A method and system for rebuilding a Redundant Array of Independent Disks ('RAID'), the system comprising a RAID engine comprising one or more processing devices that facilitate packet communications with a plurality of storage devices, the packet communications including Read/Write-Rebuild opcodes and settings that prioritize read and write requests associated with a RAID rebuild of the plurality of storage devices, the Read/Write-Rebuild opcodes including rebuild input/output ('IO') read requests that read good portions of data and parity information from a set of the plurality of storage devices, and rebuild IO write requests that write data to a new one of the plurality storage devices wherein the written data includes data that is reconstructed by the RAID engine based on the data and the parity information.

Protocol for improving rebuild times of redundant array of independent disks

Methods, systems, and computer programs encoded on computer storage medium, for determining a unique identifier and a firmware version of each device; updating a cache storage to store the unique identifier and the firmware version for each device; generating, for a particular device, a command that is to be performed at the particular device; accessing the cache storage to identify the cached unique identifier and the cached firmware version for the particular device; transmitting, to a device driver or the particular device, the command and data indicating the cached unique identifier and the cached firmware version for the particular device; determining, by the device driver or the particular device, that i) the cached unique identifier matches a current unique identifier for the particular device and ii) the cached firmware version matches a current firmware version for the particular device; and completing the command at the particular device.

System and method for controlling management commands at devices

An information handling system may include at least one processor, and an information handling resource communicatively coupled to the at least one processor. The information handling system may be configured to cause the information handling resource to enter a low-power state, and further configured to cause the information handling resource to enter a full-power state. The information handling system may also be configured to cause at least one communication link of the information handling resource to remain inactive until detection of a specified event.

Systems and methods for exiting low-power states

A device hot-plug system includes a chassis. A connector is included in the chassis. A reset pin is included on the connector. A hot-plug device is configured, in response to being hot-plugged to the connector, to enter a device reset state. While in the device reset state, the hot-plug device monitors a reference clock and determines that the reference clock has been stable for a predetermined time period. In response to determining that the reference clock has been stable for a predetermined time period, the hot-plug device exits the device reset state and provides a de-assertion signal on the reset pin.
