Systems and methods for a controller including controller memory and logic are presented herein. The logic is configured to control access to a persistent storage media and, in response to one or more commands, determine an intermediate parity value based on a first parity calculation by sending a uni-directional command to the persistent storage media. The logic is further configured to store, in the controller memory, the intermediate parity value, and determine a final parity value based on the intermediate parity value and a second parity calculation.

ON-SSD erasure coding with uni-directional commands

Systems, apparatuses and methods may provide for technology that detects, via a processor external to a solid state drive (SSD), internal information associated with the SSD, detects background operations with respect to the SSD based on the internal information, wherein the background operations include one or more of current operations or predicted operations, and adjusts a hierarchical data placement policy based on the background operations.

Disk caching and/or tiering with device internal busy information

Dynamically controlled interrupt coalescing is performed by enabling interrupt coalescing when the queue depth of the submission queue is high and disabling interrupt coalescing when the queue depth of the submission queue is low to maintain a required quality of service for a solid state drive. The minimum number of completions in the completion queue to trigger an interrupt is modified based on the queue depth of the submission queue. The minimum number of completions is increased when there is an increase in the queue depth of the submission queue and decreased when there is a decrease in the queue depth of the submission queue.

Method and apparatus to perform dynamically controlled interrupt coalescing for a solid state drive

A storage system includes a NAND storage media and a nonvolatile storage media as a write buffer for the NAND storage media. The write buffer is partitioned, where the partitions are to buffer write data based on a classification of a received write request. Write requests are placed in the write buffer partition with other write requests of the same classification. The partitions have a size at least equal to the size of an erase unit of the NAND storage media. The write buffer flushes a partition once it has an amount of write data equal to the size of the erase unit.

A computing node includes a NIC and processing circuitry configured to select a subset of computing resources from a set of available computing resources to initiate a parameter sweep associated with a parameter sweep request received. A plurality of settings is applied to each computing resource of the subset to generate a plurality of resource mappings during the parameter sweep. Each resource mapping of the plurality of resource mappings indicates at least one computing resource of the subset and a corresponding at least one setting of the plurality of settings. Telemetry information for the subset of computing resources is retrieved, the telemetry information is generated during the parameter sweep. A resource mapping of the plurality of resource mappings is selected based on a comparison of the telemetry information with an SLO. A reconfiguration of the available computing resources is performed based on the selected resource mapping.

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. The controller is further to issue commands to one or more EC storage drives to read the old data, compute result data as the old data XOR a galois field coefficient of the one or more EC storage drives multiplied by the intermediate data, and atomically write the old data to the intermediate buffer of the one or more EC storage drives and write the result data to the one or more EC storage drive's NVM. Other embodiments are disclosed and claimed.

Erasure coding write hole closure for solid-state drive (SSD) erasure coding

Systems and methods for a controller including controller memory and logic are presented herein. The logic is configured to control access to a persistent storage media and, in response to one or more commands, the logic determines an intermediate parity value based on a first parity calculation, and using the intermediate parity value determines a final parity value based on the intermediate parity value and a second parity calculation. Determining the intermediate parity value includes sending a uni-directional command to read an old data value from an address indicated in the uni-directional command, perform an exclusive-or operation on the old data value and a new data value indicated in the uni-directional command to determine the intermediate parity value and store, in the persistent storage media, the intermediate parity value at a location associated to an index indicated in the uni-directional command.

An embodiment of a semiconductor apparatus may include technology to selectively determine a set of data for background refresh based at least in part on host-provided information, and refresh the determined set of data on a persistent storage media as a background operation. Other embodiments are disclosed and claimed.

Techniques to facilitate an out-of-band (OOB) management in a virtualization environment include examples of assigning an endpoint identifier to a domain mapped to physical memory addresses of one or more storage devices coupled with a computing platform. The domain may enable software or a device driver executed by a virtual machine (VM) to access, manage or control at least a portion of the one or more storage devices. Examples also include receiving or forwarding messages through an OOB communication link coupled with the computing platform to a management entity to facilitate OOB management of the software or the device driver executed by the VM.

Techniques to facilitate out of band management in a virtualization environment

A system including a storage drive and a semiconductor apparatus coupled to the storage drive, is provided. The semiconductor apparatus may include one or more substrates and logic coupled to the one or more substrates, the logic coupled to the one or more substrates to: initiate managing resources of the storage drive and, if the storage drive loses capacity, determine an amount of capacity loss, create a reserved file that is associated with logical memory space in a file system, based on the amount of the capacity loss, and erase at least a portion of the reserved file so that logical memory space associated with an un-erased portion of the reserved file is usable by the storage drive.

Technology to manage capacity loss in storage drives

Technologies for end-to-end quality of service for I/O operations include a compute device in an I/O path. The compute device receives from another of the compute devices in the I/O path, an I/O request packet. The I/O request packet includes one or more QoS deadline metadata. The QoS deadline metadata is indicative of latency information relating to a currently executing workload relative to a specified QoS. The compute device evaluates the QoS deadline metadata and assigns a priority to the I/O request packet as a function of the evaluated metadata.
