    摘要： Methods, systems, and computer program products for performing an input/output (I/O) operation that includes a virtual drain. According to one aspect, the subject matter described herein includes a method for performing an input/output operation that includes a virtual drain. The method includes receiving a request to perform a consistent operation involving a storage entity, and in response to receiving the request: arresting write requests to the storage entity; performing a virtual drain, where performing a virtual drain includes identifying, and indicating as deferred, pending writes to the storage entity; performing the consistent operation; releasing write requests to the storage entity; and processing each deferred write using information that is associated with the write and that describes the context in which the write request was accepted.

    摘要： A system, device, and method for interprocessor communication in a computer system utilizes a special Message Passing Service (MPS) to provide interprocessor communications. The MPS enables a client application running on one processor in a computer to communicate with a target application running a different processor in the same or a different computer. In order for the client application to communicate with the target application, the client application establishes a session to the target application over an existing communication link using the MPS. The MPS provides for both synchronous and asynchronous communication services. When the client application establishes the session to the target application, the client application specifies, among other things, a “callback” routine. The MPS invokes the “callback” routine to report certain asynchronous events to the client application. The MPS blocks the client application during certain synchronous operations so that the client application does not proceed until the synchronous operation is completed.

    摘要翻译： 用于计算机系统中的处理器间通信的系统，设备和方法利用特殊的消息传递服务（MPS）来提供处理器之间的通信。 MPS使得在计算机中的一个处理器上运行的客户端应用程序与在相同或不同的计算机中运行不同处理器的目标应用程序进行通信。 为了使客户端应用程序与目标应用程序通信，客户端应用程序使用MPS通过现有通信链路建立与目标应用程序的会话。 MPS提供同步和异步通信服务。 当客户端应用程序建立到目标应用程序的会话时，客户端应用程序除其他外指定了“回调”例程。 MPS调用“回调”例程来向客户端应用程序报告某些异步事件。 在某些同步操作期间，MPS阻止客户端应用程序，以便客户端应用程序在同步操作完成之前才会继续。

    摘要： An architecture and apparatus for atomic operations across multi-volume or multi-LUNs in a data storage environment. It is difficult to manage data storage and replication operations occurring across such multi-LUNs. The architecture and apparatus embodiments of the invention overcome these deficiencies and facilitate data storage management and replication operations through library initializations in response to host I/O requests to complete atomic operations. Accordingly, the invention ensures the integrity of the data being managed without introducing significant cost or overhead.

    摘要： This invention enables managing data consistency between different data volumes by managing I/O traffic in a data storage environment. A methodology for managing data consistency, in accordance with the principles of the invention, comprises the steps of arresting processing of I/O traffic during an administrative operation, queuing any I/O that follow the arresting step in a queuing data structure and processing each queued I/O until the I/O processing is completed. Certain implementations of the invention include a system, a computer program product, or an apparatus, wherein each embodiment is configured for carrying out the steps involved in the methodology.
