Devices and techniques are disclosed herein for more efficiently exchanging large amounts of data between a host and a storage system. In an example, a read command can optionally include a read-type indicator. The read-type indicator can allow for exchange of a large amount of data between the host and the storage system using a single read command.

An example non-transitory computer-readable storage medium comprising instructions that when executed cause a processor of a computing device to: in response to receiving a chunk size request from a recovery agent executable at an operating system of the computing device, determine a chunk size via firmware instructions of the computing device; transmit the chunk size from the firmware instructions to the recovery agent; receive data chunks of a recovery image from the recovery agent in sequence; store the data chunks in a storage device of the computing device; and construct the recovery image using the data chunks.

A method may include transferring data between a host and a first storage device through a first storage interface, transferring data between the host and a second storage device through a second storage interface, and transferring data between the first storage device and the second storage device through a peer-to-peer channel. A storage system may include a host interface, a first storage device having a first storage interface coupled to the host interface, a second storage device having a second storage interface coupled to the host interface, and a peer-to-peer bus coupled between the first and second storage devices. A storage device may include a storage medium, a storage device controller coupled to the storage medium, a storage interface coupled to the storage device controller, and a peer-to-peer interface coupled to the storage device controller.

Disclosed is a distributed storage system and methods for providing real-time localized data access from different storage nodes of the distributed storage system. Providing the localized data access may include tracking access frequencies with which a file is directly accessed from the different storage nodes, storing a source copy of the file at the first storage node in response to the access frequency at the first storage node being greater than the access frequency at the other storage nodes, caching the file at a second storage node, transferring control over the source copy from the first storage node to a third storage node based on a change to the access frequencies, and validating the cached copy of the file at the second storage node against the source copy at the third storage node prior to responding to a request for the file from the second storage node.

A system and method for effectively scheduling read and write operations among a plurality of solid-state storage devices. A computer system comprises client computers and data storage arrays coupled to one another via a network. A data storage array utilizes solid-state drives and Flash memory cells for data storage. A storage controller within a data storage array comprises an I/O scheduler. The storage controller is configured to receive a read request targeted to the data storage medium, and identify at least a first storage device of the plurality of storage devices which contains data targeted by the read request. In response to either detecting or predicting the first storage device will exhibit variable performance, the controller is configured to generate a reconstruct read request configured to obtain the data from one or more devices of the plurality of storage devices other than the first storage device.

A method for execution by a computing device of a storage network includes determining a utilization level of a local flash memory. The method further includes determining whether the utilization level compares favorably to a utilization threshold. When the utilization level compares favorably to the utilization threshold, The method further includes sending an encoded data slice storage solicitation message to another computing device. The method further includes receiving a plurality of encoded data slices from the other computing device, where data is dispersed storage error encoded into pluralities of sets of encoded data slices, and where the pluralities of sets of encoded data slices includes the plurality of encoded data slices. The method further includes storing the plurality of encoded data slices in the local flash memory.

Generating a transformed dataset for use by a machine learning model in an artificial intelligence infrastructure that includes one or more storage systems and one or more graphical processing unit (‘GPU’) servers, including: storing, within one or more storage systems, a transformed dataset generated by applying one or more transformations to a dataset that are identified based on one or more expected input formats of data received as input data by one or more machine learning models to be executed on one or more servers; and transmitting, from the one or more storage systems to the one or more servers without reapplying the one or more transformations on the dataset, the transformed dataset including data in the one or more expected formats of data to be received as input data by the one or more machine learning models.

A solid state drive having a drive aggregator configured to interface with a host system, and a plurality of component solid state drives connected to the drive aggregator. Each of the component solid state drives has a controller capable of processing commands from host systems. The drive aggregator is configured to receive commands from the host system and transmit commands to the component solid state drives to implement the commands received from the host system.

Provided is a storage system and a storage management method, aiming at reducing data movement amount necessary for using an expanded capacity in a distributed RAID. When only A (A is a positive integer) physical storage drives are added, a storage controller selects virtual parcels that are mapped to different physical storage drives among N physical storage drives and are included in different virtual chunks, changes an arrangement of the selected virtual parcels to the added A physical storage drives, and constitutes a new chunk based on unallocated virtual parcels selected from different physical storage drives among the (N+A) physical storage drives.

Techniques process and manage a storage unit access. In accordance with such a technique, a data access request which is from a host system and for a first storage unit in the first storage system is received, wherein the first storage unit is a secondary storage unit; and the data access request is forwarded to a second storage unit in a second storage system associated with the first storage unit via a redirection link from the first storage system to the second storage system, wherein the second storage unit is a primary storage unit. Through such techniques, the host system can be allowed to send a data access request for the secondary storage unit, so that the host system does not need to resend the data access request, thereby reducing delay and interruption caused by such requests.
