    Abstract: Systems and methods for host-side configuration of a host channel adapter (HCA). An exemplary embodiment can provide a HCA, including a control circuit with a processor and a memory, and at least one port operative to connect the HCA to a network fabric. Additionally, the HCA can include a subnet management agent (SMA) that executes on the HCA, and a software driver for the HCA that includes a control application programming interface (API) that exposes functionality to hyper-privileged software executing on a host. The hyper-privileged software can set, through the control API, configurable variables stored in the memory of the HCA. Based on the value of the set variables, the HCA can operate in one of a legacy mode or one or more other modes.

    Abstract: Systems and methods are provided for supporting scalable multi-homed routing for virtual switch based host channel adapter (HCA) virtualization in a subnet. An exemplary method can provide one or more switches, a plurality of host channel adapters, a plurality of hypervisors, and a plurality of virtual machines. The method can arrange the plurality of host channel adapters with one or more of a virtual switch with prepopulated local identifiers (LIDs) architecture or a virtual switch with dynamic LID assignment architecture. The method can further perform a multi-homed routing for the subnet, wherein at least one of the plurality of host channel adapters comprises two virtual switches, wherein the two virtual switches are treated as endpoints of the subnet, and wherein the multi-homed routing for the subnet ensures that each the two virtual switches are routed through independent paths.

    Abstract: 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.

    Abstract: A system and method can implement highly available Internet Protocol (IP) based communication across multiple independent communication paths. The system can have different IP addresses associated with different interfaces and communication paths and can implement communication fail-over as part of the communication layers above the IP layer, e.g. at the application level. The system can provide a balance between an average fail-over time and implementation complexity, and can achieve simplicity and robustness while providing high communication performance.

    Abstract: A system and method can support discovering and routing in a fabric with a plurality of switches. The system allows one or more switches in the fabric to be tagged with a switch role. Then, a subnet manager in the fabric detect the switch role that is associated with the one or more switches. Furthermore, a routing algorithm can be applied on the fabric based on the detected switch role associated with the one or more switches.
