Abstract: A RAID storage-device-assisted RMW system includes a RAID primary data drive that retrieves second primary data via a DMA operation from a host system, and XOR's it with its first primary data to produce first interim parity data that it writes via a DMA operation to a RAID parity data drive. The RAID parity data drive XOR's its first parity data and the first interim parity data to produce second parity data that overwrites the first parity data. The RAID parity data drive also performs GF operations on the first interim parity data and its second interim parity data and XOR's the results to produce interim Q data that it writes via a DMA operation to a RAID Q data drive. The RAID Q data drive XOR's its first Q data and the interim Q data to produce second Q data that overwrites the first Q data.

Abstract: A management controller sends a first firmware measurement request to verify integrity of a device. The first firmware measurement request is sent at initial power on of the device, and is sent subsequent to negotiating a secure session between the management controller and the device. The management controller verifies a first firmware measurement in a first firmware measurement response to the first firmware measurement request prior to storing the first firmware measurement, and sends a heartbeat request to the device to monitor for a device state change. The management controller may receive a heartbeat acknowledgement from the device in response to the heartbeat request, wherein the heartbeat acknowledgement includes an indication of the device state change. In response to the receipt of the heartbeat acknowledgment that includes the device state change, the management controller sends a second firmware measurement request to the device.

Abstract: An autonomous RAID data storage device locking system includes first RAID data storage device(s) that store data included in a data stripe, and that are coupled to a second RAID data storage device. The second RAID data storage device receives a command to perform a data update operation on a subset of data included in the data stripe, and transmits a locking request to each first RAID data storage device.

The second RAID data storage device then transmits an unlocking request to each first RAID data storage device to cause them to unlock, and transmits a completion communication that indicates that the data update operation has been performed.
