| 20090132550 | IMPLEMENTING SERVICE REQUESTS FROM A COMMON DATABASE IN A MULTIPLE DHCP SERVER ENVIRONMENT - 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. | 05-21-2009 |
| 20090138608 | Automatic Multipath iSCSI Session Establishment Over an Arbitrary Network Topology - A method and apparatus for establishing multiple network sessions over an arbitrary network topology comprises receiving network configuration information describing an initiator system and a target controller. The initiator system contains one or more initiator ports. The target controller contains one or more target ports. Each target port is associated with one or more target nodes. A set of pre-defined rules is identified. The set of pre-defined rules governs the establishment of network sessions between the initiator ports and the target nodes through the target ports. One or more network sessions are established based on the set of pre-defined rules and the network configuration information. | 05-28-2009 |
| 20110258340 | Distributed Virtual Bridge Management - Systems and methods to forward data frames are described. A particular method may include receiving a data frame at a switch of a plurality of networked switches coupled to a plurality of server computers. The data frame may be forwarded from a controlling bridge coupled to the plurality of networked switches. The data frame may be determined to include management data, and an operating parameter of the switch may be modified. | 10-20-2011 |
| 20110258641 | Remote Adapter Configuration - Systems and methods to remotely configure adapters are described. A particular method may include generating a management frame at a controlling bridge. The management frame may include instructions to configure an operating parameter of the adapter. The management frame may be communicated to a bridge element of a plurality of interconnected bridge elements in communication with the controlling bridge. The bridge element may be coupled to the adapter, and the operating parameter of the adapter may be configured. | 10-20-2011 |
| 20110261815 | Multicasting Using a Multitiered Distributed Virtual Bridge Hierarchy - Systems and methods to multicast data frames are provided. A particular apparatus includes a plurality of computing nodes and a distributed virtual bridge. The distributed virtual bridge includes a plurality of bridge elements coupled to the plurality of computing nodes. The plurality of bridge elements are configured to forward a copy of a multicast data frame to the plurality of computing nodes using group member information associated with addresses of the plurality of server computers. A controlling bridge coupled to the plurality of bridge elements is configured to communicate the group member information to the plurality of bridge elements. | 10-27-2011 |
| 20110261826 | Forwarding Data Frames With a Distributed Fiber Channel Forwarder - Systems and methods to forward data frames are described. A particular method may include associating a fiber channel forwarder with a bridge element. The fiber channel forwarder may be one of a plurality of fiber channel forwarders coupled to the bridge element. A data frame received at the bridge element may be forwarded to the fiber channel forwarder. | 10-27-2011 |
| 20110261827 | Distributed Link Aggregation - Systems and methods to forward data frames are described. A particular method may include generating a plurality of management frames at a controlling bridge. The management frames may include routing information. The plurality of management frames may be communicated to a plurality of bridge elements coupled to a plurality of server computers. The plurality of bridge elements are each configured to selectively forward a plurality of data frames according to the routing information. | 10-27-2011 |
| 20110262134 | Hardware Accelerated Data Frame Forwarding - Systems and methods to forward data frames are described. A particular method may include evaluating header data of a data frame at a bridge element, where the header data includes address data that corresponds to a Fiber Channel Forwarder in communication with the bridge element. Based upon the evaluation, the header data of the data frame may be modified at the bridge element in such a manner that the data frame is not routed through the Fiber Channel Forwarder. | 10-27-2011 |
| 20110264610 | Address Data Learning and Registration Within a Distributed Virtual Bridge - Systems and methods to forward data frames are provided. A particular apparatus may include a plurality of server computers and a distributed virtual bridge. The distributed virtual bridge may include a plurality of bridge elements coupled to the plurality of server computers and configured to forward a data frame between the plurality of server computers. The plurality of bridge elements may further be configured to automatically learn address data associated with the data frame. A controlling bridge may be coupled to the plurality of bridge elements. The controlling bridge may include a global forwarding table that is automatically updated to include the address data and is accessible to the plurality of bridge elements. | 10-27-2011 |
