摘要： A bridge in a file server provides a direct link to data storage devices in satisfaction of data requests. The file server has one or more function-specific processors, including network processors (NPs) and file storage processors (FSPs), all operating in parallel and communicating over an interconnect bus. Each FSP is also connected to one or more disk controllers which in turn manage one or more data storage devices. To minimize local bus contention between data storage devices and network communications, separate internal buses are provided in the FSP, one internal bus connected to the interconnect bus for network communications and one internal bus connected to disk controllers for performing I/O operations on data storage devices. The bridge provides a path between the FSP's internal buses so that, for disk access requests, data from a particular data storage device may be sent by the disk controller via the bridge over the interconnect bus to the NP servicing the request with minimal involvement of the local FSP processor.
摘要翻译：文件服务器中的一个桥接器可以直接链接到满足数据请求的数据存储设备。文件服务器具有一个或多个功能特定的处理器，包括网络处理器（NP）和文件存储处理器（FSP），所有这些处理器都通过并行运行并通过互连总线进行通信。每个FSP还连接到一个或多个磁盘控制器，磁盘控制器又管理一个或多个数据存储设备。为了最小化数据存储设备和网络通信之间的局部总线争用，FSP中提供单独的内部总线，一条内部总线连接到互连总线进行网络通信，一条内部总线连接到磁盘控制器，用于对数据存储执行I / O操作设备。该桥提供了FSP内部总线之间的路径，因此，对于磁盘访问请求，来自特定数据存储设备的数据可以由磁盘控制器通过互连总线上的桥发送到NP，以最少的参与本地FSP处理器。
