摘要： Systems for fast views of items in file directories or file folders when interacting with a cloud-based service platform. A server in a cloud-based environment interfaces with one or more storage devices to provide storage of shared content accessible by two or more user devices. A file tree request to view the file directory or file folder of a particular sought after item is issued from an application operating on one of the user devices. Additional file tree items in a file tree hierarchy are prefetched by the cloud-based service platform. The application closes the file tree metadata stream after receiving the portion of the file tree that pertains to the particular item and before receiving the entirety of the metadata pertaining to all of the file tree metadata of all of the items in the directory or folder that contains the particular sought after item.

摘要： A multi-level cache comprises a plurality of cache levels, each configured to cache I/O request data pertaining to I/O requests of a different respective type and/or granularity. The multi-level cache may comprise a file-level cache that is configured to cache I/O request data at a file-level of granularity. A file-level cache policy may comprise file selection criteria to distinguish cacheable files from non-cacheable files. The file-level cache may monitor I/O requests within a storage stage, and may service I/O requests from a cache device.

摘要： A computer-implemented method for caching content in a cache memory device is disclosed. The method starts with receiving, at a cache manager, one or more data chunks to be cached in a cache memory device, where the one or more data chunks are retrieved from a persistent storage disk of a storage system in response to a read request of a region of a file. Then the one or more data chunks of a file extent is compressed using a predetermined compression algorithm, and the file extent is packed into a write-evict unit (WEU) maintained in a random-access memory (RAM) that has been open to store a plurality of file extents. In response to determining that the WEU is full, the cache manager writes the WEU from the RAM into the cache memory device.

摘要： Techniques for combined memory and storage tiering. For example, in one example, a method for managing placement of data in a data memory and storage system environment including at least one host computing device and at least one storage array includes the following steps. A memory and storage tier architecture is maintained across the data memory and storage system environment including one or more tiers resident on the host computing device and one or more tiers resident on the storage array. A user is enabled to: (i) specify on which of the one or more tiers resident on the host computing device and the one or more tiers resident on the storage array to store data associated with the execution of an application program; and/or (ii) specify a level of service by which the system automatically manages which of the one or more tiers resident on the host computing device and the one or more tiers resident on the storage array to store data associated with the execution of the application program.

摘要： A lease system is described herein that allows clients to request a lease to a remote file, wherein the lease permits access to the file across multiple applications using multiple handles without extra round trips to a server. When multiple applications on the same client (or multiple components of the same application) request access to the same file, the client specifies the same lease identifier to the server for each open request or may handle the request from the cache based on the existing lease. Because the server identifies the client's cache at the client level rather than the individual file request level, the client receives fewer break notifications and is able to cache remote files in more circumstances. Thus, by providing the ability to cache data in more circumstances common with modern applications, the lease system reduces bandwidth, improves server scalability, and provides faster access to data.
摘要翻译：这里描述了允许客户端向远程文件请求租赁的租赁系统，其中租赁允许使用多个句柄跨多个应用访问文件，而不需要对服务器进行额外的往返。当同一客户端上的多个应用程序（或同一应用程序的多个组件）请求访问同一个文件时，客户机为每个打开的请求指定与服务器相同的租约标识符，或者可以根据现有租约处理来自缓存的请求。因为服务器在客户端级别而不是单独的文件请求级别识别客户端的缓存，所以客户端接收到更少的中断通知，并且能够在更多情况下缓存远程文件。因此，通过提供在现代应用中更常见的情况下缓存数据的能力，租赁系统降低带宽，提高服务器可扩展性，并提供更快速的数据访问。

摘要： A device is configured to receive first data of a media file. The first data is in a first type of format. The device is further configured to extract media data and metadata from the first data, to store the media data in a first cache, and to store the metadata in a second cache. The device is also configured to determine a second type of format that is supported by a client device. The second type of format is different from the first type of format. The device is configured to retrieve the media data from the first cache, to retrieve the metadata from the second cache, to construct second data that is in the second type of format based on the media data and the metadata, and to provide the second data to the client device.
