摘要： A transaction switch and integrated circuit incorporating said for switching data through a shared memory between a plurality of data interfaces that support different data protocols, namely packetized interfaces like InfiniBand and addressed data interfaces like PCI. The transaction switch also switches transactions commanding data transfers between the disparate protocol data interfaces and between those of the data interfaces having like protocols. For example, the transaction switch enables a hybrid InfiniBand channel adapter/switch to perform both InfiniBand packet to local bus protocol data transfers through the shared memory as well as InfiniBand packet switching between the multiple InfiniBand interfaces. The transactions are tailored for each interface type to include information needed by the particular interface type to perform a data transfer. The shared buffer memory, dynamically allocated by the transaction switch on a first-come-first serve basis, results in more efficient use of precious buffering resources than in a statically allocated scheme.

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 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.
