摘要： Systems and methods for supporting SMA level abstractions at router ports for enablement of data traffic in a high performance computing environment. In accordance with an embodiment, a subnet manager in a local subnet is responsible for enabling data traffic between subnets in a high performance computing environment. The SM can configure and set a data attribute at a switch port configured as a router port such that incoming data packets can be checked against the attribute to determine whether the data packet's destination is allowed or disallowed to receive inter-subnet data traffic.

摘要： System and method representing PMA attributes as SMA attributes in a high performance computing environment. In general legacy systems, performance metrics, as collected by a performance management agent, can only be collected via the use of general data packets traversing a subnet. In accordance with an embodiment, by configuring a SMA attribute to comprise the same performance metrics as collected by a PMA, a subnet manager, or another management component, can access the performance metrics in-band via the use of a subnet management packet.

摘要： A system and method can support a middleware machine environment that includes a set of subnet manager instances, which reside on one or more nodes in the middleware machine environment and cooperate to provide a highly available subnet manager service within a subnet, wherein each said subnet manager instance is associated with a different private secure key. The subnet manager instances can negotiate with each other and elect a master subnet manager responsible for configuring and managing the middleware machine environment using the private secure key associated with the master subnet manager. The subnet can be reconfigured to be associated with a different private secure key, when a new subnet manager instance is elected as the master subnet manager. An old master subnet manager can be automatically prevented from resuming normal operations as the master subnet manager, in order to avoid undesired consequence such as a “split brain” scenario.

摘要： A system and method for supporting subnet management in a network environment is described. The system and method can be used in an engineered system for middleware and application execution, or a middleware machine environment. The system can associate a subnet administrator (SA) in a subnet with a plurality of SA proxies, each of which can receive plurality of requests from one or more client nodes. The SA can handle the requests, which are forwarded from the SA proxies. Additionally, each client node can be assigned a dedicated queue pair (QP) number, so that there is no need for always sending an initial request to a pre-defined well-known QP number.

摘要： A system and method can ensure Internet Protocol (IP) address and node name consistency when performing remote transactions via multiple un-related IP addresses for the same remote peer. The system can ensure that all cooperating peer nodes are in full agreement of the names and IP addresses at any point in time. In particular, when network configurations can be updated dynamically, the system can ensure that such updates do not lead to inconsistent or failed transactions because a peer node has a stale view of what addresses to use. Furthermore, the peer node that initiates the transaction can verify that all the other peer nodes have exactly the same view of the overall system configuration, in order to ensure that each distributed transaction is carried out using consistent address information.
