Abstract: Techniques are provided for monitoring the state or status of virtual data centers. In one embodiment, a method includes receiving state information representing the state of hardware devices supporting instantiations of virtual data centers operating within a physical data center. The state information is mapped to hardware devices supporting a selected instantiation of a virtual data center to identify state information for the selected instantiation of a virtual data center. An assessment is then made, based on the state information for the selected instantiation of a virtual data center, regarding a degree to which the selected instantiation of a virtual data center is operating in accordance with predetermined policy. A user is then notified of the assessment via, e.g., a color-coded dashboard representation of the selected instantiation of a virtual data center or a color-coded aspect of the selected instantiation of a virtual data center.

Abstract: A switch includes a processor, an ingress port having ingress port logic, and an egress port. It may also include a virtual network identifier rewrite component for rewriting a virtual network identifier in a data frame received the ingress port with a new virtual network identifier. Also included is a virtual network identifier rewrite rule set, where a rule may have one or more of the following: a received virtual network identifier, a source Fiber Channel identifier (FCID) address, an ingress port identifier, and a new virtual network identifier. The ingress port logic may insert a received virtual network identifier into the data frame received at the ingress port, where the virtual network identifier may correspond to the ingress port. The virtual network identifier rewrite component may assign the new virtual network identifier to the data frame according to a specific virtual network identifier rewrite rule.

Abstract: A first network device determines capabilities of resources in a section of a network that is accessible using the first network device. The first network device groups the resources into a resource cluster. The first network device advertises the resource cluster in the network, wherein each of a plurality of network devices advertise a resource cluster associated with sections of the network. A second network device receives a request for providing a service. The second network device groups the request into a plurality of request clusters. The second network device selects at least one resource cluster for providing the service based on information associated with the request clusters and the advertised resource clusters. The second network device allocates resources included in the at least one resource cluster for providing the service based on selecting the at least one resource cluster.

Abstract: Graph-based virtual data center requests are described. In some implementations, a method includes displaying a graph having graphical elements representing network resources. A user can select one of the graphical elements and provide input specifying requirements for a network resource corresponding to the selected graphical element. A virtual data center request can be generated based on the graph and the specified requirements. The virtual data center request can be transmitted to a data center device for processing. In some implementations, the virtual data center request can be an extensible markup language (XML) representation of the graph that includes the specified service requirements. In some implementations, a data center server can receive a graph-based virtual data center request and allocate data center resources based on the virtual data center request.

Abstract: Techniques are provided herein for distributed and hierarchical rendering and provisioning of cloud services. At a device in a cloud computing system comprising a plurality of hierarchical levels, a cloud service request is received for rendering and provisioning of a virtual data center. A determination is made as to which aspects of the cloud service request are to be satisfied by devices in a first hierarchical level and which aspects of the cloud service request are to be satisfied by devices in a second hierarchical level and in subsequent hierarchical levels. Rendering and provisioning commands are provided to one or more devices in the first hierarchical level that are selected to satisfy aspects of the cloud service request in the first hierarchical level. A subset cloud service request for aspects of the cloud service request that are to be satisfied by devices in the second hierarchical level is sent to a device in the second hierarchical level.

Abstract: Techniques are provided for receiving at a proxy device in a network, a login request from a source device, e.g., a Fiber Channel server in a server virtualization cluster, to access a destination device, a Fiber Channel storage array. The source device does not or need not have direct access to the destination device. A response to the login request is sent that is configured to appear to the source device that the response is from the destination device. The proxy device logs into the destination device on behalf of the source device to obtain access to the destination device. The proxy device receives first network traffic frames associated with a service flow between the source device and the destination device from the source device that are destined for the destination device. Information is overwritten within the first network traffic frames such that the first network traffic frames appear to originate from the proxy device when transmitted to the destination device. The first network traffic frames are transmitted from the proxy device to the destination device. Techniques are also provided herein for performing similar operations on frames sent from the destination device to the proxy device.

Abstract: Disclosed are apparatus and methods for facilitating communication between two devices from two different VSANs by propagating each device's presence from a first VSAN to the other device's different VSAN using a network address translation (NAT) mechanism. For instance, a first device, such as a host H1, from VSAN_A is allowed to access data from a second device, such as disk D1, of VSAN_B by propagating D1's presence into VSAN_A and H1's presence into VSAN_B. This awareness is accomplished by propagating an identifier for each device into the edge VSAN of the other device, as well as into any transit VSAN. So as to not duplicate identifiers in any one of the VSANs, a device's presence is propagated into a particular VSAN by assigning an unused domain for use by such device in the particular VSAN.

Abstract translation: 公开了通过使用网络地址转换（NAT）机制将每个设备的存在从第一VSAN传播到另一设备的不同VSAN来促进来自两个不同VSAN的两个设备之间的通信的装置和方法。 例如，允许来自VSAN_A的第一设备，例如主机H1，通过将D1的存在传播到VSAN_A和H1存在于VSAN_B中来访问来自VSAN_B的第二设备（例如盘D1）的数据。 该感知通过将每个设备的标识符传播到另一设备的边缘VSAN以及任何传输VSAN来实现。 为了不在任何一个VSAN中重复标识符，设备的存在通过分配一个未使用的域来传播到特定的VSAN中，供特定VSAN中的这种设备使用。
