Provided are a computer program product, system, and method for handling failure of a command to add a record to a log. The log has records at log addresses. Each record in the log includes a key and value and the log addresses map to physical addresses in the storage. A first command for a key and value pair for a record at a specified log address in the log to add to a selected log address in the log is sent. A second command for the key and value pair for the record at the specified log address with a resend parameter set is sent in response to not receiving the selected log address. In response to receiving the second command with the resend parameter set, the log is scanned to determine a log address having the key and value pair. The determined log address is returned.

An example method includes identifying, based on a request to write data to a volume provided by storage nodes in a storage node cluster, a cluster hierarchy associated with the storage node cluster, the cluster hierarchy identifying storage characteristics of the storage nodes, wherein the cluster hierarchy is based on data characterizing performance and storage capabilities of the storage nodes; based on the request, selecting a storage node for storing the data in the volume, the selecting being based, at least in part, on the storage characteristics identified by the cluster hierarchy and on one or more data distribution parameters associated with the storage volume; and transmitting the data to the storage node.

Apparatuses and methods related to mitigating unauthorized memory access are described. Mitigating unauthorized memory access can include verifying whether an access command is authorized to access a protected region of a memory array. The authorization can be verified utilizing a key and a memory address corresponding to the access command. If an access command is authorized to access a protected region, then a row of the memory array corresponding to the access command can be activated. If an access command is not authorized to access the protected region, then a row of the memory array corresponding to the access command may not be activated.

A nonvolatile memory device includes a memory cell array including a plurality of first segments having a write data, and a plurality of second segments having a programmed information defining a programmed segment from the plurality of first segments. A randomizer is configured to randomize the write data. An error correction circuit is configured to perform an error correction operation on the write data. A control logic is configured to determine the programmed information from an address received from a memory controller, and to determine whether to operate the randomizer and the error correction circuit based on the determination of the programmed information during the program operation. A page buffer is configured to store the write data and the programmed information during the randomizing and the error correction operation.

Method and system are provided for storage allocation enhancement of microservices. A method carried out at a microservice orchestrator, includes: categorizing a microservice container, wherein the categorization defines a predicted storage behavior of the microservice container input/output operations; and providing the categorization in association with the microservice container input/output operations to a storage system for use in storage allocation of the input/output operations. A method at a storage controller includes: receiving microservice container input/output operations with an associated categorization, wherein the categorization defines a predicted storage behavior of the microservice container input/output operations; and using the associated categorization for optimizing storage allocation for the input/output operations and/or optimizing garbage collection performance.

In a semiconductor device in which components to be a basic configuration unit are arranged in an array shape for calculating an interaction model, a technique capable of changing a topology between the components is provided. A semiconductor device includes a plurality of units each of which includes a first memory cell for storing a value indicating a state of one node of an interaction model, a second memory cell for storing an interaction coefficient indicating an interaction from a node connected to the one node, and a calculation circuit for determining a value indicating a next state of the one node based on a value indicating a state of the connected node and on the interaction coefficient. In addition, the semiconductor device includes a plurality of switches for connecting or disconnecting the plurality of units to/from each other.

A distributed storage system comprises a first module and a second module. The first module processes read requests for an address range, to send to the second module. The first module receives an address associated with a read request for a data page stored on the second module. A method searches a table on the first module for a content-based signature of the data page based on the address and provides the data page from a first module read cache if the content-based signature is in the read cache, where content-based signatures in the table are associated with the address range.

A storage management system monitors relationships between data sets stored on current implementation resources, such as a storage servers. The relationships may be used to determine whether a data set should be moved from a current implementation resource to an available implementation resource.

Examples described herein relate to management of containers in a storage system. Examples may receive a container specification corresponding to a container image. Examples may obtain the container image from a container repository and select storage volumes based on the container specification. Examples may execute one or more containers from the container image on a controller of the storage system within resource limits. Examples may dynamically select the controllers based on resource availability at the plurality of controllers. Examples may allow scheduling the execution of the containers at a specific controller at a predetermined time. The execution may include performing one or more batch operations on the storage volumes. Examples may further enable monitoring a status of the container and providing alerts in response to a detection of a failure event associated with the container.

Providing memory bandwidth compression using compression indicator (CI) hint directories in a central processing unit (CPU)-based system is disclosed. In this regard, a compressed memory controller provides a CI hint directory comprising a plurality of CI hint directory entries, each providing a plurality of CI hints. The compressed memory controller is configured to receive a memory read request comprising a physical address of a memory line, and initiate a memory read transaction comprising a requested read length value. The compressed memory controller is further configured to, in parallel with initiating the memory read transaction, determine whether the physical address corresponds to a CI hint directory entry in the CI hint directory. If so, the compressed memory controller reads a CI hint from the CI hint directory entry of the CI hint directory, and modifies the requested read length value of the memory read transaction based on the CI hint.
