摘要： This document describes techniques for storing virtual disk payload data. In an exemplary configuration, each virtual disk extent can be associated with state information that indicates whether the virtual disk extent is described by a virtual disk file. Under certain conditions the space used to describe a virtual disk extent can be reclaimed and state information can be used to determine how read and/or write operations directed to the virtual disk extent are handled. In addition to the foregoing, other techniques are described in the claims, figures, and detailed description of this document.

摘要： This document describes techniques for effecting a virtual disk. In an exemplary configuration, a virtual disk file can be associated with a log that acts as both a log and a check point record. When a log entry is generated, information that identifies the tail can be stored therein. This information can be used in the event that virtual disk file is improperly closed, i.e., a crash or power failure occurs, to discover a sequence of log entries to replay. In addition to the foregoing, other techniques are described in the claims, detailed description, and figures.
摘要翻译：本文档描述了影响虚拟磁盘的技术。在示例性配置中，虚拟磁盘文件可以与充当日志和检查点记录的日志相关联。当生成日志条目时，可以存储标识尾部的信息。在虚拟磁盘文件不正确关闭的情况下，即发生崩溃或电源故障的情况下，可以使用此信息来发现要重播的日志条目序列。除了上述之外，在权利要求书，详细描述和附图中描述了其它技术。

摘要： In an exemplary embodiment, a virtual disk file can be assigned an identifier and a virtual disk files that is dependent on the virtual disk file can include a copy of the identifier. In the instance that the virtual disk file is opened and data is modified that causes the contents of a virtual disk extent to change the identifier can be changed. If the virtual disk file and the dependent virtual disk file are used to instantiate a virtual disk the difference between identifiers can be detected, which is indicative of the fact that the virtual disk may be corrupted. Other techniques are described in the detailed description, claims, and figures that form a part of this document.

摘要： Aspects of the subject matter described herein relate to virtualization and offload reads and writes. In aspects, an offload read allows a requestor to obtain a token that represents data while an offload write allows the requestor to request that the data (or a part thereof) represented by a token be logically written. Offload reads and writes may be used to perform various actions for virtual environments.

摘要： Aspects of the subject matter described herein relate to offload reads and writes. In aspects, a requestor that seeks to transfer data sends a request for a representation of the data. In response, the requestor receives one or more tokens that represent the data. The requestor may then provide one or more of these tokens to a component with a request to write data represented by the one or more tokens. In some exemplary applications, the component may use the one or more tokens to identify the data and may then read the data or logically write the data without additional interaction with the requestor. Tokens may be invalidated by request or based on other factors.

摘要： Described are embodiments which allow token-based file operations. The client may request a special offload file operation that is formatted according to a file access protocol. The file operation may be an offload read operation or an offload write operation. In an offload read operation, the client requests that data be logically read from a stored file, or a portion thereof. In response, the file server provides a response that includes a token that represents the logically read data. In some embodiments, the file server may return a response with a token that represents less than all of the requested data if for some reason it cannot provide a token that represents all of the data. The token can then be used by the client in a subsequent offload write operation. In embodiments, the tokens represent immutable data that can be safely and securely used across servers and clients.
摘要翻译：描述了允许基于令牌的文件操作的实施例。客户端可以请求根据文件访问协议格式化的特殊卸载文件操作。文件操作可以是卸载读取操作或卸载写入操作。在卸载读取操作中，客户端请求从存储的文件或其一部分逻辑地读取数据。作为响应，文件服务器提供包括表示逻辑读取数据的令牌的响应。在一些实施例中，如果由于某些原因它不能提供表示所有数据的令牌，则文件服务器可以返回具有表示小于所有请求的数据的令牌的响应。然后，客户端可以在后续的卸载写入操作中使用令牌。在实施例中，令牌表示可以跨服务器和客户机安全和安全地使用的不可变数据。
