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： A rate limiter incorporated in a server connected to a network. The rate limiter is adapted to reduce congestion in the network in response to a congestion notification message. The server is adapted to send packets over the network. The rate limiter includes at least one of: a server rate limiter engine adapted to rate limit the packets in response to the server; a virtual machine rate limiter engine adapted to rate limit the packets in response to a virtual machine associated with the packets, the virtual machine hosted by the server; a flow rate limiter engine adapted to rate limit the packets in response to a flow associated with the packets; the flow being one of a plurality of flows transporting packets over the network; and a transmit engine adapted to rate limit the packets in response to a virtual pipe of the network for transmitting the packets.
