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.
摘要翻译：本文描述的主题的方面涉及卸载读取和写入。在方面，寻求传输数据的请求者发送对数据表示的请求。作为响应，请求者接收表示数据的一个或多个令牌。然后，请求者可以向组件提供写入由一个或多个令牌表示的数据的请求的一个或多个令牌。在一些示例性应用中，组件可以使用一个或多个令牌来识别数据，然后可以读取数据或逻辑地写入数据，而无需与请求者的额外交互。令牌可能被请求或基于其他因素无效。

摘要： Aspects of the subject matter described herein relate to an offload provider. In aspects, an offload provider may provide a token that represents data. The offload provider may be expected to ensure that the data the token represents will not change while the token is valid. The offload provider may take actions to ensure the immutability of the data. The actions may be taken, for example, in conjunction with receiving an offload read and/or offload write, and/or in conjunction with receiving another write that, if allowed to proceed, would otherwise change the data represented by the token.

摘要： Aspects of the subject matter described herein relate to a zero token. In aspects, a zero token may be used to represent one or more zeroes in an offload write command. A component receiving an offload write command with the zero token is free to write the zeroes in a variety of ways including, for example, changing data structures the component uses to represent the zeroes, issuing another command that writes zeroes, writing physical zeroes, and so forth. A component receiving an offload write command with the zero token does not need to verify that the zero token was obtained from a successful offload read or that the zero token is still valid. In response to an offload read request, a component may provide the zero token to represent all or a portion of the data associated with the offload read request.
摘要翻译：本文描述的主题的方面涉及零令牌。在方面，可以使用零令牌来表示卸载写入命令中的一个或多个零。使用零令牌接收卸载写入命令的组件可以以各种方式自由写入零，包括例如改变组件用于表示零的数据结构，发出另一个写入零的命令，写入物理零点和等等。使用零令牌接收卸载写入命令的组件不需要验证是否从成功卸载读取获得零令牌，或者零令牌仍然有效。响应于卸载读取请求，组件可以提供零令牌来表示与卸载读取请求相关联的数据的全部或一部分。

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。

摘要： The storage of data sets in a storage set (e.g., data sets written to hard disk drives comprising a RAID array) may diminish the performance of the storage set through non-sequential writes, particularly if the storage devices promptly write data sets that are followed by sequentially following data sets. Additionally, storage sets may exhibit inconsistencies due to non-atomic writes of data sets and verifiers (e.g., checksums) and an intervening failure, such as an occurrence of the RAID write hole. Instead, data sets and verifiers may first be written to a stored on the nonvolatile media of a storage device before being committed to the storage set. Such writes may be sequentially written to the journal, irrespective of the locations of the data sets in the storage set; and recovery of a failure may simply involve re-committing the consistent records in the journal to correct incomplete writes to the storage set.
摘要翻译：将数据集存储在存储集中（例如，写入包含RAID阵列的硬盘驱动器的数据集）可能会通过非顺序写入来降低存储集的性能，特别是如果存储设备及时写入遵循的数据集通过顺序跟随数据集。此外，由于数据集和验证器（例如，校验和）的非原子写入以及诸如RAID写入孔的发生的中间故障，存储器组可能表现出不一致。相反，在提交到存储集之前，数据集和验证器可以首先被写入到存储设备的非易失性介质上。这样的写入可以顺序地写入日志，而不管存储集中的数据集的位置如何; 并且恢复故障可能只是简单地涉及在日志中重新提交一致的记录来纠正对存储集的不完整写入。

摘要： The representation of storage devices on computers (e.g., as logical volumes) may be complicated by the pooling of multiple storage devices in order to apply redundancy plans such as mirroring and checksumming. Presented herein is a storage device driver configured to operate as a storage device interface generating representations of the storage regions of the storage devices; to claim those regions as a storage controller; and to expose pooled storage regions as logical disks. Additionally, the storage device driver may support the inclusion of storage devices in a cluster, comprising nodes that may be appointed as managers of the storage pool configuration; as managers of the storage devices; as owners having exclusive read/write access to the storage pool or cluster resources; and as cluster resource writers having excusive write access to a cluster resource. The nodes of the cluster may interoperate to share the storage devices while avoiding write conflicts.
摘要翻译：存储设备在计算机上的表示（例如，作为逻辑卷）可能通过汇集多个存储设备而变得复杂，以便应用诸如镜像和校验和之类的冗余计划。这里呈现的是存储设备驱动器，其被配置为作为产生存储设备的存储区域的表示的存储设备接口来操作; 要求这些地区作为存储控制器; 并将池化的存储区域公开为逻辑磁盘。此外，存储设备驱动程序可以支持在群集中包括存储设备，包括可被指定为存储池配置的管理者的节点; 作为存储设备的管理者; 作为具有对存储池或集群资源的独占读/写访问权限的所有者; 以及作为群集资源编写者具有对集群资源的可读写入访问权限。集群的节点可以互操作以共享存储设备，同时避免写入冲突。
