20120311123 | SYSTEM AND METHOD FOR SUPPORTING CONSISTENT HANDLING OF INTERNAL ID SPACES FOR DIFFERENT PARTITIONS IN AN INFINIBAND (IB) NETWORK - 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. | 12-06-2012 |
20120311332 | SYSTEM AND METHOD FOR PROVIDING SECURE SUBNET MANAGEMENT AGENT (SMA) IN AN INFINIBAND (IB) NETWORK - 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. | 12-06-2012 |
20120311670 | SYSTEM AND METHOD FOR PROVIDING SOURCE ID SPOOF PROTECTION IN AN INFINIBAND (IB) NETWORK - 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. | 12-06-2012 |
20130019303 | SYSTEM AND METHOD FOR PROVIDING SWITCH BASED SUBNET MANAGEMENT PACKET (SMP) TRAFFIC PROTECTION IN A MIDDLEWARE MACHINE ENVIRONMENT - 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. | 01-17-2013 |
20130124910 | SYSTEM AND METHOD FOR SIGNALING DYNAMIC RECONFIGURATION EVENTS IN A MIDDLEWARE MACHINE ENVIRONMENT - 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. | 05-16-2013 |

20150063355 | SYSTEM AND METHOD FOR SUPPORTING DATA SERVICE ADDRESSING IN AN ENGINEERED SYSTEM FOR MIDDLEWARE AND APPLICATION EXECUTION - 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. | 03-05-2015 |
20150063356 | SYSTEM AND METHOD FOR SUPPORTING HOST CHANNEL ADAPTER (HCA) FILTERING IN AN ENGINEERED SYSTEM FOR MIDDLEWARE AND APPLICATION EXECUTION - 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. | 03-05-2015 |
20150067020 | SYSTEM AND METHOD FOR PROVIDING A DATA SERVICE IN AN ENGINEERED SYSTEM FOR MIDDLEWARE AND APPLICATION EXECUTION - 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. | 03-05-2015 |
20150067191 | SYSTEM AND METHOD FOR CONTROLLING A DATA FLOW IN AN ENGINEERED SYSTEM FOR MIDDLEWARE AND APPLICATION EXECUTION - 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. | 03-05-2015 |
