A method for dynamic storage object configuration in a datacenter is provided. Embodiments include determining a number of fault domains in a storage cluster that have sufficient storage capacity for creating a storage object. Embodiments include applying a dynamic fault tolerance policy to the number of fault domains that have sufficient capacity for creating the storage object in order to determine a number of host failures to tolerate for the storage object, the dynamic fault tolerance policy specifying a manner of determining, for any respective storage object, a respective number of host failures to tolerate for storing the respective storage object in a respective storage cluster based on at least a respective number of fault domains of the respective storage cluster. Embodiments include implementing the storage object on the storage cluster based on the number of host failures to tolerate for the storage object.

A method for reordering data for storage includes detecting a data access pattern, associated with an application, for accessing a data, generating a remapping function based on a data access pattern information, the remapping function including operations to determine a reordering of the data based on address information for the data, receiving the data at a storage device, the data being ordered according to a first layout sequence, reordering the data, by the storage device, based on the remapping function, and storing the data, at the storage device, according to a second layout sequence corresponding to the data access pattern, the second layout sequence being different than the first layout sequence.

A system and method for property assignment in a data storage system is presented. A data storage system defines a client configuration profile comprising a set of storage operation properties, wherein the storage operation properties regulate criteria for performing storage operations by the data agent on client devices that are associated with the client configuration profile. A storage management system associates a first client device to the client configuration profile; and communicates the set of properties of the client configuration profile to property tables of corresponding objects in the first client device.

In a storage system including a plurality of nodes that provide a storage area and a drive that physically stores data, a parity group is configured with a plurality of data including user data stored in the storage area and redundant data for protecting the user data, a plurality of data in the parity group are stored in a storage area within one predetermined range across a plurality of nodes, and processing for dividing the predetermined range or processing for merging a plurality of predetermined ranges is performed based on a state of the predetermined range.

System and methods for using a discovery controller to establish network connections in a network that comprises Non-Volatile Memory Express™ over fabrics (NVMe-oF™) entities that support multicast change notifications comprise: in response to a change that affects at an NVMe-oF™ entity that has not yet established a connection with the discovery controller, generating a multicast change notification (MCN) that notifies the unconnected entity of the change and automatically communicating the MCN to the unconnected entity without requiring an explicit persistent connection to the discovery controller, e.g., to access storage ports in the network.

A storage system includes a nonvolatile memory, a controller that controls writing and reading of data to and from the nonvolatile memory, a first interface, and a second interface, and is connected to a host device via the first interface and the second interface. While the host device is being started, a boot loader read from the nonvolatile memory is transferred to the host device via the second interface, and the first interface is initialized in parallel. After the host device is started, write data and read data to or from the nonvolatile memory via any one or both of the first interface and the second interface.

A method includes: receiving control data at a first data selector of a plurality of data selectors, in which the control data comprises (i) a configuration registry address specifying a location in a configuration state registry and (ii) configuration data specifying a circuit configuration state of a circuit element of a computational circuit; transferring the control data, from the first data selector, to an entry in a trigger table registry; responsive to a first trigger event occurring, transferring the configuration data to the location in the configuration state registry specified by the configuration registry address; and updating a state of the circuit element based on the configuration data.

A processing-in-memory (PIM) device includes a first group of storage regions, a second group of storage regions, and a plurality of multiplication/accumulation (MAC) operators. The MAC operators are configured to communicate with the first and second groups of storage regions through a global data input/output (GIO) line. A first storage region corresponding to a storage region of the first group of storage regions, a second storage region corresponding to a storage region of the second group of storage regions, and a first MAC operator corresponding to a MAC operator of the plurality of MAC operators constitute a MAC unit. The first MAC operator is configured to receive first data and second data from the first and second storage regions, respectively, through the GIO line to perform a MAC arithmetic operation of the first and second data and to output a result of the MAC arithmetic operation.

Methods, systems, and devices for techniques to reduce write amplification are described. A memory device may receive a write command from a host device and may determine that a quantity of commands stored in a buffer for execution by a memory array satisfies a first threshold. In some examples, the memory device may identify whether a write amplification parameter associated with the memory array satisfies a second threshold. The memory device may write data associated with the write command to the memory array using a first mode to write the data or a second mode to write the data based on determining that the quantity of commands satisfies the first threshold and/or identifying whether the write amplification parameter satisfies the second threshold. In some examples, the memory device may adjust a value of the first threshold or the second threshold or both based on the write amplification parameter.

Examples implementations relate to configuration of computational drives. An example computational drive includes a housing to be inserted in a drive bay of a host device, and persistent storage. The computational drive may also include a processor to respond to an insertion of the housing into the drive bay of the host device by configuring the computational drive to operate as a new node of a distributed file system, and connecting the computational drive to the distributed file system as the new node.
