Abstract: Systems and methods for supporting heterogeneous and asymmetric dual rail fabric configurations in a high performance computing environment. A method can provide, comprising at one or more computers each including one or more microprocessors, a plurality hosts, each of the plurality of hosts comprising at least one dual port adapter, a private fabric, the private fabric comprising two or more switches, and a public fabric, the public fabric comprising a cloud fabric. A workload can be provisioned at a host of the plurality of hosts. A placement policy can be assigned to the provisioned workload. Then, network traffic between peer nodes of the provisioned workload can be assigned to one or more of the private fabric and the public fabric in accordance with the placement policy.

Abstract: Systems and methods for supporting redundant independent networks in a high performance computing environment. A method can provide, at a computer comprising one or more microprocessors, one or more switches, one or more racks, each of the one or more racks comprising a set of the one or more switches, each set of the one or more switches comprising at least a leaf switch, a plurality of host channel adapters, at least one of the plurality of host channel adapters comprising a firmware and a processor, and a plurality of hosts. The method can provision two or more rails, the two or more rails providing redundant connectivity between the plurality of hosts. The method can isolate data traffic between the plurality of hosts to a rail of the two or more rails.

Abstract: A system and method can support subnet management in a network environment. One or more inactivated switches can be included in a subnet, wherein each of the inactivated switches is associated with an empty set of known secret keys. A subnet manager (SM) in a dry-run mode can perform one or more dry-run operations on the one or more inactivated switches, before activating the one or more inactivated switches.

Abstract: A system and method can support controlled re-routing in an InfiniBand (IB) fabric. The fabric is associated with a subnet manager that can detect a connectivity change in the fabric, and re-rout the fabric accordingly. The subnet manager can ensure that only accredited components and connectivity are utilized in the re-routing, and represent the connectivity that is not accredited within a local subnet or sub-subnet. The subnet manager can further maintain a node record or fabric configuration for evaluating the detected connectivity change in the fabric.
