摘要： An apparatus and method for sharing I/O devices. The apparatus has a first plurality of I/O ports, a second I/O port, and core logic. The first plurality is coupled to a plurality of operating system domains through a load-store fabric. Each of the first plurality routes transactions between the operating system domains and the switching apparatus. The second I/O port is coupled to a first shared input/output endpoint. The first shared input/output endpoint requests/completes transactions for each of the plurality of operating system domains. The core logic is coupled to the first plurality of I/O ports and the second I/O port. The core logic routes the transactions between the first plurality of I/O ports and the second I/O port and associates each of the transactions with a corresponding one of the plurality of operating system domains (OSDs) by encapsulating an OS domain header within a transaction layer packet.

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 includes a plurality of control/status register (CSR) banks. A respective one of the CSR banks is used by each OSD to request the controller to perform I/O operations with remote FC devices. A load-store bus interface receives from a load-store bus load and store transactions from each OSD. Each transaction includes an OSD identifier identifying the OSD that initiated the transaction. The bus interface directs the transactions to the respective CSR bank based on the OSD identifier. A 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, the controller includes a shared I/O switch coupling the OSDs thereto.

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 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： A method enabling I/O devices to be shared among multiple operating system domains, including first communicating with each of the operating system domains according to a protocol that provides exclusively for a single system domain ithin the load-store fabric; and second communicating with the shared I/O endpoint according to a variant of the protocol to enable the shared I/O endpoint to associate a prescribed operation with a corresponding one of the independent operating system domains. The second communicating includes encapsulating an OS domain header within a transaction layer packet that otherwise comports with the protocol, wherein the value of the OS domain header designates the corresponding one of the operating system domains; and via core logic within a swithching apparatus, mapping the independent operating system domains to the shared I/O endpoint.
