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 Fibre Channel (FC) controller shareable by a plurality of operating system domains (OSDs) within a load-store architecture is disclosed. The controller has a FC port that obtains a plurality of FC port identifiers for association with respective ones of the OSDs. A load-store bus interface is the target of a load-store transaction on a load-store bus from each OSD. The load-store transaction includes a command to perform an I/O operation with a remote FC device. Association logic populates an S_ID field of a FC frame with the FC port identifier associated with the respective OSD that initiated the command. The FC port transmits the FC frame on the FC port to the remote FC device. In one embodiment, the controller interfaces to an Advanced Switching fabric to receive packets encapsulating load-store transactions from the OSDs. Each packet includes an identifier identifying the OSD initiating the transaction.

摘要： An apparatus and method is provided for allowing I/O devices to be shared and/or partitioned among a plurality of processing complexes within the load/store fabric of each of the processing complexes without requiring modification to the operating system or driver software of the processing complexes. The apparatus and method includes a switch for selectively coupling each of the processing complexes to one or more shared I/O devices. The apparatus and method further includes placing information within packets transmitted between the switch and the I/O devices to identify which of the processing complexes the packets are associated with. The invention further includes an apparatus and method within the shared I/O devices to allow the shared I/O devices to service each of the processing complexes independently.

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.

摘要： An apparatus and method is provided for interfacing a number of computer servers (or operating system domains) to a network such as Ethernet through a shared network interface controller (NIC) which is part of the load-store architecture of the operating system domains. The network interface controller includes a bus interface to couple the controller to a load-store domain bus (such as PCI-Express), the bus including header information to associate data on the bus with an originating operating system domain. The controller also includes transmit/receive logic to connect it to the network. In between the bus interface and the transmit/receive logic is buffering to temporarily store data coming either from the operating system domains or the network. The buffered data is tagged within an identifier to associate it with one or more of the operating system domains. Association logic is further provided to allow the controller to designate, and later lookup which destination MAC address (on the Ethernet side) is associated with which operating system domain. Control Status Registers (CSR's) specific to an operating system domain are duplicated and made available for each domain. Descriptor Register files are also duplicated for each operating system domain. A number of direct memory access (DMA) engines are provided to improve throughput. And, packet replication logic, along with filters (perfect and hash) and VLAN tables are used for looping back packets originating from one of the operating system domains to one or more of the other operating system domains, for server to server communication, multicast and broadcast operations.

摘要： An apparatus and method is provided for allowing one or more processing complexes to share a disk controller, particularly a serial ATA (SATA) controller. Each processing complex utilizes its own load-store domain to couple to the shared SATA controller, either directly, or indirectly through a shared I/O switch. Ultimately, requests from the processing complexes are presented to the switch with operating system domain header (OSD header) information so that the shared SATA controller can determine which request came from which processing complex, and allocate resources accordingly. Upstream responses from the shared SATA controller include the OSD header so that the shared I/O switch can accurately route the responses to their respective processing complexes. The shared SATA controller includes OSD ID logic to determine the source/result of packets, one or more task files to support multiple processing complexes, and one or more DMA engines to improve performance for requests from multiple processing complexes.
