Abstract: Methods and apparatus are provided for improving the configuration, management, and distribution of quality of service information in a fibre channel fabric using zoning mechanisms. Configuration of Quality of Service (QoS) information is made easy by using zones as a classifier for flows. QoS information is included in zone objects, thereby using the existing zone distribution mechanism to distribute QoS information. Devices not part of any zones are placed automatically in the default zone with a default QoS priority level. QoS information for a particular packet is available as soon as the zoning information is obtained.

Abstract: 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 Fibre 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 Fibre Channel domain from the Fibre Channel fabric.

Abstract: A Fibre Channel Switch which enables end devices in different Fabrics to communicate with one another while retaining their unique Fibre Channel Domain_IDs. The Switch is coupled to a first fabric having a first set of end devices and a second fabric having a second set of end devices. The Switch is configured to enable communication by the first set of end devices associated with the first fabric with the second set of end devices associated with the second set of end devices using the unique Domain_IDs of each of the first set and the second set of end devices. In one embodiment of the invention, the first and second fabrics are first and second Virtual Storage Array Networks (VSANs) respectively. In an alternative embodiment, the first fabric and the second fabric are separate physical fabrics.

Abstract: According to the present invention, methods and apparatus are provided to allow for distribution of fiber channel messages. Messages associated with a variety of applications can be distributed within a single logical fabric to physical connected but logically disconnected fabrics. Interconnecting switches forward messages to neighboring fabrics and aggregate responses before replying to a first fabric.

Abstract: A granular castable refractory composition is provided which has excellent insulating properties as well as high strength and resistance to oxidation, corrosion or erosion. The refractory insulating composition can be easily transported using a pump, and avoids the potential hazards associated with asbestos and ceramic fibers. The refractory insulating composition is prepared by mixing a low density expanded granular refractory insulating material having a density of 7-50 lb/ft.sup.3 with a conventional high density refractory material having a density of at least 150 lb/ft.sup.3 to form a dry component, and by mixing the dry component with aqueous colloidal silica to provide excellent flow properties for pumping and, ultimately, excellent binding properties.

Abstract: Techniques are provided for sending from a client in a first network device a first session-initiate message to a second network device that is configured to provide network layer, data link layer, or associated convergence layer based service connection information in order for the second network device to accept or reject a network layer, data link layer, or associated convergence layer based service connection with the first network device. The first session-initiate message is based on a messaging and presence protocol. A session-accept message is received at the client in the first network device that is configured to accept the service connection and provide a network layer, data link layer, or associated convergence layer based service connection information in order for the first network device to establish the service connection with the second network device. The session-accept message is based on the messaging and presence protocol. In response to receiving the session-accept message, the service connection is established.
