    摘要: Disclosed are apparatus and methods for discovering topology in a storage area network having a plurality of VSANs in a network fabric is disclosed. The VSANs include a first VSAN having a plurality of network devices. The method includes the following operations: (a) defining a first one of the network devices of the first VSAN as a Topology Update (TU) Owner, wherein the other network devices of the first VSAN are not defined as TU Owners, (b) at the first network device, receiving data that indicates a topology change in the first VSAN, (c) at the first network device, generating or updating one or more TU database(s) for the plurality of VSANs of the network fabric based on the received topology change, and (d) the first network device causing the topology change to be propagated in the form of a Topology Update across the network fabric to network devices in the plurality of VSANs of such network fabric.

    摘要: Disclosed are apparatus and methods for facilitating communication between two devices from two different VSANs by propagating each device's presence from a first VSAN to the other device's different VSAN using a network address translation (NAT) mechanism. For instance, a first device, such as a host H1, from VSAN_A is allowed to access data from a second device, such as disk D1, of VSAN_B by propagating D1's presence into VSAN_A and H1's presence into VSAN_B. This awareness is accomplished by propagating an identifier for each device into the edge VSAN of the other device, as well as into any transit VSAN. So as to not duplicate identifiers in any one of the VSANs, a device's presence is propagated into a particular VSAN by assigning an unused domain for use by such device in the particular VSAN.

    摘要: A method for summarizing capabilities in a hierarchically arranged data center includes receiving capabilities information, wherein the capabilities information is representative of capabilities of respective nodes at a first hierarchical level in the hierarchically arranged data center, clustering nodes based on groups of capabilities information, generating a histogram that represents individual node clusters, and sending the histogram to a next higher level in the hierarchically arranged data center. Relative rankings of capabilities may be used to order a sequence of clustering operations.

    摘要: Techniques are disclosed for zoning information to be shared with an NPIV proxy device or an NPV device such as a blade switch in a blade chassis. Doing so allows the NPV device to enforce zoning locally for the attached server blades and virtualized systems. The NPV device may learn zoning rules using Fiber Channel name server queries and registered state change notifications. Additionally, the NPV device may snoop name server queries to retrieve zoning information (or state change messages) without using the zoning change protocols and without consuming a Fiber Channel domain from the Fiber Channel fabric.
