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： A shared I/O subsystem that includes a plurality of I/O interfaces for coupling a plurality of computer systems where each of I/O interfaces communicatively couples one of the computer systems to the shared I/O subsystem. The shared I/O subsystem receives, at a first one of the I/O interfaces, a data packet from one of the computer systems coupled to the first one of the I/O interfaces where the data packet has a variable length, arranges, at the first one of the I/O interfaces, the data packet into an internal format where the internal format has a first portion that includes data bits and a second portion that includes control bits, receives the data packet in a buffer in the shared I/O subsystem where the second portion is received after the first portion, verifies, with the shared I/O subsystem, that the data packet has been completely received by the buffer by monitoring a memory bit aligned with a final bit in the second portion of the data packet, and transmits, in response to the verifying, the data packet to another one of the computer systems coupled to a second one of the I/O interfaces.

摘要： A computer system that includes a plurality of servers, and a shared I/O subsystem coupled to each of the servers and to one or more I/O interfaces. The shared I/O subsystem services I/O requests made by two or more of the servers. Each I/O interface may couple to a network, appliance, or other device. The I/O requests serviced by the shared I/O subsystem may alternatively include software initiated or hardware initiated I/O requests. Different servers coupled to the shared I/O subsystem may use different operating systems, and each I/O interface may be used by two or more servers.

摘要： A shared I/O subsystem for a plurality of computer systems where a plurality of virtual I/O interfaces 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 also includes a plurality of I/O interfaces and a forwarding function. The forwarding function includes a plurality of forwarding table entries that logically arrange the shared I/O subsystem into one or more logical switches. Each of the logical switches communicatively couples one or more of the virtual I/O interfaces to one of the I/O interfaces. A logical switch receives a first I/O packet from one of the virtual I/O interfaces and directs the first I/O packet to at least one of the I/O interface and one or more of other ones of the virtual I/O interfaces. A logical switch also receives a second I/O packet from the I/O interface and directs the second I/O packet to one or more of the virtual I/O interfaces.

摘要： A shared I/O subsystem for a plurality of computer systems. The shared I/O subsystem includes a plurality of ports that communicatively couple the computer systems to the shared I/O subsystem where each of the ports includes at least one corresponding bit in an adjustable span port register. Data packets arriving on the plurality of ports may be selectively provided to a span port based on a current state of the adjustable span port register.
