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相邻块,并且所述读取请求包括文件块号。 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。
