摘要:
A hardware switch for use with hypervisors and blade servers is disclosed. The hardware switch enables switching to occur between different guest OSs running in the same server, or between different servers in a multi-root IOV system, or between different guest OSs running in the same server in single-root IOV systems. Whether embedded in a host bus adapter (HBA), converged network adapter (CNA), network interface card (NIC) or other similar device, the hardware switch can provide fast switching with access to and sharing of at least one external network port such as a Fibre Channel (FC) port, 10 Gigabit Ethernet (10 GbE) port, FC over Ethernet (FCoE) port, or other similar port. The hardware switch can be utilized when no hypervisor is present or when one or more servers have hypervisors, because it allows for switching (e.g. Ethernet switching) between the OSs on a single hypervisor.

摘要:
An intelligent network processor is disclosed that provides a PCI express (PCIe) host bus adapter with firmware selectable hardware capabilities and firmware enabled emulation of capabilities not supported by hardware. Support for Fibre Channel (FC) and Gigabit Ethernet (GbE) protocols are provided through the same fabric ports, including multiple port trunking for both protocols. On chip protocol conversion is provided for switching and routing between FC and GbE ports. Switching using the same crossbar module is provided for both FC and GbE protocols. The crossbar module is coupled to directly access external DDR memory so that messages from FC, GbE, and PCIe interfaces may be switched directly to the DDR memory.
