Abstract: A storage system comprises a storage comprising a nonvolatile storage medium, and a storage control apparatus for inputting/outputting data to/from the storage. The storage control apparatus comprises a memory for storing management information, which is information used in inputting/outputting data to/from the storage, and a control part for controlling access to the storage. The control part stores the management information, which is stored in the memory, in the storage as a base image, and when the management information is updated subsequent to the base image being stored in the storage, creates a journal comprising information related to this update, and stores the journal in the storage as a journal group which is configured from multiple journals.

Abstract: Accesses to a number of data blocks stored in a distributed storage are observed. Following observation of the accesses, the stored data blocks are redistributed. In one aspect, redistribution of the data blocks includes determining the access patterns for one or more of the data blocks based on the observed accesses, and determining the storage sizes for the one or more data blocks. Thereafter, based on the determined access patterns and determined storage sizes, the one or more data blocks are sorted. Subsequently, the one or more data blocks are redistributed or rebalanced across a number of storage devices of the distributed storage based on the sorting. In one aspect, the one or more data blocks are redistributed according to either a uniform distribution scheme or a proportional distribution scheme.

Abstract: A system includes a collection of central processing units, where each central processing unit is connected to at least one other central processing unit and a root path into at least 10 Tera Bytes of solid state memory resources. Each central processing unit directly accesses solid state memory resources without swapping solid state memory contents into main memory.

Abstract: A memory storage device and a memory controller and an access method thereof are provided. The memory storage device includes a rewritable non-volatile memory chip having a plurality of physical blocks. The access method includes configuring a plurality of logical blocks to be mapped to a part of the physical blocks and dividing the logical blocks into at least a first partition and a second partition, wherein the first partition records an auto-execute file. The access method also includes determining whether a trigger signal is existent and sending a media ready message to a host system if the trigger signal is existent, so as to allow the host system to automatically run the auto-execute file and receive a first password. The access method further includes determining whether to provide the logical blocks in the second partition to the host system according to the first password received from the host system.

Abstract: Dynamically allocates a new target volume and a Flashcopy map (fcmap) for ingest upon one of a mount operation and a clone operation breaking a FlashCopy chain for creating a stable FlashCopy Map (fcmaps) for ingest while a Flashcopy backup is mounted.

Abstract: A method of operating a memory system includes; storing data in a buffer region of the nonvolatile memory, later issuing a migration request directed to the data stored in the buffer region and executing a migration operation to move the data from buffer region to a main region of the nonvolatile memory device. Upon completion of the migration operation, marking a migration operation completion time, and after an initial verify shift (IVS) time has elapsed following the migration operation completion time, updating a mapping table associated with the data in view of the executed migration operation.

Abstract: A method of managing a memory by an electronic device is provided. The method includes configuring a swap data amount per unit time, identifying an actual use amount of swap data, and comparing the identified actual use amount of the swap data with the configured swap data amount per unit time.

Abstract: Execution of a transaction mode setting instruction causes a computer processor to be in an atomic write-only mode ignoring conflicts to certain read-sets of a transaction during transactional execution. Write-set conflicts may still cause a transactional abort. Absent any aborting, the transaction's execution may complete, by committing transactional stores to memory and updating architecture states.

Abstract: A program execution device includes a program loader reading a machine language program including a machine language code and access frequency information; an address conversion table creator creating an address conversion table including entries, each of which indicates a relation between a logical address range and a physical address range; and a TLB register registering, in a TLB, an entry of the address conversion table storing a logical address range accessed according to the machine language code. When determining that the frequency of access to a logical address range is high based on the access frequency information, the address conversion table creator adjusts the size of an entry storing this logical address range to an appropriate size.

Abstract: The present disclosure relates generally to a method and system for creating, replicating, and providing access to virtual snapshots of a disk storage block of a disk storage system or subsystem. In one embodiment, the present disclosure relates to a virtual snapshot accessible to local users of a local data storage device. The virtual snapshot may direct local users to a snapshot stored on computer-readable storage medium at a remote data storage site, but give the appearance as if data of the corresponding snapshot is stored locally. The virtual snapshot is replaced by replication of the snapshot from the remote data storage site to the local data storage device. Each snapshot may relate to data of a logical data volume, the logical data volume being an abstraction of data blocks from one or more physical storage devices.
