Embodiments of the disclosure provide a computer-implemented method for data replication from a first storage to a second storage. In the method, data replication control blocks for data blocks stored in the first storage and needed to be transmitted may be generated. The data replication control blocks may be sorted in an ascending order of probabilities of expected overwrites of the respective data blocks. The data blocks may be transmitted from the first storage to the second storage according to the sorted data replication control blocks.

Data file storage systems and methods that bind a local portable data storage device to remote data storage space with an emergent data file storage system. Data files and directory nodes are associated with data aspect pairs, each comprised of a series of interdependent blocks of characteristically high-entropy data. Blocks of data comprising a remote data aspect are transferred to remote data aspect storage locations. A single block of data comprising a local data aspect is transferred separately to the local portable data storage device. Neither a local data aspect nor a remote data aspect contains information about the corresponding data file or directory node.

Disk based emulation of tape libraries is provided with features that allow easier management and administration of a backup system and also allow increased flexibility to both archive data on tape at a remote location and also have fast restore access to archived data files. Features include automatic emulation of physical libraries, and the retention and write protection of virtual tapes that correspond to exported physical tapes.

An example method of enriching a storage provider of a virtualized computing system with metadata managed by a container orchestrator executing in the virtualized computing system is described. The method includes detecting, by a metadata sync service executing as an extension of the container orchestrator, metadata that is included in a persistent volume-based (PV-based) object managed by the container orchestrator, the PV-based object referencing a persistent volume; and pushing, by the metadata sync service, the metadata to the storage provider to augment a storage volume object managed by the storage provider, the storage volume object referencing a storage volume backing the persistent volume.

The present application describes embodiments of an interface for coupling flash memory and dynamic random access memory (DRAM) in a processing system. Some embodiments include a dedicated interface between a flash memory and DRAM. The dedicated interface is to provide access to the flash memory in response to instructions received over a DRAM interface between the DRAM and a processing device. Some embodiments of a method include accessing a flash memory via a dedicated interface between the flash memory and a dynamic random access memory (DRAM) in response to an instruction received over a DRAM interface between the DRAM and a processing device.

Provided are a computer program product, system, and method for using mirror indicators to indicate whether to mirror tracks in a data set in a primary volume mirrored to a secondary volume. A table includes a mirror indicator for each of a plurality of tracks in at least one data set in the primary volume indicating whether a track is to be mirrored to the secondary volume. In response to a write command of write data for one of the tracks in the primary volume, creating a record set in a cache for the primary volume including write data for the track to transfer to the secondary volume in response to the mirror indicator for the track indicating that the track is to be mirrored. The write data in the record set is transferred from the cache to the secondary volume.

A processor of a storage controller stores a parameter according to a command that has been transferred from a front-end unit to a first area in a first memory area and issues notification to the front-end unit regarding an address of a second area in a second memory area which is mapped to the first area, the front-end unit generates a data packet whose destination is the notified address and stores the generated data packet at the address of the second memory area, and an interface unit reads the parameter stored in the first area in the first memory area which is mapped to the second area of the address based on the destination address stored in a header of the data packet which has been stored in the second memory area and executes processing of the system function according to the command.

Techniques expand storage space. Such techniques can create a storage stripe group during a shuffling operation after a storage device being added, without waiting for full completion of the shuffling operation. Such techniques can effectively reduce the waiting time for creating the storage stripe group. Besides, such techniques can support partial mapping of the storage stripe group, such that the storage resources mapped to the storage stripe group can be rapidly utilized.

Provided are an apparatus, system and method for offloading data transfer operations between source and destination storage devices to a hardware accelerator. The hardware accelerator includes a memory space and control logic to receive, from a host processor, a command descriptor indicating at least one source storage device having transfer data to transfer to at least one destination storage device and a computational task to perform on the transfer data. The control logic sends read commands to the at least one source storage device to read the transfer data to at least one read buffer in the memory space and performs the computational task on the transfer data to produce modified transfer data. The control logic writes the modified transfer data to at least one write buffer in the memory space to cause the modified transfer data to be written to the at least one destination storage device.

A command to transfer data in a portion of a memory component to a recovery portion of a different memory component is received from a host system, wherein the portion of the memory component is associated with a portion of the memory component that has failed, and the data in the portion of the memory component is recovered and transferred to the recovery portion of the different memory component without moving or processing the data through the host system responsive to receipt of the command.
