摘要:
A system area network computer system architecture is structured as a single system image cluster operating system to offer an opportunity to increase the availability to I/O devices in the system. The computing system comprises a number of processor units coupled to a plurality of input/output (I/O) elements by a routing fabric that provides each of the processor elements with access to any one of the I/O elements. Using a Transparent Network Computing extension to a highly available version of UNIX System V Release 4.2, the system provides a higher degree of availability to I/O devices by providing for the takeover of their controlling entity.

摘要:
A coherency manager provides coherent access to shared data by receiving a copy of updated database data from a host computer through RDMA, the copy including updates to a given database data; storing the copy of the updated database data as a valid copy of the given database data in local memory; invalidating local copies of the given database data on other host computers through RDMA; receiving acknowledgements from the other host computers through RDMA that the local copies of the given database data have been invalidated; and sending an acknowledgement of receipt of the copy of the updated database data to the host computer through RDMA. When the coherency manager receives a request for the valid copy of the given database data from a host computer through RDMA, it retrieves the valid copy of the given database data from the local memory and returns the valid copy through RDMA.

A method of providing a converged InfiniBand over Ethernet (IBOE) network. An IBOE switch receives a data packet. If the data packet is received by the IBOE switch from the InfiniBand network, a translation utility looks up an Ethernet media access control (MAC) address corresponding to an LID of the packet in a translation table. The translation utility generates an Ethernet packet and encapsulates an InfiniBand link layer packet before sending the packet. If the data packet is received by the IBOE switch from the Ethernet network, the translation utility removes the Ethernet header from the packet and looks up a LID corresponding to the MAC address. The translation utility calculates an outbound port number and sends the packet.

摘要:
A method of providing visibility of Ethernet components to a subnet manager in a converged InfiniBand over Ethernet (IBOE) network. If a port of an IBOE gateway corresponds to one or more InfiniBand devices, the subnet manager sends fabric management packets (FMPs) to discover the InfiniBand network and assigns physical local identifiers (LIDs) to the InfiniBand devices. If a port of the IBOE gateway corresponds to one or more Ethernet devices, the subnet manager sends FMPs to discover the Ethernet network. The subnet manager adds the Ethernet Media Access Control (MAC) addresses of any responding devices to an LID routing table and assigns LIDs to the Ethernet devices. The subnet manager configures one or more virtual Host Channel Adapters (HCAs) corresponding to the one or more Ethernet MAC addresses in the LID routing table.
