Abstract: A data storage device includes a write cache, a non-volatile memory, and a controller coupled to the write cache and to the non-volatile memory. The controller is configured to, responsive to receiving a command to flush particular data from the write cache, attempt to fill a write block of data using the particular data and pending data obtained after receipt of the command.

Abstract: A storage device with a memory may implement software queueing that can supplement hardware accelerated queueing mechanisms. A software queue supplementing a hardware queue can extend the size and allow pending operations to proceed even if the hardware queue is saturated. The use of software-based queues may extend processing capacity in a hardware-accelerated front-end storage device architecture. The software queue may process excess commands that cannot be handled by a hardware queue with a limited depth.

Abstract: In one aspect, a system for indexing transactions over a plurality of communication lines is described. In various embodiments, the system includes a host controller and a plurality of storage devices in communication with one another. Each of the storage devices is configured to store data. The communication lines facilitate communications between the host controller and the plurality of storage devices. A selected one of the storage devices is configured to function as a transaction indexer to monitor the communication lines and index and store selected transaction information associated with operations that occur over the communication lines. While the host controller may be arranged to configure the transaction indexer, the transaction monitoring, indexing and storing are performed substantially automatically by the transaction indexer without requiring further instructions from the host controller.

Abstract: In one aspect, a system for indexing transactions over a shared bus is described. In various embodiments, the system includes a host controller and a plurality of storage devices in communication with the bus. Each of the storage devices is configured to store data. The bus facilitates communications between the host controller and the plurality of storage devices. A selected one of the storage devices is configured to function as a transaction indexer to monitor the bus and index and store selected transaction information associated with operations that occur over the bus. While the host controller may be arranged to configure the transaction indexer, the transaction monitoring, indexing and storing are performed substantially automatically by the transaction indexer without requiring further instructions from the host controller.
