  • Patent number: 8145785
    Abstract: Real time provisioning and management of fabric-backplane enterprise servers includes monitoring system status and configuration, displaying monitoring results, accepting user commands, and providing hardware and software management and configuration commands to the system. In one embodiment, an event is generated when a pluggable module is inserted into the system. In response to the event, the availability of the pluggable module is displayed to a system operator, and the operator enters a command to provision a server that includes the pluggable module. The server provisioning command is processed, resulting in a hardware configuration command being issued to the system, and an event indicating a status associated with processing the command is returned. The recognition of the inserted module, the display to the operator, and the processing of the server provisioning command occur in real time.

  • Patent number: 7990994
    Abstract: Storage gateway provisioning, configuration, and management functions provide mechanisms to specify and manage parameters and operations associated with storage gateways. The parameters may include any combination of VLAN topology, zoning behavior, LUN masking, bandwidth, and priority. The parameters may also include path information describing initiator to target associations, enabling load-balancing aggregations and multipathing redundancy. Parameters may be specified at relatively low-levels, describing specific HW elements, or may be specified at relatively high-levels, describing desired bandwidth and redundancy requirements, with SW determining low-level HW assignments. Configuration and management functions enable dynamic modification of storage gateway parameters (such as bandwidth between selected initiator and target pairs). Management functions also enable dynamic switchover from a primary path to a secondary path with respect to a storage device.

  • Patent number: 7872989
    Abstract: An optimized spanning tree protocol (OSTP) minimizes latency and provides high throughput in a full-mesh portion of a network, and is compatible with external networks where a standard spanning tree protocol is used. The OSTP enables traffic traversing the full-mesh portion to take a shortest path from source to destination through use of full-mesh connectivity. In some embodiments, a cluster includes a plurality of servers connected in a full mesh, and the OSTP is used on internal ports of the servers. In some embodiments, the OSTP is configured on a per-VLAN basis. In some embodiments, the servers exchange special messages enabling determination of full-mesh connectivity. In further embodiments, sending of the special messages is suppressed on certain port types, such as external ports. In some embodiments, determination of the full-mesh connectivity disables use of a standard spanning tree protocol and/or enables use of OSTP on the full-mesh portion.

  • Patent number: 7873693
    Abstract: Multi-chassis fabric-backplane enterprise servers include a plurality of chassis managed collectively to form one or more provisioned servers. A central client coordinates gathering of provisioning and management information from the chassis, and arranges for distribution of control information to the chassis. One of the chassis may perform as a host or proxy with respect to information and control communication between the client and the chassis. Server provisioning and management information and commands move throughout the chassis via an Open Shortest Path First (OSPF) protocol. Alternatively, the client may establish individual communication with a subset of the chassis, and directly communicate with chassis in the subset. Server provisioning and management information includes events generated when module status changes, such as when a module is inserted and becomes available, and when a module fails and is no longer available.
