Abstract: An update-insert (“upsert”) interface manages updates to key-value storage at a memory or storage device. An upsert token is used to store a key and data for a transform to update a previous value stored for a key-value pair. The upsert token processing includes an upsert command to generate the upsert token for an existing key-value pair and store the upsert token in one or more first non-volatile memory (NVM) devices maintained at a memory or storage device. A hash-to-physical (H2P) table or index stored in one or more second NVM devices of the memory or storage device is utilized to locate and read the data for the key and the data for the transform and coalesce the transform(s) into a current value for the key-value pair, thereby avoiding unnecessary read and write amplification when updating key-value storage.

Abstract: An apparatus comprises a controller comprising an interface comprising circuitry to communicate with a host computing device; and a relocation manager comprising circuitry, the relocation manager to provide, for the host computing device, an identification of a plurality of data blocks to be relocated within a non-volatile memory; and relocate at least a subset of the plurality of data blocks in accordance with a directive provided by the host computing device in response to the identification of the plurality of data blocks to be relocated.

Abstract: Techniques enable offloading operations to be performed closer to where the data is stored in systems with sharded and erasure-coded data, such as in data centers. In one example, a system includes a compute sled or compute node, which includes one or more processors. The system also includes a storage sled or storage node. The storage node includes one or more storage devices. The storage node stores at least one portion of data that is sharded and erasure-coded. Other portions of the data are stored on other storage nodes. The compute node sends a request to offload an operation to the storage node to access the sharded and erasure-coded data. The storage node then sends a request to offload the operation to one or more other storage nodes determined to store one or more codes of the data. The storage nodes perform the operation on the portions of locally stored data and provide the results to the next-level up node.

Abstract: An embodiment of an electronic storage system includes one or more storage drives, at least one or more of the storage drives supporting erasure coding (EC); and a controller including logic to control local access to the one or more storage drives. The controller, in response to a write command, is to for one or more storage drives, allocate an intermediate buffer in the storage drive's non-volatile memory (NVM) to store intermediate data. The controller is to issue commands to a first storage drive to read old data, compute the intermediate data of the first storage drive as XOR of the old data and new data received in the write command, and atomically write the intermediate data of the first storage drive to the intermediate buffer of the first storage drive and write the new data to the first storage drive's NVM. The controller is to read the intermediate data of the first storage drive from the intermediate buffer of the first storage drive.

Abstract: Power-fail safe compression and dynamic capacity for a storage device in a computer system is provided. Metadata stored with each logical block in non-volatile memory in the storage device ensures that the mapping table may be recovered and stored in volatile memory for use by the computer system after power is restored to the computer system. In addition, the metadata ensures that a list of free logical block addresses written to the storage device prior to shutting down the computer system to provide access to the additional capacity that is available in the storage device by storing compressed data in the storage device may also be recovered.

Abstract: Examples include techniques for managing high priority (HP) and low priority (LP) write transaction requests by a storage device. An embodiment includes receiving, at a storage controller for a storage device, a write transaction request from a requestor to write data to one or more memory devices in the storage device. When the write transaction request is for a high priority (HP) write, coalescing the write data into a transaction buffer in a memory of the storage device, sending an acknowledgment for the write transaction request to the requestor, and writing the write data into the one or more memory devices. When the write transaction request is for a low priority (LP) write, writing the write data into the one or more memory devices, and then sending an acknowledgment for the write transaction request to the requestor.

Abstract: To address the storage needs of applications that work with noisy data (e.g. image, sound, video data), where errors can be tolerated to a certain extent and performance is more critical than data fidelity, dynamic reliability levels enable storage devices capable of storing and retrieving data with varying degrees of data fidelity to dynamically change the degree of data fidelity in response to an application's request specifying reliability level. By allowing the application to specify the reliability level at which its data is stored and retrieved, dynamic reliability levels can increase read/write performance without sacrificing application accuracy. The application can specify reliability levels for different types or units of data, such as different reliability levels for metadata as opposed to data and so forth.

Abstract: An embodiment of a semiconductor apparatus may include technology to receive an application-related checkpoint request corresponding to a file of a file system stored on a persistent storage media, and determine one or more checkpoint operations internal to the persistent storage media to perform the application-related checkpoint request.

Abstract: Examples may include a storage appliance having a mass storage device and a compute engine communicating peer-to-peer with each other, with the compute engine including a programmable logic component to execute a function to read data from the at least one storage device, process the data; and write data to the at least one storage device.

Abstract: Examples herein relate to a storage system that separately handles portions of a write operation that are aligned and misaligned with respect to retrievable segments from a storage device. For misaligned portions, a buffer can be used to store misaligned retrievable segments and update the segments with content provided with the write operation. Aligned portions of content associated with a write request can be written directly to the storage medium or overwrite corresponding retrievable segments present in the buffer. A table or array can track logical block addresses that correspond to content in the buffer or in the storage. Content in the buffer can be kept in the buffer without being backed-up or persisted to the storage until a triggering event occurs such as power loss or low space in the buffer.

Abstract: Embodiments of the present disclosure may relate to a data storage controller that may include a host interface to receive a request from a host to perform a data copy operation on a non-volatile data storage component of a data storage device, where the request identifies one or more source ranges of the non-volatile data storage component from which data is to be copied, a destination range of the non-volatile data storage component to which the data is to be copied, and a transfer length in bytes for each of the one or more source ranges, and a processor coupled with the host interface to process the request from the host to perform the data copy operation to copy the data from the one or more source ranges to the destination range based at least in part on the transfer length in bytes. Other embodiments may be described and/or claimed.

Abstract: In one embodiment, a storage drive is configured to receive a selective flush command which causes the storage drive to selectively flush write data which has been identified in connection with the selective flush command, from volatile buffer memory to a nonvolatile storage memory. Conversely, write data stored in the volatile buffer memory which is not identified in connection with the selective flush command, may remain unaffected by the selective flush command, and thus may remain stored in the volatile buffer memory without being flushed to the nonvolatile storage memory as a result of the selective flush command. Other aspects are described herein.

Abstract: Provided are an apparatus, computer program product, system, and method for managing multiple regions of a non-volatile memory device. A first group of logical bands is assigned to a first memory region in which metadata will be stored and a second group of logical bands is assigned to a second memory region to which host data is written, wherein the second group of logical bands is larger than the first group of logical bands. Physical bands are mapped to the first number of logical bands and the second number of logical bands. Indication is returned to the host system of the first and second groups of logical bands assigned to the first and second memory regions, respectively. The host system directs requests for metadata to logical addresses in the first group of logical bands and directs request for file data to logical addresses in the second group of logical bands.

Abstract: A method and system to allow power fail-safe write-back or write-through caching of data in a persistent storage device into one or more cache lines of a caching device. No metadata associated with any of the cache lines is written atomically into the caching device when the data in the storage device is cached. As such, specialized cache hardware to allow atomic writing of metadata during the caching of data is not required.
