20120072562 | PERFORMING PARTIAL SUBNET INITIALIZATION IN A MIDDLEWARE MACHINE ENVIRONMENT - A system and method can perform subnet initialization in a middleware machine environment. In accordance with one embodiment, a plurality of management nodes in the middleware machine environment can be interconnected so that a plurality of subnet managers that are associated with the plurality of management nodes can communicate with each other using an in-band communication protocol. The plurality of subnet managers can negotiate and elect a master subnet manager, which operates to configure and manage the middleware machine environment. The master subnet manager can replicate one or more subnet initialization policies to other subnet managers in the middleware machine environment using the in-band communication protocol. The master subnet manager can then set up a plurality of client nodes in the middleware machine environment based on the one or more subnet initialization policies. | 03-22-2012 |

The transactional interface allows for updating the one or more policies using a policy update transaction. The policy daemon co-located with the master subnet manager operates to replicate the policy update transaction to one or more policy daemons co-located with the subnet managers that are master candidates associated with the master subnet manager, before committing the policy update transaction. Additionally, when the master subnet manager fails, the subnet managers operate to negotiate with each other and elect a new master subnet manager. | 03-29-2012 |
20120079580 | SYSTEM AND METHOD FOR FACILITATING PROTECTION AGAINST RUN-AWAY SUBNET MANAGER INSTANCES IN A MIDDLEWARE MACHINE ENVIRONMENT - 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 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. | 03-29-2012 |

Each partition in the subnet can be associated with a separate internal ID space, and a single physical HCA instance is prevented from being shared by different tenants that use a same internal ID value in different partitions. | 12-06-2012 |
20120311124 | SYSTEM AND METHOD FOR SUPPORTING SUBNET MANAGER (SM) LEVEL ROBUST HANDLING OF UNKOWN MANAGEMENT KEY IN AN INFINIBAND (IB) NETWORK - A system and method can support subnet manager (SM) level robust handling of an incoming unknown management key in an InfiniBand (IB) network. A local SM in a fabric is adaptive to receive an incoming subnet management packet (SMP) from a remote SM, wherein the SMP contains a first management key. Furthermore, the local SM operates to check whether the first management key is consistent with a configuration associated with the local SM, and can silently drop the incoming SMP if the first management key is not consistent with the local SM configuration. | 12-06-2012 |
