A storage system and method for multiprotocol handling are provided. In one embodiment, a computing device is provided comprising a plurality of communication channels configured to communicate with a storage system, wherein a first communication channel has a faster data transfer speed than a second communication channel. The computing device also comprises a processor configured to determine a priority level of a command; send the command with an indication of its priority level to the storage system; in response to the command being a high-priority command, use the first communication channel for transferring data for the command; and in response to the command being a low-priority command, use the second communication channel for transferring data for the command. Other embodiments are provided.

A method for resolving an erred input/output (IO) flow, the method may include (i) sending over a path a remote direct write request associated with a certain address range; wherein the path is formed between a compute node of a storage system to a storage drive of the storage system; (ii) receiving by the compute node an error message related to the remote direct write request; wherein the error message does not indicate whether an execution of the remote direct write request failed or is only temporarily delayed; (iii) responding by the compute node to the error message by (a) preventing from sending one or more IO requests through the path, (b) preventing from sending at least one IO requests aimed to the certain address range; and (c) requesting, using a management communication link, to force an execution of pending IO requests that are related to the path; and (iv) reuse the path, by the compute node, following an indication that there are no pending IO requests that are related to the path.

A MON service migration method, apparatus, and device, and a readable storage medium, for use in any node in a distributed storage system. The method comprises: acquiring historical data of a MON service in a current node; in the node, determining a target magnetic disk for migrating the MON service, and migrating the historical data to the target magnetic disk; creating mount information of the MON service in a configuration file of the distributed storage system; and restarting the MON service according to the configuration file, such that the MON service migrates to the target magnetic disk. The present method does not need to remove nodes in the distributed storage system, and therefore the MON service migration process will not affect front-end services, improving the service capabilities and reliability of the distributed storage system.

Methods and apparatuses for transferring data from non-volatile memory to process accelerator memory are disclosed. In one embodiment, a process accelerator issues a transfer request for a resource at a host file system. The process accelerator receives, responsive to the transfer request, data from the host file system, wherein the data corresponds to the resource and the process accelerator receives the data directly from the host file system bypassing staging memory of the host. The process accelerator manipulates the data to obtain the resource. Thus, the process accelerator may obtain the resource directly from the host file system to minimize the number of transfers of the data.

Boot code is loaded to the data storage device controller in a flexible manner by being able to receive chunks of the boot code from two separate locations, the host memory buffer (HMB) and the memory device, which may be a NAND device. Part of the boot code may be received from the HMB and another part of the boot code may be received from the memory device. If either the HMB or the memory device can deliver the chunks faster than the other, then the controller can receive the chunks from the faster location and periodically confirm the speed of delivery to ensure the boot code latency is optimized. The controller is configured to track an HMB turnaround latency and derive whether a next request should be sent to the HMB or the memory device when the data is present in both the HMB and the memory device.

The disclosed technology includes a storage system with a docking station configured to serve as an interface between a host computer and a portable data pack including multiple storage drives. The docking station includes a drive-side connection interface that provides a physical and electrical coupling to each of the multiple storage drives in the portable data pack, a RAID controller, and mode selection logic for directing communications in route between the host computer and a select drive of the multiple storage drives along one of two selectable paths within the docking station, the first path permitting the host computer to interact with the select drive through the RAID controller and the second path permitting the host computer to interact with the select drive along a data channel that bypasses the RAID controller.

A storage controller for a storage area network that implements input-output commands in hardware is provided. Specific input-output commands are defined, including: a READ command, a WRITE command, a COPY command and a WRITE MIRROR command, all of which are implemented in hardware. A virtual logical unit table can be provided that enables the storage controller to implement a virtual storage management overlay function on top of a raw physical storage function.

An apparatus comprises at least one processing device. The at least one processing device is configured, for each of a plurality of logical storage devices of a storage system, to determine in a multi-path layer of a layered software stack of a host device a performance level for that logical storage device, to communicate the performance levels for respective ones of the logical storage devices from the multi-path layer of the layered software stack of the host device to at least one additional layer of the software stack above the multi-path layer, and to select particular ones of the logical storage devices for assignment to particular storage roles in the additional layer based at least in part on the communicated performance levels. The additional layer in some embodiments comprises an application layer configured to automatically select a particular one of the logical storage devices for a particular storage role.

The disclosure provides a system, computer readable medium, and computer-implemented method for managing data access. The method includes obtaining a data access request from a requestor for client data redundantly stored in at least two storage providers that are unknown to the requestor; identifying a service level objective for servicing the data access request; ranking the at least two storage providers based on the service level objective to identify one of the at least two storage providers to service the data access request; and providing the requestor with access to a copy of the client data using the one of the at least two storage providers.

Methods for improving resource connectivity for users' various computing devices are disclosed. An example method may include establishing a local connection with a sending device, receiving device status information and task status information from the sending device using the local connection, the task status information identifying at least one media content, and generating a user interface that includes a graphical representation of the device status information and a first control that, when selected, executes the at least one media content in an application on the receiving device. Another example method may include detecting an interaction with a UI element that sets a network sharing status to an on state, identifying a locally stored network as shareable, generating an instance of a network data type for the locally stored network, and associating the instance with the user account so that the locally stored network is shared with the user's other devices.
