摘要： Techniques are provided to move the services performed on one device to another device in a cloud computing system for a variety of reasons including failure, maintenance or upgrade of the device. A notification is received that services performed by an impacted device in a domain of a plurality of hierarchical domains need to be moved. A determination is made as to whether there are replacement resources available in the domain to perform the services, and if so, the replacement resources are automatically rendered to perform the services. The process continues to higher level domains that have a view into the capabilities of subordinate domains in order to determine where to move the services within the cloud computing system.

摘要： Techniques are provided herein for defragmenting resources within a cloud computing system. The cloud computing system includes a plurality of servers deployed in a plurality of respective racks, wherein the respective racks are deployed in a pod of a data center. An element of the cloud computing system determines for each server in a given rack of servers a number of free resource slots available thereon and a number of resource slots in an idle state, and then further determines whether the number of free resource slots on a first server in the plurality of servers is greater than a predetermined threshold. When the number of free resource slots in the first server is greater than the predetermined threshold, a second server in the plurality of servers is identified with sufficient resource slots thereon to accommodate the number of resource slots in the idle state on the first server, and the resource slots in the idle state on the first server are caused to be migrated to the second server.

摘要： 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.

摘要： Techniques are provided for a switch to assign proxy FCIDs to endpoint device so that the endpoint devices may achieve FCID mobility by retaining their originally assigned FCIDs. At a switch in a network, e.g., a Virtual Storage Area Network (VSAN), a fabric login request is received from a first endpoint device that is associated with a first FC identifier (FCID) that was previously assigned to the first endpoint device by another switch in the VSAN. The fabric login request is responded to with the first FCID. The first endpoint device is assigned a second FCID associated with a domain of the switch where the endpoint device is directly attached to, and the second FCID is used as a proxy FCID within the VSAN for the first endpoint device. A frame is received from the first endpoint device with a source FCID comprising the first FCID and a destination FCID comprising an FCID for a second endpoint device. The source FCID in the frame is overwritten with the second FCID. The frame is forwarded to the second endpoint device.

摘要： Disclosed are methods and apparatus for redirecting fiber channel data that is transmitted between a first and a second node, such as a host and target, in a storage area network (SAN) to an intelligent node that facilitates implementation of a service on such redirected data. Such redirection is provided transparently with respect to the first and second nodes without significantly reconfiguring the existing infrastructure of the first and second nodes. In a specific Fiber Channel implementation, the redirection is accomplished without rewiring any of the nodes in the network fabric or reconfiguring zones or virtual storage area networks (VSANs). In general, such redirection is accomplished by rewriting the data as it traverses on a path between the first and second node towards an original destination (e.g., the first or second node) so that the data is redirected to an intelligent node. The intelligent node then facilitates implementation of a service on such redirected data and then forwards the serviced data back to its original destination. In one example, setup of this redirection function is accomplished simply by making a request to a network device (e.g., a host and/or target switch) in the first and second node's communication path, where the request identifies the first node, the second node, and the intelligent node.

摘要： 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.

摘要： In a node of a data communication system with a number of nodes, in which data communication system isochronous and asynchronous data is exchanged through a serial data bus structure, multiple link layer interface circuits are coupled to a single physical layer interface circuit. The physical layer interface circuit has an external port through which the physical layer interface circuit is connected to the serial bus structure. The physical layer interface circuit is coupled to the link layer interface circuits through bi-directional switches. A logic circuit controls the bi-directional switches and, in dependence of configuration information stored in configuration registers of the link layer interface circuits and its own programming, the logic circuit controls routing of isochronous and asynchronous data streams from the link layer interface circuits to the physical layer interface circuit, and from the physical layer interface circuit to the link layer interface circuits.
