Abstract: A thread of a storage server determines that a command to modify a reservation record which comprises access permissions of an object stored at the server has been received. A version of the record is stored in an in-memory cache. The thread acquires a first lock associated with the record in exclusive mode, and a second lock in shared mode. The thread reads the cached version, constructs a modified version indicated in the command, and releases the second lock without updating the cache. After entries representing the modified version are stored in an operations journal, the thread acquires the second lock in exclusive mode and updates the cache. The thread then releases both locks. An indication that the command has succeeded is provided without verifying that the second version is stored at a metadata store.

The prosthesis is configured to self-expand for deployment in the heart when released from the delivery catheter.

Abstract: Reset operations impact data storage device latency. Every reset operation involves flushing cache data to the memory device and resetting the front end application specific integrated circuit (ASIC) accelerator/host interface module (HIM). Multiple resets that are performed consecutively waste valuable data storage device resources due to the duplication of the operations that every reset operation performs. Data storage device latency can be improved, as can data storage device idle time, by combining reset operations and removing duplicative operations. For example, for two different, but consecutive reset operations, the reset operations are performed by flushing the cache data and resetting the ASIC accelerator/HIM only once rather than repeat the operations for each reset operation. In so doing, the two reset operations complete reset operations faster than would otherwise occur.
