摘要： Systems and techniques for control of storage device power states are described herein. In some embodiments, a control system for a storage device of a computing device may include receiver logic to receive a proximity signal indicative of a distance of a user from a proximity sensor, transition logic to determine that the proximity signal satisfies out-of-proximity criteria and generate an out-transition signal based at least in part on the determination that the proximity signal satisfies the out-of-proximity criteria, and state-change logic to cause a change in a power state of the storage device from a first power state to a second power state, in response to the out-transition signal, wherein the storage device consumes less power in the second power state than in the first power state. Other embodiments may be described and/or claimed.

摘要： A method and system to perform caching based at least on one or more file-level heuristics. The caching of a storage medium in a caching device is performed by a cache policy engine. The cache policy engine receives file-level information of input/output access of data of the storage medium and caches or evicts the data of the storage medium in the caching device based on the received file-level information. By utilizing information about the files and file operations associated with the disk sectors or logical block addresses of the storage medium, the cache policy engine can make a better decision on the data selection of the storage medium to be cached in or evicted from the caching device in one embodiment of the invention. Higher cache hit rates can be achieved and the performance of the system utilizing the cache policy engine is improved.
摘要翻译：至少基于一个或多个文件级启发式方法和系统执行缓存。缓存设备中的存储介质的缓存由高速缓存策略引擎执行。高速缓存策略引擎接收存储介质的数据的输入/输出访问的文件级信息，并基于接收到的文件级信息来高速缓存或者将高速缓存设备中的存储介质的数据移出。通过利用关于与存储介质的磁盘扇区或逻辑块地址相关联的文件和文件操作的信息，高速缓存策略引擎可以更好地决定要缓存到缓存设备或从高速缓存设备移出的存储介质的数据选择在本发明的一个实施例中。可以实现更高的缓存命中率，并提高利用缓存策略引擎的系统的性能。

摘要： A controller maintains exposed and unexposed locations of a first storage device and a second storage device. In response to receiving a request a perform a write operation to write data in locations that span the first storage device and the second storage device, the controller atomically writes an entirety of the data in the unexposed locations of the first storage device.
