a memory device and a processing device, operatively coupled to the memory device. The processing device performs operations comprising: identifying an operating temperature of the memory device; determining that the operating temperature satisfies a temperature condition; modifying a scan frequency parameter for performing a scan operation on representative blocks of a set of blocks in the memory device; and performing the scan operation at a frequency identified by the scan frequency parameter.

Method for reassembling local disk managers and array groups

A method of reassembling a local disk manager (LDM) and array group (AGRP) includes starting a physical extent manager (PEM) configured to run on a number of nodes. The PEM on each node is configured to manage an AGRP running on the same node. A number of LDMs are reassembled, and each LDM is configured to manage virtual disks on each of the nodes. Once enough LDMs are reassembled, an AGRP can be reassembled.
