An architecture and methodology for designing, deploying, and managing a distributed application onto a distributed computing system is described.

Architecture for distributed computing system and automated design, deployment, and management of distributed applications

The disclosed embodiments include system and method for routing communications over a communications network. In one embodiment, a determination is made as to whether to establish a communication along a communication path based on network performance information. The disclosed embodiments provide several alternatives for establishing the communication and improving communications along the communication path in response to a determination that at least one network node along the communication path is impaired or congested.

System and method for routing data on a packet network

Provided are a method, system, and program for managing multiple resources in a system at a service level, including at least one host, network, and a storage space comprised of at least one storage system that each host is capable of accessing over the network. A plurality of service level parameters are measured and monitored indicating a state of the resources in the system. A determination is made of values for the service level parameters and whether the service level parameter values satisfy predetermined service level thresholds. Indication is made as to whether the service level parameter values satisfy the predetermined service thresholds. A determination is made of a modification to one or more resource deployments or configurations if the value for the service level parameter for the resource does not satisfy the predetermined service level thresholds.

Method, system, and program for determining a modification of a system resource configuration

In a first exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, direct a system to perform actions that include: accumulating host status information at multiple hosts; and sending the accumulated host status information from the multiple hosts In a second exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, direct a system to perform actions that include: receiving host status information from multiple hosts; and making load balancing decisions responsive to the received host status information In a third exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, direct a system to perform actions that include: determining health and load information on a per application basis; and selecting an application from among multiple applications responsive to the health and load information

Network load balancing with host status information

In an exemplary method implementation, a method includes: receiving a packet requesting a new connection at a forwarding component; sending the packet from the forwarding component to a classifying component; selecting, by the classifying component, a route for the new connection; and plumbing, by the classifying component, the route for the new connection by causing a new entry to be added in a local routing table of the forwarding component. In an exemplary media implementation, one or more processor-accessible media include processor-executable instructions that, when executed, enable a system to perform actions including: receiving a first packet for a connection at first forwarding functionality; plumbing a route for the connection at the first forwarding functionality; receiving a second packet for the connection at second forwarding functionality; and plumbing the route for the connection at the second forwarding functionality using a distributed session tracking table.

Network load balancing with traffic routing

A method and apparatus for managing the availability and assignment of data in a storage system that is coupled to a network. A user interface is provided that executes on a host processor that is coupled to the storage system over the network. The user interface communicates with a configuration database in the storage system to identify host processors that are logged into the storage system over the network, to identify storage volumes on the storage system, to identify whether access to a particular storage volume on the storage system is permitted from a particular host processor, and to identify a network path by which host processors are logged into the storage system over the network. In one embodiment, a graphical user interface is provided that can be used to graphically represent host processors, host bus adapters, storage systems, and storage system adapters and storage volumes on the storage system. The graphical representation provided by the graphical user interface permits a user to graphically view a topology of the network at varying levels of detail, selectable by the user. The graphical user interface also permits a user to allow or deny access to storage systems or a particular storage volume on storage system from one or more of the host processors, host bus adapters, etc., by selecting and manipulating graphical representations thereof. In another embodiment, a command line user interface is provided with similar functionality.

Method and apparatus for identifying network devices on a storage network

A data management technique for managing accesses to data at a shared storage system includes a filter at the storage system. The filter is coupled to a configuration table, which identifies which of a number of coupled host processors have accesses to each of the resources at the device. During operation, requests received from the host devices are filtered by the filter, and only those requests to resources that the individual host devices have privilege to access are serviced. Advantageously, data security is further enhanced by authenticating each of the requests received by the storage system to verify that the host processor that is represented as forwarding the request is the indicated host processor. In addition, transfers of data between the storage system and the host processor may be validated to ensure that data was not corrupted during the data transfer.
