摘要： An apparatus and method are provided for connecting a host Enterprise System Connection Architecture (ESCON) Input/Output (I/O) interface to a cache of a data storage system. The apparatus includes (a) a set of at least 4 pipelines, each pipeline being coupled on a first end to the host ESCON I/O interface and being coupled on a second end to the cache, (b) a plurality of line processors, each line processor controlling one or more of the pipelines of the set of pipelines, and (c) in each pipeline, a protocol engine, the protocol engine configured to distinguish user data from frame header data and separate the user data from the frame header data for transport over the pipeline.

摘要： A shared resources service processor facilitates messaging between line processors and provides a single point of contact for a user interfacing with line processor(s), for example in a storage system interface. Shared memory is divided into “mailboxes” that are used to communicate between the line processors and the service processor. The service processor issues a system management interrupt to any or all of the line processors. This interrupt indicates to the line processor(s) that it should go out to the shared memory and read its respective mailbox. In operation, the service processor can deliver a message, i.e. command, to a line processor's mailbox, for example to tell a line processor to go off-line or on-line. The service processor will write the command into the mailbox and then assert the system management interrupt on the appropriate line processor that it wants to read the mailbox. The line processor receiving the interrupt will take the interrupt vector, read the mailbox, interpret the command and deliver the appropriate response to the mailbox. The line processor(s) conserves backplane bandwidth by selectively consolidating selected tasks onto the service processor to reduce the number of accesses to the backplane.
摘要翻译：共享资源服务处理器促进线路处理器之间的消息传送，并为例如在存储系统接口中与线路处理器接口的用户提供单点联系。共享内存分为用于在线路处理器和服务处理器之间进行通信的“邮箱”。服务处理器向任何或所有线路处理器发出系统管理中断。该中断向线路处理器指示它应该出去共享存储器并读取其相应的邮箱。在操作中，服务处理器可以向线路处理器的邮箱传送消息，即命令，例如告诉线路处理器离线或在线。服务处理器会将命令写入邮箱，然后在要读取邮箱的相应线路处理器上断开系统管理中断。接收中断的线路处理器将采取中断向量，读取邮箱，解释命令并将相应的响应传递给邮箱。线路处理器通过选择性地将选定的任务整合到服务处理器来减少对背板的访问次数来节省背板带宽。
