| 20090034553 | SYSTEM AND ARTICLE OF MANUFACTURE FOR ENABLING COMMUNICATION BETWEEN NODES - Provided are a system and article of manufacture performed at a local node to communicate with a remote node. A first communication protocol is used to communicate with the remote node to establish a connection for a second communication protocol. Data structures are created to enable communication with the remote node to establish the connection with the remote node for the second communication protocol. An extension layer is invoked for the second communication protocol. The data structures are passed to the extension layer to use to communicate with the remote node using the second communication protocol. | 02-05-2009 |
| 20090064163 | Mechanisms for Creation/Deletion of Linear Block Address Table Entries for Direct I/O - The present invention provides mechanisms that enable application instances to pass block mode storage requests directly to a physical I/O adapter without run-time involvement from the local operating system or hypervisor. In one aspect of the present invention, a mechanism is provided for handling user space creation and deletion operations for creating and deleting allocations of linear block addresses of a physical storage device to application instances. For creation, it is determined if there are sufficient available resources for creation of the allocation. For deletion, it is determined if there are any I/O transactions active on the allocation before performing the deletion. Allocation may be performed only if there are sufficient available resources and deletion may be performed only if there are no active I/O transactions on the allocation being deleted. | 03-05-2009 |
| 20100217878 | METHOD, SYSTEM, AND PROGRAM FOR ENABLING COMMUNICATION BETWEEN NODES - Provided are a method, system, and program performed at a local node to communicate with a remote node. A first communication protocol is used to communicate with the remote node to establish a connection for a second communication protocol. Data structures are created to enable communication with the remote node to establish the connection with the remote node for the second communication protocol. An extension layer is invoked for the second communication protocol. The data structures are passed to the extension layer to use to communicate with the remote node using the second communication protocol. | 08-26-2010 |
| 20100220740 | METHOD, SYSTEM, AND PROGRAM FOR FORWARDING MESSAGES BETWEEN NODES - Provided are a method, system, and program for forwarding a message from a transmitting node. A first message is received encoded using a first communication protocol from the transmitting node, wherein the first message includes a direct reference to a memory location in one node. A determination is made as to whether the first message is directed to a receiving node using a second communication protocol. A second message is generated that is compatible with the second communication protocol, wherein the second message causes an operation to be performed with respect to the direct reference in the first message. The second message is transmitted to the receiving node. | 09-02-2010 |
| 20110135303 | DIRECT MODE ADAPTER BASED SHORTCUT FOR FCoE DATA TRANSFER - This invention permits all FCoE (Fibre Channel over Ethernet) frames to be transferred from one FCoE network adapter to another without having to traverse through a Fiber Channel Forwarder (FCF) device. After the FCF is determined not to be present, a logical End-To-End connection is established between Peer FCoE Adapters. This invention permits an FCoE message originating at an FCoE network adapter to be sent to an FCoE receiving adapter across “Ethernet” links and switches, or via a single “Ethernet” link (Point-To-Point) but without having to pass through FCF devices. | 06-09-2011 |
