Abstract: Systems and methods for dynamically assigning membership in a data partition to an end-port of a requesting host channel adapter. An exemplary embodiment can provide a subnet manager configured to operate within a subnet of a network fabric. The subnet can include a plurality of nodes, and the plurality of nodes can include at least one switch and a plurality of end-nodes, where the subnet manager executes on one of the plurality of nodes. A host channel adapter of a node in the subnet can request membership for an end-port of the host channel adapter. In response to the request, the subnet manager can request data from the data store to confirm that the end-port is a member of an admin partition and that the admin partition is associated with the data partition in which membership was requested.

Abstract: Systems and methods for defining virtual machine fabric profiles of virtual machines. An exemplary embodiment can provide a virtual machine identifier, a virtual host channel adapter instance ID, and a virtual globally unique identifier. The virtual machine identifier, virtual host channel adapter instance ID, and virtual globally unique identifier can be mapped to each other so that the virtual host channel adapter instance ID, and virtual globally unique identifier can be retrieved through access to the virtual machine identifier. Further, a relationship can be created between a P_Key that defines an admin partition and the virtual globally unique identifier, where the relationship between the P_Key and the virtual globally unique identifier defines the virtual globally unique identifier as a member of the admin partition defined by the P_Key.

Abstract: Systems and methods of reserving a specific queue pair number for proprietary management traffic in a subnet of a high performance computing environment. An exemplary embodiment can provide a host channel adapter (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 configurable attribute stored in the memory of the HCA. A communication including a number value, can be received by the subnet management agent from a subnet manager of the subnet. The value of the configurable attribute can be set equal to the value of the received number. A QP number that corresponds to the set number value of the configurable attribute can then be reserved for sending and receiving proprietary network management traffic.

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 for initiating a forced migration of a virtual machine. An exemplary embodiment can provide a subnet manager (SM) and an active virtual machine registration cache, where the subnet manager can access the active virtual machine registration cache. The SM can record a first virtual machine incarnation number in the active virtual machine registration cache, where the virtual machine incarnation number is associated with an active virtual machine (VM). Upon receiving a request to register the active VM on a different host, the SM can evaluate a second virtual machine incarnation number with the first virtual machine incarnation number to determine the legality of the request. In accordance with an embodiment, if the second virtual machine incarnation number is evaluated as greater than the first virtual machine incarnation number, the SM determines the request is legal.

Abstract: Systems and methods for application of virtual host channel adapter configuration policies. An exemplary embodiment can provide a host channel adapter (HCA) with a control circuit and a memory, and at least one port operative to connect the HCA to a network fabric. A software driver of the HCA can provide a control API that exposes functionality to hyper-privileged software executing on the host. The hyper privileged software, through the control API, can request registration of a virtual HCA (vHCA) with a virtual function of the HCA. The HCA can forward the registration request to a subnet manger, which can retrieve configuration policies from a cache and return the policies to the HCA for implementation with the virtual function of the HCA.

Abstract: Systems and methods for using a virtual machine fabric profiles to reduce virtual machine downtime during migration. An exemplary embodiment can provide a subnet manager (SM) and a virtual machine fabric profile that is accessible by the subnet manager, and where the virtual machine fabric profile includes a virtual host channel adapter (vHCA) configuration. The SM can receive a request to preregister the vHCA with a first physical host channel adapter (HCA) while the vHCA is already actively registered with a second physical HCA. The subnet manager can send the vHCA configuration to the first physical HCA for preregistration. After preregistration, the virtual link between the vHCA and a vSwitch of the first physical HCA can be left unestablished, until the SM determines that a virtual link between the vHCA and a vSwitch on the second physical HCA has been disconnected.

Abstract: System and method for correlating fabric-level group membership with subnet-level partition membership in a high performance computing environment. An exemplary embodiment can provide an admin partition in a subnet of a network environment, associated with a resource domain at the fabric level of the network environment. The admin partition can be defined by a P_Key that is stored in a fabric-level database. Each fabric resource is identified by an identifier that is stored in the fabric-level database. When fabric resources are added as members to the resource domain, a relationship is created between the P_Key and the identifier of the fabric resource, where the relationship defines the resource as a member of the admin partition. Access rights can be granted based on the relationship.
