Systems and methods for using InfiniBand routing algorithms for Ethernet fabrics in a high performance computing environment. The method can provide, at a computer comprising one or more microprocessors, a plurality of switches, a plurality of hosts, a topology provider (TP) module, a routing engine (RE) module, and a switch initializer (SI) module. The method can perform a discovery sweep, by the TP, of the plurality of hosts and the plurality of switches and assigns an address to each of the plurality of hosts and the plurality of switches. The method can calculate, by the routing engine, a routing map, based upon a routing scheme, for the plurality of hosts and the plurality of switches, the routing map comprising a plurality of forwarding tables. The method can configure, each of the plurality of switches with a forwarding table of the plurality of forwarding tables calculated by the routing engine.

An exemplary method can provide, at a computer comprising one or more microprocessors, a plurality of switches, a plurality of host channel adapters, and a plurality of hosts. The method can provide, at two rails, redundant connectivity between the plurality of hosts, wherein each rail comprises a set of the plurality of switches. The method can detect a disruption i connectivity between two hosts of the plurality of hosts. The method can re-establish communication between the two hosts of the plurality of hosts via unicast packets on an inter-rail link, the inter-rail link being provided between the two rails.

A system and method can support consistent handling of internal ID space for different partitions in an InfiniBand (IB) network. A plurality of partitions can be provided for a subnet with a plurality of hosts, wherein each partition of the subnet includes one or more hosts and each host can be associated with one or more physical HCA instances. 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.

A system and method can provide a data service in a network environment. The system can provide a data service component on a node in the network environment, wherein the network environment includes a plurality of nodes interconnected via a network fabric. Furthermore, the system can use a native packet forwarding mechanism to direct a data flow in the network fabric to said data service component on the node. Then, the system can use said data service component to process one or more data packets in the data flow in the network fabric.

A system and method can provide source ID spoof protection in an InfiniBand (IB) fabric. The IB fabric can support a plurality of tenants in a subnet that connects a plurality of physical servers, wherein the plurality of tenants are associated with different partitions in the subnet. Then, the plurality of tenants can use at least one shared service, and the IB fabric can be configured to determine what ID values are legal for different physical servers and different partitions.

A system and method can provide a data service in a network environment. A subnet administrator can receive a path record resolution request from a source node, wherein the source node uses the path record resolution request to obtain an address of a destination node. Furthermore, the subnet administrator can provide an address of an intermediate node to the source node, wherein the intermediate node provides the data service. Then, the source node can send one or more data packets in a data flow to the intermediate node based on the address of the intermediate node.

A system and method can support data service address resolution in a network environment. An intermediate node can receive an incoming data packet from a source node, wherein the incoming data packet targets a destination node, and wherein the incoming data packet includes a global identifier for the destination node and a local identifier for the intermediate node. Furthermore, the intermediate node can obtain local addressing information for the destination node based on the global identifier for the destination node. Then, the intermediate node can send an outgoing data packet to the destination node based on the obtained local addressing information for the destination node.

A system and method can provide a data service in a network environment. The network environment can include a node, which supports a data service component that can provide a data service. Additionally, a filter can be provided on a networking device, such as a host channel adaptor (HCA) that is associated with the node. The networking device operates to use the filter to identify one or more packets targeting the data service component without protocol termination. Furthermore, the filter can forward said one or more packets to the data service component.

A system and method can provide switch based subnet management packet (SMP) traffic protection in a middleware machine environment. The middleware machine environment includes a network switch that operates to receive at least one SMP destined for a subnet management agent (SMA). The network switch can check whether the at least one SMP includes a correct management key, and prevent the at least one SMP from being forwarded to the destined SMA when at least one SMP does not include the correct management key. Furthermore, the network switch can specify a different management key for each external port and can enforce separate restrictions on ingress and egress SMP traffic at a particular external port.

A system and method can provide a secure subnet management agent (SMA) in an Infiniband (IB) network. The system can comprise a host channel adapter (HCA) associated with a host, wherein the HCA operates to implement a SMA in its embedded firmware. The HCA can prevent a host administrator or software with root access to the host from changing the embedded firmware on the HCA and modifying one or more states associated with the SMA without being endorsed by a site administrator. Additionally, the SMA is associated with a management key, and the host is not allowed to observe the management key without being endorsed by a site administrator.

A system and method can provide fault tolerance in a middleware machine environment. A subnet manager can determine whether there is a path record change when a fault occurs in the middleware machine environment. Furthermore, the subnet manager can signal a dynamic reconfiguration event to at least one host in the middleware machine environment. The at least one host can send a message to the subnet manager to query for a latest path record. Then, the subnet manager can provide a latest path record to the at least one host.

One embodiment of the invention provides a method of operating a switch in a communications network. The method includes storing a set of routings for each port in the switch. When a packet is received at a port in the switch, the set of routings corresponding to the port at which the packet was received is accessed. A port from which to forward the packet from the switch is determined in accordance with the set of routings. The packet is then duly forwarded over the network from the port as determined by the routings.

A fault zone definition mechanism groups components of an interconnect environment having a common point of dependence into a logical group defining a fault zone for the interconnect environment. The fault zone definition mechanism may be implemented in software, firmware or hardware, or a combination of two or more of software, firmware and hardware. A method for defining a fault zone is also disclosed.

One embodiment of the invention provides a method of handling an incoming packet at a node in a network. The method includes associating at least one source identifier with a link into the node. A packet is then received at the node over the link, and a source identifier is extracted from the received packet. The extracted source identifier is compared with the source identifier(s) associated with the link in order to authenticate the packet.
