Abstract: A cache space management method and apparatus are disclosed. In the method, first, a hit rate of the read cache of the storage system is obtained; and then, a size of the read cache and a size of the metadata cache are adjusted based on the hit rate of the read cache. In the foregoing technical solution, the size of the read cache and the size of the metadata cache are dynamically adjusted by using the hit rate of the read cache as a decision factor. For example, when the hit rate of the read cache is relatively high, the size of the read cache may be increased.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for proximity-based access. In some implementations, a computing device detects an attempt to access the computing device while the computing device is in a secured state. In response to detecting the attempt to access the computing device, the computing device sends a first message to a server system over a network. After sending the message, the computing device receives a second message from the server system over the network, the second message comprising authentication data for the computing device. The computing device determines that a mobile device that was previously designated as an authentication factor for accessing the computing device is located within a predetermined level of proximity of the computing device, and the computing device grants access to the computing device.
