摘要： A shared network interface controller (NIC) interfaces a plurality of operating system domains as part of the load-store architecture of the operating system domains. A bus interface couples the NIC to a load-store domain bus (such as PCI-Express), using header information to associate data on the bus with an originating operating system domain. Transmit/receive logic connects the NIC to the network. Association logic allows the NIC to designate, and later lookup which destination MAC address (on the Ethernet side) is associated with which operating system domain. Descriptor register files and Control Status Registers (CSR's) specific to an operating system domain are duplicated and made available for each domain. Several direct memory access (DMA) engines are provided to improve throughput. Packet replication logic, filters (perfect and hash) and VLAN tables are used for looping back packets originating from one operating system domain to another and other operations.

摘要： A high speed connection apparatus, method, and system is provided for peripheral components on digital computer systems. The peripheral component interconnect (PCI) specification is used as a baseline for an extended set of commands and attributes. The extended command and the attribute are issued on the bus during the clock cycle immediately after the clock cycle when the initial command was issued. The extended commands and attributes utilize the standard pin connections of conventional PCI devices and buses making the present invention backward-compatible with existing (conventional) PCI devices and legacy computer systems. The conventional PCI command encoding is modified and the extended command is used to qualify the type of transaction and the attributes being used by the initiator of the transaction. The extended commands are divided into four groups based upon the transaction type and the extended command type. Transactions are either byte count or byte-enable transaction types. Extended command types are either validated or immediate. Some extended command encodings are reserved but can be assigned in the future to new extended commands that will behave predictable with current devices.

摘要： A Fibre Channel controller shareable by a plurality of operating system domains (OSDs) is disclosed. The controller includes a programming interface, located within a system load-store memory map of each OSD by which the OSDs request the controller to perform I/O operations with remote FC devices. The programming interface includes a distinct control/status register (CSR) bank for each of OSD. The OSDs execute load-store instructions addressed to the programming interface to request the I/O operations. Selection logic selects as a target of each of the load-store transactions the distinct CSR bank for the OSD that executed the corresponding load-store instruction. An FC port obtains a distinct FC port identifier for each OSD and transceives FC frames with the remote FC devices using the distinct FC port identifier for each OSD in response to the I/O operation requests. In one embodiment, multiple blade servers share the controller via a shared I/O switch.
