Abstract: A hybrid reconfiguration scheme can allow for fast partial network reconfiguration with different routing algorithms of choice in different subparts of the network. Partial reconfigurations can be orders of magnitude faster than the initial full configuration, thus making it possible to consider performance-driven reconfigurations in lossless networks.

Abstract: Systems and methods for providing explicit multicast local identifier assignment for per-partition default multicast local identifiers defined as subnet manager policy input in a high performance computing environment. In accordance with an embodiment, an explicit multicast local identifier (MLID) assignment policy can be provided (as, e.g., administrative input) that explicitly defines which MLIDs will be used for which partitions in a subnet. Further, an MLID assignment policy can also define which dedicated MLIDs will be associated with given multicast group idnetifiers (for example, partition independent MLIDs). By employing such an MLID assignment policy, a new or restarted master subnet manger can observe and verify the MLIDs used for existing partitions, instead of generating new MGID to MLID mappings. In this way, changes in MLID associations for any corresponding MGID can be avoided as a result of master SM restarts or failovers, or any subnet-merge operations.

Abstract: Systems and methods for providing dual multicast local identifiers (MLIDs) per multicast group to facilitate both full and limited partition members in a high performance computing environment. In accordance with an embodiment, in order to avoid the need for the above special handling of P_Key access violations, as well as to ensure complete isolation between limited partition members in terms of multicast traffic, two MLIDs can be allocated to a single MCG, in accordance with an embodiment. A first MLID can be allocated and used by end-ports for sending from full partition members to both full and limited partition members. Additionally, a second MLID can be allocated and used by end-ports for sending from limited partition members to full partition members. Using this scheme, a limited partition member can avoid sending multicast packets to other limited partition members in the MCG.

Abstract: A system and method can support virtual machine live migration in a network. A virtual switch can be associated with a plurality of virtual functions (VFs), and wherein each said virtual function (VF) is associated with a separate virtual interface (VI) space. At least one virtual machine that is attached with a said virtual function (VF) can be associated with a virtual interface (VI), e.g. a queue pair (QP) in an Infiniband (IB) architecture. Furthermore, said at least one virtual machine operates to perform a live migration from a first host to a second host with said virtual function (VF) attached.

Abstract: An integrated firewall provides security in a multi-tenant environment having a connection-based switched fabric directly connecting database servers which provide a plurality of database services with application servers hosting database service consumers each having a different database service consumer identity. The firewall functionality integrated into each database server provides access control by discarding communication packets which do not include a database service consumer identity and using the database service consumer identity in combination with an access control list to control access from the database service consumers to the database services. The access control includes address resolution access control, connection establishment access control, and data exchange access control based on said access control list. The integrated firewall enables direct connection of database servers and application servers via an InfiniBand network providing without requiring a separate intermediary firewall appliance or security node.

Abstract: System and method for supporting flexible forwarding domain boundaries in a high performance computing environment. In accordance with an embodiment, flexible forwarding domain boundaries can be supported by dividing/partitioning a physical switch into two or more logical switches, where each switch is logically in a different domain, and allowing a fabric to be decomposed into independent subnets with one two or more physical end ports at the physical switch. By doing so, the same hierarchical forwarding structure and management structure between subnets can be provided as when complete physical switches are used as building blocks.

Abstract: System and method for supporting multiple concurrent SL to VL mappings in a high performance computing environment. In accordance with an embodiment, systems and methods can provide for two or more SL to VL mappings per ingress switch port in a network switched fabric. By allowing for multiple such mappings, greater virtual lane independence can be achieved while continuing to achieve quality of service guarantees.

Abstract: A system and method can support partition-aware routing in a multi-tenant cluster environment. An exemplary method can support one or more tenants within the multi-tenant cluster environment. The method can associate each of the one or more tenants with a partition of a plurality of partitions. The method can then associate each of the plurality of partitions with one or more nodes of a plurality of nodes, each of the plurality of nodes being associated with a leaf switch of a plurality of switches, the plurality of switches comprising a plurality of leaf switches and a plurality of root switches. Finally, the method can generate one or more linear forwarding tables, the one or more linear forwarding tables providing isolation between the plurality of partitions, wherein each of the plurality of nodes is associated with a partitioning order.
