A storage system has a resiliency scheme to enhance storage system performance. The storage system composes a RAID stripe. The storage system mixes an ordering of portions of the RAID stripe, based on reliability differences across zones of the solid-state memory. Each zone of the solid state memory corresponds to a type of solid state memory. The storage system writes the mixed ordering RAID stripe across the solid-state memory.

A memory system comprising a first storage region which stores first firmware corresponding to an external first electronic control apparatus; a second storage region which stores second firmware corresponding to an external gateway and third firmware corresponding to the first electronic control apparatus; and a controller configured to transmit the second firmware and the third firmware to the gateway on the basis of a first command received from the gateway, and transmit the first firmware to the gateway on the basis of a second command received from the gateway.

According to embodiments of the present disclosure, a method, device and computer program product for storage management are proposed. The method comprises: obtaining, in a first virtual storage device, a first portion storing a source file, the source file being used to update a target file; determining a second portion in the first virtual storage device, data stored in the second portion being changed relative to data stored in a second virtual storage device, the data stored in the second virtual storage device including the target file; determining a changed portion based on the first portion and the second portion, the changed portion indicating changed data of the source file relative to the target file; and updating the target file based on the changed portion. Therefore, the present solution can reduce data transmission and resource consumption.

A method and apparatus with a data storage device receives a data write request that is sent by a first tenant, and determines, from a plurality of resource zones (RZs) and based on the data write request and storage permission of the first tenant for each of the plurality of RZs. The data storage device further determines distribution of N duplicates in the at least one RZ based on the data write request and a first data distribution policy, and stores the N duplicates into at least one node corresponding to the at least one RZ based on distribution of the N duplicates in the at least one RZ and a second data distribution policy.

Systems and methods for recording information at a granular level; checking and verifying that data is used and processed is consistent with an entity’s internal policies and/or external regulations; and producing reports to authorized users (e.g., individuals and organizations) with information are provided. The system and methods capture required data in an immutable fashion so that users outside of an entity (e.g., public, third parties) can check and audit that internal policies and other regulatory policies and frameworks are followed.

A solid state drive having at least one component solid state drive, a spare solid state drive, and a drive aggregator. The drive aggregator has at least one host interface, at least one drive interface connected to the at least one component solid state drive, and an interface connected to the spare solid state drive. The drive aggregator is configured to maintain, in the spare solid state drive, a copy of a dataset that is stored in the component solid state drive. In response to a failure of the component solid state drive, the drive aggregator is configured to substitute a function of the component solid state drive with respect to the dataset with a corresponding function of the spare solid state drive, based on the copy of the dataset maintained in the spare solid state drive.

A memory system includes a storage device including a turbo write buffer and a user storage area implemented with a nonvolatile memory, and a host configured to transfer a read request to the storage device. In response to the read request, the storage device transfers read data and read data information including attributes of the read data to the host.

Reversing deletion of a virtual machine including managing, by a storage system, a repository of virtual machine snapshots on a datastore; receiving, by the storage system, a request to recover a deleted virtual machine from the datastore; accessing, by the storage system, the repository of virtual machine snapshots on the datastore to generate a list of deleted virtual machines associated with virtual machine snapshots in the repository of virtual machine snapshots; receiving, by the storage system, a selection of one of the deleted virtual machines in the list of deleted virtual machines; and recovering, by the storage system, the selected deleted virtual machine using a virtual machine snapshot for the selected deleted virtual machine.

A semiconductor storage device includes memory cells, select transistors, memory strings, first and second blocks, word lines, and select gate lines. In the memory string, the current paths of plural memory cells are connected in series. When data are written in a first block, after a select gate line connected to the gate of a select transistor of one of the memory strings in the first block is selected, the data are sequentially written in the memory cells in the memory string connected to the selected select gate line. When data are written in the second block, after a word line connected to the control gates of memory cells of different memory strings in the second block is selected, the data are sequentially written in the memory cells of the different memory strings in the second block which have their control gates connected to the selected word line.

A memory system comprising a first storage region which stores first firmware corresponding to an external first electronic control apparatus; a second storage region which stores second firmware corresponding to an external gateway and third firmware corresponding to the first electronic control apparatus; and a controller configured to transmit the second firmware and the third firmware to the gateway on the basis of a first command received from the gateway, and transmit the first firmware to the gateway on the basis of a second command received from the gateway.
