摘要： Initiators and targets in a storage area network are presented as virtualized devices by a virtualization engine. An initiator accesses a virtualized target as though it was accessing a physical target. A target accesses a virtualized initiator as though it was accessing a physical initiator. A virtualization engine performs port World Wide Name (WWN) and FCID mapping to allow continued access to virtual initiators and virtual targets even if a particular physical initiator or physical target fails and the secondary is made active.

摘要： A method and apparatus that includes processing for providing multi-cast transmissions within a data network begins by determining, for a source virtual network, a list of downstream virtual sub-networks for multi-cast traffic based on a multi-cast routing protocol. The processing then continues by determining multi-cast group membership on as per downstream virtual sub-network, edge device, and port basis. The process continues when a data packet is received via the source virtual network. The processing then continues by generating a multi-cast session table entry based on the list of downstream virtual sub-networks and the multi-cast group membership. The process continues by establishing virtual connections between the source virtual network and edge devices coupled to virtual sub-networks identified in the list of downstream virtual sub-networks. Having generated the virtual connections, the processing continues by downloading the multi-cast session table to the edge devices. The edge devices utilize the multi-cast session table entry to determine where the received data packets are to be forwarded.
摘要翻译：一种包括用于在数据网络内提供多播传输的处理的方法和装置，首先通过基于多播路由协议来确定源虚拟网络中用于多播流量的下游虚拟子网的列表。然后通过根据下游虚拟子网络，边缘设备和端口基础确定多播组成员资格来继续处理。当通过源虚拟网络接收到数据分组时，该过程继续。然后通过基于下游虚拟子网络和多播组成员资格的列表生成多播会话表条目来继续处理。该过程通过在源虚拟网络和耦合到在下游虚拟子网络列表中标识的虚拟子网络的边缘设备之间建立虚拟连接来继续。在生成虚拟连接之后，通过将多播会话表下载到边缘设备来继续处理。边缘设备利用多播会话表条目来确定接收到的数据分组将在哪里被转发。

摘要： The present invention describes various mechanisms which may be used for improving SAN device interoperability enforcement techniques implemented in SAN or Fiber Channel networks. In one implementation, the technique of the present invention allows a SAN to automatically enforce interoperability requirements between devices connected to a SAN by utilizing SAN zoning technology to implement one or more novel types of “smart” zones having different, customizable attributes. In one implementation, a first device and second device of the SAN may be automatically identified as being non-interoperable. The first device and the second device may then be included as members of a negative zone having a first associated negative zone attribute prohibiting communication between members of the first negative zone.

摘要： Techniques are provided for receiving at a proxy device in a network, a login request from a source device, e.g., a Fiber Channel server in a server virtualization cluster, to access a destination device, a Fiber Channel storage array. The source device does not or need not have direct access to the destination device. A response to the login request is sent that is configured to appear to the source device that the response is from the destination device. The proxy device logs into the destination device on behalf of the source device to obtain access to the destination device. The proxy device receives first network traffic frames associated with a service flow between the source device and the destination device from the source device that are destined for the destination device. Information is overwritten within the first network traffic frames such that the first network traffic frames appear to originate from the proxy device when transmitted to the destination device. The first network traffic frames are transmitted from the proxy device to the destination device. Techniques are also provided herein for performing similar operations on frames sent from the destination device to the proxy device.
