    摘要: An apparatus, system, and method are disclosed for distributing configuration parameters. The present invention includes one or more storage devices configured to store data, a first DHCP server configured to process DHCP messages and redirect communications regarding configuration parameters for the storage devices to a second DHCP server, and a configuration datastore configured to store configuration parameters for the storage devices. The second DHCP server may be configured to process DHCP messages and retrieve configuration parameters for the storage devices from the configuration datastore. In certain embodiments, each storage initiator communicates with the DHCP servers, receives the configuration parameters such as iSCSI parameters, and provides the configuration parameters to one or more storage devices.

    摘要: Apparatuses and methods to request multicast membership information in a distributed switch are provided. A particular method may include requesting multicast membership information of a group identified by a multicast destination address in a distributed switch. The distributed switch may include a plurality of distributed switch elements with a plurality of switch forwarding units. The method may generate a miss event indicating that the multicast destination address is unregistered in a switch forwarding unit of a distributed switch element and there is a need for the multicast membership information. The method may also request the multicast membership information of the multicast destination address in response to the miss event. The method may further initiate a query for the multicast membership information of the multicast destination address in response to the request.

    摘要: Techniques are provided for multicast miss notification for a distributed network switch. In one embodiment, a bridge element in the distributed network switch receives a frame destined for a multicast group on a network. If a local multicast forwarding table of the bridge element does not include any forwarding entry for the multicast group, a forwarding entry is selected from the local multicast forwarding table as a candidate for being replaced. An indication of the candidate is sent to a management controller in the distributed network switch.

    摘要: The different switch modules making up a distributed virtual switch may route configuration commands for hardware resources to different modules within the distributed switch using a distribution and routing layer. At least one of the switch modules maintains a routing table that defines which switch modules are responsible for which hardware resources. The switch module uses the routing tables to forward the commands on the distribution and routing layer to the responsible switch module which then ensures that the relevant hardware resources are configured.

    摘要: A method and apparatus are provided for implementing service requests from a common database in a multiple dynamic host configuration protocol (DHCP) server environment. A DHCP authorization cache is provided to implement synchronized access for the multiple DHCP servers to the common database. The DHCP authorization cache includes a plurality of elements, each element for storing a plurality of entries including a client identifier, an ISCSI DHCP router pointer, an ISCSI DHCP router pointer alternate, and a timestamp and the DHCP authorization cache includes an entry pointer initially set to zero.
