Writing data to storage utilizing a diverged thread for asynchronous write operations is provided. On a first thread, an analysis engine analyzes and identifies changed information to write to storage and an I/O manager copies the writes into buffers and places the buffers into a queue, while on a second thread, a flushless transactional layer (FTL) drive executes the writes to storage. By allowing the analysis to continue and enqueue writes on a first thread while the writes are written to storage on a second thread, the CPU and I/O of the system are utilized in parallel. Accordingly, efficiency of the computing device is improved.

A storage device controller addresses consecutively-addressed portions of incoming data to consecutive data tracks on a storage medium and writes the consecutively-addressed portions to the consecutive data tracks in a non-consecutive track order. In one implementation, the storage device controller reads the data back from the consecutive data tracks in a consecutive address order in a single sequential read operation.

Systems and methods for data storage management technology that enables a guest module of a virtual machine to indicate an order in which a host module should write data from physical memory to a secondary storage. An example method may comprise: identifying, by a processing device executing a host module, a plurality of modifications to physical memory made by a plurality of direct access operations executed by a guest module of a virtual machine; determining, by the host module, an order of the plurality of modifications to physical memory; receiving, by the host module, a synchronization request from the guest module; and responsive to the synchronization request, copying, by the host module, data from the physical memory to a secondary storage in view of the order of the plurality of modifications.

A system includes a read/write module and a caching module. The read/write module is configured to access a first portion of a recording surface of a rotating storage device. Data is stored on the first portion of the recording surface of the rotating storage device at a first density. The caching module is configured to cache data on a second portion of the recording surface of the rotating storage device at a second density. The second portion of the recording surface of the rotating storage device is separate from the first portion of the recording surface of the rotating storage device. The second density is less than the first density.

A base station (BS) for sharing downlink (DL) demodulation reference signals (DMRSs) between the DL data and the DL control signals comprises a storage device for storing instructions and a processing circuit coupled to the storage device. The processing circuit is configured to execute the instructions stored in the storage device. The instructions comprise transmitting a DL control signal on a first layer in a first time-frequency resource to the communication device; transmitting a DL data, associated with the DL control signal on a second layer in the first time-frequency resource and on the first layer and the second layer in a second time-frequency resource, to the communication device; and transmitting a set of DMRSs for the DL control signal and the DL data to the communication device.

Various zone forwarding management techniques disclosed herein generally provide efficient methods of data caching, steering, mapping, and migration to reduce write amplification and command latency. In one implementation, a zone-forward storage medium management method includes receiving commands to write data sets to target LBAs included in a consecutive sequence of LBAs, selectively mapping the sequence of LBAs to a plurality of contiguous physical zones, and selectively writing the data sets to the physical zones. Various techniques may be used to migrate valid data of the plurality of physical zones to one physical zone.

A storage system for continuing I/O without affecting drive box addition to a host computer includes: a plurality of drive boxes for connecting to a computer device that transmits commands for data reads or writes; and a storage controller connected to the drive boxes. A first drive box provides a first storage region to the computer device. The storage controller manages correspondence between the first storage region and a physical storage region of the drives constituting the first storage region. The first drive box receives a command for the first storage region from the computer device and transfers the command to the storage controller. The storage controller generates a data transfer command including a data storage destination based on the address management table, and transfers the command to the first drive box. The first drive box then transfers the data transfer command to the second drive box.
