摘要： Techniques are provided for provisioning zoned storage devices to sequential workloads. One method comprises obtaining a sequentiality classification of at least one workload of an application associated with a storage system comprising a plurality of zoned storage devices; and provisioning at least one of the zoned storage devices for storing the data of the at least one workload in response to the at least one workload being classified as a sequential workload. A sequentiality classification of a workload (e.g., as a sequential workload or a random workload) can be determined by: (i) evaluating the application name and/or application type of an application, (ii) learning input-output workload patterns, such as sequential read/write operations or random read/write operations, and/or (iii) detecting the application access mode to persistent volumes, such as a sequential write access mode.

摘要： A method of operating a memory controller is provided. The method includes: receiving a write request from a host; determining whether to inactivate a throttling operation based on whether the write request corresponds to a throttling disable word line and whether a memory block corresponding to the write request needs to be erased; and performing a write operation corresponding to the write request based on the determining.

摘要： A memory module according to some embodiments is operable in a computer system including a memory controller coupled to a memory channel. The memory module comprises a volatile memory subsystem, non-volatile (NV) memory subsystem and a module controller coupled to the volatile memory subsystem and the NV memory subsystem. The volatile memory subsystem includes dynamic random access memory (DRAM) devices and is configurable to communicate with the memory controller via the memory channel during memory read or write operations. The module controller is configured to output data strobe signals to accompany data from the volatile memory subsystem during a memory read operation and to output to accompany data strobes output by data buffers in response to data strobe signals from the memory controller during a system-initiated operation to transfer data from the NV memory subsystem to the volatile memory subsystem.

摘要： Embodiments are directed to tiered data store with persistent layers. A write tier in the file system for storing in a file system. A value for a performance metric that corresponds to write requests to the file system may be predicted based on characteristics of the write requests such that the performance metric may be determined based on a plurality of interactions with the write tier. The predicted value that exceeds a threshold value of the performance metric may be employed to cause performance of further actions, including: queuing a portion of the write requests in a memory buffer based on the predicted value and the threshold value; combining the queued portion of the write requests into s; storing the data segments in the write tier such that a measured value of the performance metric may be less than the threshold value.

摘要： In some implementations, a device may obtain a command table associated with a memory device, wherein the command table includes one or more entries associated with one or more respective commands, and wherein each entry, from the one or more entries, includes one or more units of data. The device may receive an indication of a modification associated with a first command, wherein the first command indicates a sequence of a first one or more units of data. The device may modify the command table based on the modification associated with the first command, wherein modifying the command table includes at least one of: adding an entry, that indicates the sequence, to the one or more entries to indicate the first command, or removing the entry from the one or more entries. The device may provide, to a controller of the memory device, an indication of the command table.

摘要： A controller of a storage device receives a stream of data from a host system. The stream of data corresponds to logical block addresses. The controller writes the stream of data to data block(s) in a device memory, each data block including respective super word line(s), each super word line including respective word line(s), and each word line corresponding to at least one logical block address. The controller generates a table for storing the logical block addresses in the order of data arrival. In response to receiving an update to one or more logical block addresses of the data block(s), the controller defragments at least one data block, based on the one or more logical block addresses, and writes data for one or more super word lines of the at least one data block to a new data block, based on the table, to retain the order.
