Abstract: A request is received to remove duplicate data. A log data container associated with a storage volume in a storage server is accessed. The log data container includes a plurality of entries. Each entry is identified by an extent identifier in a data structures stored in a volume associated with the storage server. For each entry in the log data container, a determination is made if the entry matches another entry in the log data container. If the entry matches another entry in the log data container, a determination is made of a donor extent and a recipient extent. If an external reference count associated with the recipient extent equals a first predetermined value, block sharing is performed for the donor extent and the recipient extent. A determination is made if the reference count of the donor extent equals a second predetermined value. If the reference count of the donor extent equals the second predetermined value, the donor extent is freed.

Abstract translation: 收到请求以删除重复的数据。 访问与存储服务器中的存储卷相关联的日志数据容器。 日志数据容器包括多个条目。 每个条目由存储在与存储服务器相关联的卷中的数据结构中的盘区标识符标识。 对于日志数据容器中的每个条目，确定条目是否匹配日志数据容器中的另一个条目。 如果条目与日志数据容器中的另一个条目匹配，则确定捐赠者范围和受众范围。 如果与接收者范围相关联的外部参考计数等于第一预定值，则对捐赠者范围和接受者范围执行块共享。 如果供体范围的参考计数等于第二预定值，则确定。 如果供体范围的参考计数等于第二预定值，则供体范围被释放。

Abstract: An extent-based storage architecture is implemented by a storage server receiving a read request for an extent from a client, wherein the extent includes a group of contiguous blocks and the read request includes a file block number. The storage server retrieves an extent identifier from a first sorted data structure, wherein the storage server uses the received file block number to traverse the first sorted data structure to the extent identifier. The storage server retrieves a reference to the extent from a second sorted data structure, wherein the storage server uses the retrieved extent identifier to traverse the second sorted data structure to the reference, and wherein the second sorted data structure is global across a plurality of volumes. The storage server retrieves the extent from a storage device using the reference and returns the extent to the client.

Abstract translation: 基于范围的存储架构由存储服务器实现，所述存储服务器从客户端接收对范围的读取请求，其中所述扩展区包括一组连续的块，并且所述读请求包括文件块号。 存储服务器从第一排序数据结构检索区段标识符，其中存储服务器使用接收到的文件块号来遍历第一排序数据结构到区段标识符。 存储服务器从第二排序数据结构检索对范围的引用，其中存储服务器使用所检索的扩展名标识符遍历到引用的第二排序数据结构，并且其中第二排序数据结构在多个卷中是全局的 。 存储服务器使用引用从存储设备检索范围，并将该范围返回给客户端。

Abstract: The data path in a network storage system is streamlined by sharing a memory among multiple functional modules (e.g., N-module and D-module) of a storage server that facilitates symmetric access to data from multiple clients. The shared memory stores data from clients or storage devices to facilitate communication of data between clients and storage devices and/or between functional modules, and reduces redundant copies necessary for data transport. It reduces latency and improves throughput efficiencies by minimizing data copies and using hardware assisted mechanisms such as DMA directly from host bus adapters over an interconnection, e.g. switched PCI-e "network". This scheme is well suited for a "SAN array" architecture, but also can be applied to NAS protocols or in a unified protocol-agnostic storage system. The storage system can provide a range of configurations ranging from dual module to many modules with redundant switched fabrics for I/O, CPU, memory, and disk connectivity.

Abstract translation: 通过在存储服务器的多个功能模块（例如，N模块和D模块）中共享存储器来简化网络存储系统中的数据路径，该存储服务器有助于对来自多个客户端的数据的对称访问。 共享存储器存储来自客户端或存储设备的数据，以促进客户端和存储设备之间和/或功能模块之间的数据通信，并减少数据传输所需的冗余副本。 它通过最小化数据副本并使用诸如DMA之类的硬件辅助机制直接从主机总线适配器（例如，互连）来减少延迟并提高吞吐量效率。 切换PCI-e“网络”。 该方案非常适用于“SAN阵列”架构，也可应用于NAS协议或统一协议无关的存储系统。 存储系统可以提供从双模块到多模块的一系列配置，具有用于I / O，CPU，内存和磁盘连接的冗余交换架构。
