Abstract: Technologies are provided for supporting multi-actuator storage device access using logical addresses. Separate sets of logical addresses (such as logical block addresses) can be associated with different actuators of a storage device. For example, a first set of logical addresses can be assigned to storage locations on one or more storage media that is/are accessible using a first actuator of the storage device and a second set of logical addresses can be assigned to storage locations on one or more storage media that is/are accessible using a second actuator of the storage device. The storage device can receive a data access request containing a logical address and can identify a logical address set to which the logical address belongs. The storage device can use an actuator associated with the logical address set to access a storage location assigned to the logical address.

Abstract: Technologies are provided for a storage device data move command. A storage device can be configured to receive a data move (or garbage collection) command and, responsive to receiving the command, move data from one zone of the storage device (or range of storage locations within the storage device) to another zone (or another range of storage locations) within the storage device. The command can comprise a source zone identifier and a target zone identifier. The storage device can read data from a storage zone associated with the source zone identifier and write the data to another storage zone associated with the target zone identifier. The identifiers can include ranges of storage location addresses within the separate storage zones. In at least some embodiments, a host bus adapter can be configured to support the data move (or garbage collection) command for a storage device attached to the host bus adapter.

Abstract: Technologies are provided for secure sanitization of a storage device. A storage device can be configured to support an operational mode, into which the storage device is placed by default, and in which requests to cryptographically erase the storage device are rejected. The storage device can support a separate sanitization mode in which a request to cryptographically erase the storage device will be processed. Access to the sanitization mode can be restricted to trusted sources (such as a boot firmware of a computer connected to the storage device). The storage device can be configured to reject a command to place the storage device in the sanitization mode, unless the command is received during an initialization of the storage device. In at least some embodiments, the storage device can reject data access commands while it is in the sanitization mode.

Abstract: Technologies are provided for dynamically changing a size of a cache region of a storage device. A storage device controller writes data to the cache region of the storage device using a particular storage format. The storage device controller then migrates the cached data to a storage region of the device, where the data is written using a different storage format. A dynamic cache manager monitors input and output activity for the storage device and dynamically adjusts a size of the cache region to adapt to changes in the input and/or output activity. The dynamic cache manager can also adjust a size of the storage region. The storage device controller can automatically detect that the storage device has dynamic cache support and configure the storage device by creating the cache region and the storage region on the device.

Abstract: Technologies are provided for supporting storage device write barriers. A host computer can be configured to transmit a write barrier command to a storage device to indicate that one or more data access commands should be processed before one or more other data access commands are processed. For example, a host computer can transmit one or more data access commands to a storage device. The host computer can then transmit a write barrier command to the storage device. The storage device can be configured to receive the write barrier command and to associate a write barrier with the one or more data access commands. The host computer can continue to transmit additional data access commands to the storage device. However, the storage device will not process the additional data access commands until after the one or more data access commands associated with the write barrier have been processed.

Abstract: Technologies are provided for supporting storage device write barriers. A storage device can be configured to associate a data access command with a write barrier. The write barrier can be used to indicate that one or more data access commands should be processed before one or more other data access commands are processed. For example, a host computer can transmit one or more data access commands to a storage device. The storage device can determine that the one or more data access commands are associated with a write barrier. The host computer can continue to transmit additional data access commands to the storage device. However, the storage device will not process the additional data access commands until after the one or more data access commands associated with the write barrier have been processed.

Abstract: Technologies are provided for partially updating shingled magnetic recording (SMR) zones in SMR storage devices. An SMR storage device can receive and process a command to update a write pointer for an SMR zone to point to an arbitrary write position within the SMR zone. A partial SMR zone update command can be received and processed to modify part of the data stored in the SMR zone. A write position within the SMR zone where data to be modified is stored can be identified. Data stored in the SMR zone following the identified write position can be read to a temporary location and modified. A write pointer for the SMR zone can be updated to point to the identified write position. The modified data can then be written to the SMR zone, starting at the write position identified by the write pointer, or to another SMR zone of the storage device.

Abstract: Technologies are provided for bypassing control logic of an electronic device and writing a trusted firmware to a storage location of the device. The device can comprise a bypass communication channel that, when enabled, allows a connected host computer to access a storage medium and/or onboard memory of the device without using the device's control logic. A device controller can be configured to receive a firmware update mode command from a connected host computer and to enable the bypass communication channel. In at least some embodiments, the controller is configured to reject the update mode command unless it is received as part of an initial communication from the host computer during a boot sequence of the electronic device. In a different or further embodiment, the controller is configured to determine that the command is authorized before enabling the bypass communication channel.
