摘要： A shared I/O subsystem that couples a plurality of computer systems to at least one shared I/O interface. The shared I/O subsystem includes a plurality of virtual I/O interfaces that are communicatively coupled to the computer systems. Each of the computer systems includes a virtual adapter that communicates with one of the virtual I/O interfaces. The shared I/O subsystem further includes a forwarding function having a forwarding table. The forwarding table includes a plurality of entries corresponding to each of the virtual I/O interfaces. The forwarding function receives a first I/O packet from one of the virtual I/O interfaces and uses the forwarding table to direct the first I/O packet to at least one of a physical adapter associated with the at least one shared I/O interface and one or more of other ones of the virtual I/O interfaces. The forwarding function also receives a second I/O packet from the physical adapter and uses the forwarding table to direct the second I/O packet to one or more of the virtual I/O interfaces.
摘要翻译：将多个计算机系统耦合到至少一个共享I / O接口的共享I / O子系统。共享I / O子系统包括通信地耦合到计算机系统的多个虚拟I / O接口。每个计算机系统包括与虚拟I / O接口中的一个通信的虚拟适配器。共享I / O子系统还包括具有转发表的转发功能。转发表包括对应于每个虚拟I / O接口的多个条目。所述转发功能从所述虚拟I / O接口之一接收第一I / O分组，并且使用所述转发表将所述第一I / O分组引导到与所述至少一个共享I / O相关联的物理适配器中的至少一个接口和虚拟I / O接口中的一个或多个。转发功能还从物理适配器接收第二I / O分组，并使用转发表将第二I / O分组引导到一个或多个虚拟I / O接口。
