  • Patent number: 11314437
    Abstract: Technologies are provided for storing data by alternating the performance of data write operations using multiple clusters of storage devices. Data is written to internal buffers of storage devices in one cluster while data stored in buffers of storage devices in another cluster is transferred to the storage devices' permanent storages. When available buffer capacity in a cluster falls below a specified threshold, data write commands are no longer sent the cluster and the storage devices in the cluster transfer data stored in their buffers to their permanent storages. While the data is being transferred, data write commands are transmitted to other clusters. When the data transfer is complete, the storage devices in the cluster can be scheduled to receive data write commands again. A cluster can be selected for performing a given data write request by matching the attributes of the cluster to parameters of the data write request.

  • Patent number: 11308992
    Abstract: Technologies are provided for accessing a physical location of a storage medium reader of a storage device. A computing device can transmit a request for the storage medium reader's physical location. The storage device can determine the physical location of the storage medium reader and transmit the location to the computing device. The computing device can use the physical location of the storage medium reader to determine an expected latency for retrieving one or more stored data items. The computing device can transmit a command to change the physical location of the storage medium reader, for example by changing a location of the storage medium reader with respect to a given storage medium and/or changing a storage medium that is accessed by the storage medium reader. The computing device can control the placement of the storage medium reader in order to optimize retrieval of data items from the storage device.

  • Patent number: 11301164
    Abstract: A multi-actuator storage device includes separate actuators that can be used to access a storage medium. A property of a request can be analyzed to determine which actuator to use to access data associated with the request. For example, high-priority requests can be handled by an actuator designated for random I/O requests, whereas low-priority requests can be handled by an actuator designated for sequential I/O requests. Writes can be treated as low-priority requests. In a particular embodiment, a priority bit can be used to determine which actuator is used to access the data.

  • Publication number: 20210397346
    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.

  • Patent number: 11194486
    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.

  • Patent number: 11106369
    Abstract: Technologies are provided for retrieving service level indicators (SLIs) for storage devices, prioritizing data access using the SLIs, and scheduling storage device maintenance based on the SLIs. A host computer can retrieve an SLI for a storage device and determine, using the SLI, whether the storage device is performing service and maintenance operations and/or whether the storage device is in need of performing service and maintenance operations. The host computer can retrieve SLIs for multiple storage devices storing data redundantly and prioritize using the storage devices to access the data based on the SLIs. If the host computer determines that a storage device is in need of maintenance, based on its SLI, the host computer can schedule the storage device for maintenance and divert data access requests to other storage devices until the maintenance is complete.

  • Patent number: 10923152
    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.

  • Patent number: 10877830
    Abstract: Technologies are provided for remotely destroying a storage device. One or more commands can be transmitted to a storage device to render the storage device inoperable. The storage device can be placed in a retired operation mode, in which the storage device cannot process data access commands. Data stored in the storage device can be sanitized to prevent it from being retrieved. Code modules that are responsible for processing data access commands can be erased from a firmware of the storage device. The storage device can perform operations to render a storage medium of the storage device inoperable. While in the retired mode, the storage device can process an inquiry command to retrieve information about the storage device from the firmware of the storage device. The retrieved information can be used to generate a digital destruction certificate that can be provided to a supplier of the storage device.
