Appl. No.:

09/886186

Inventors:

David Craddock - New Paltz NY, US
Charles Graham - Rochester MN, US

International Classification:

G06F015/16

US Classification:

709/200000

Abstract:

An apparatus and method for an advanced tunneling technique to allow Internet Protocol (IP) frames to be routed through System Area Network (SAN) components with little or no overhead are provided. Furthermore, an apparatus and method for processing Internet Protocol (IP) version 6 datagrams over a SAN using basic raw and unreliable datagram (RawD and UD respectively) interfaces are provided. The apparatus and method allows a host channel adapter (HCA) to attach directly to an IP router which supports multiple link protocols, for example a router than attaches InfiniBand (IB) links and Ethernet links, and uses IP as the networking protocol on both. In this way, a SAN may be coupled to a LAN via a router with minimal hardware and overhead.

International Classification:

G06F015/16

US Classification:

709/212000

Abstract:

A mechanism for initiating and completing one or more I/O transactions using memory semantic messages in a system area network is disclosed. Memory semantic messages are transmitted by means of a remote direct memory access (RDMA) operation; they are more akin to a memory copy than a simple “channel semantic” transmission of a message. The use of memory semantic input/output in this way facilitates the migration of input/output adapters from a memory-mapped interface, such as Peripheral Component Interconnect (PCI), to a system area network.

Thomas A. Gregg - Highland NY, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 12/00

US Classification:

711206

Abstract:

Disclosed are a method and system for address translation with memory windows. The method comprises the steps of designating a memory region having a set of virtual addresses, each virtual address having an associated real address; and providing one or more translation tables for translating the virtual addresses to the real addresses; A memory region protection table entry (MRPTE) defines access rights for the memory region, and includes one or more pointers to the one or more translation tables. A memory window is bound to the memory region to provide access to a subset of the virtual addresses. A memory window protection table entry (MWPTE) defines access rights for the memory window, and includes one or more pointers to the one or more translation tables to translate the subset of virtual addresses to real addresses.

International Classification:

G06F 9/445

US Classification:

717171

Abstract:

A firmware update process for a self-virtualizing IO resource such as an SRIOV adapter is incorporated into a platform firmware update process to systematically update the resource firmware in a manner that is for the most part transparent to the logical partitions sharing the adapter. In particular, resource firmware associated with a self-virtualizing IO resource is bundled with firmware for at least one adjunct partition associated with that self-virtualizing IO resource within a common firmware image so that, upon restart of the adjunct partition to use the updated firmware image, the resource firmware is also updated, with a logical partition that uses the self-virtualizing IO resource maintained in an active state during the restart, and without requiring the self-virtualizing IO resource to be deconfigured from the logical partition.

Charles R. Graham - Glenshaw PA

Assignee:

PPG Industries, Inc. - Pittsburgh PA

International Classification:

H05K 900

US Classification:

174 35R

Abstract:

Nonorthogonal grid patterns and curved transparencies having nonorthogonal grid patterns comprising a matrix of interconnected circles and arcs are described for use as electromagnetic pulse shielding elements which diminish "starburst" light interference distortions and readily conform to compound curvatures and complex shapes.
