摘要： A machine implemented method and system for communication between a computing system and an adapter is provided. An application from among a plurality of applications sends a message to the adapter with a value V. The adapter queues the message at the first storage location and writes the value V at a second storage location after the message is successfully queued at the first storage location. To determine if the message was successfully queued, the computing system reads the written value at the second storage location and compares it to the value V that was sent with the message.
摘要翻译：提供了一种用于计算系统和适配器之间的通信的机器实现的方法和系统。来自多个应用程序的应用程序以值V向适配器发送消息。适配器将消息排队在第一存储位置处，并且在消息在第一存储位置成功排队之后将值V写入第二存储位置。为了确定消息是否已成功排队，计算系统读取第二个存储位置的写入值，并将其与消息发送的值V进行比较。

摘要： Machine implemented method and system for processing a write request for a copy on write (COW) enabled write operation to write to a logical unit number (LUN) for which a replicated LUN exists is provided. An adapter coupled to a computing system and interfacing with the LUN and the replicated LUN receives the write request having an indicator indicating that the write request is for the COW enabled write operation. The adapter issues a read request to the LUN to read previous information from the LUN; temporarily stores the previous information at a memory storage location of the adapter; writes the previous information to the replicated LUN; writes the information based on the write request to the LUN; and notifies the computing system indicating that the write request for the COW enabled write operation has been completed.
摘要翻译：机器实现的方法和系统，用于处理对写入（COW）启用的写入操作的写入请求以写入存在复制LUN的逻辑单元号（LUN）。耦合到计算系统并且与LUN和复制LUN接口的适配器接收具有指示写入请求用于启用COW的写入操作的指示符的写入请求。适配器向LUN发出读取请求以从LUN读取以前的信息; 将先前的信息临时存储在适配器的存储器存储位置; 将以前的信息写入复制的LUN; 将写入请求的信息写入LUN; 并且通知计算系统指示对COW使能的写入操作的写入请求已经完成。

摘要： Machine implemented method and system is provided. The method includes sending a packet to a device by a computing system; determining an address for the packet, where an interface logic for the device determines the address; updating a location associated with the address; where the interface logic for the device updates the location; updating a bitmap value associated with the location to indicate to a processor for the device that a location associated with the address has been updated; where the interface logic updates the bitmap value; clearing the bitmap value by writing a same value that is read by the processor for the device; and processing the packet received by the device.
摘要翻译：提供了机器实现的方法和系统。该方法包括：通过计算系统将数据包发送到设备; 确定所述分组的地址，其中所述设备的接口逻辑确定所述地址; 更新与地址相关联的位置; 其中设备的接口逻辑更新位置; 更新与所述位置相关联的位图值，以向所述处理器指示所述设备与所述地址相关联的位置已被更新; 其中接口逻辑更新位图值; 通过写入与处理器为设备读取的相同值来清除位图值; 并处理由该设备接收的分组。
