  • Patent number: 9736070
    Abstract: In one embodiment, a server includes a processor and logic integrated with and/or executable by the processor. The logic is configured to hash at least a portion of a packet according to a hashing algorithm to obtain a hash value. The logic is also configured to select an uplink with which to forward the packet based on the hash value. In another embodiment, a method includes hashing at least a portion of at least one packet according to a hashing algorithm to obtain a hash value using an accelerated network interface card (NIC) of a server. The accelerated NIC is configured to provide overlay functionality. The method also includes selecting an uplink, based on the hash value, from a plurality of uplinks available to send traffic out to a network using the accelerated NIC.

  • Patent number: 9172557
    Abstract: A system includes a server including: logic adapted for receiving traffic from a virtual machine (VM), the traffic including at least one packet, logic adapted for hashing at least a portion of the at least one packet according to a hashing algorithm to obtain a hash value, and logic adapted for selecting an uplink based on the hash value; at least one accelerated network interface card (NIC), each accelerated NIC including: network ports including multiple Peripheral Component Interconnect express (PCIe) ports adapted for communicating with the server and a network, each network port including an uplink, logic adapted for encapsulating the at least one packet into an overlay-encapsulated packet, logic adapted for storing a media access control (MAC) address corresponding to the selected uplink as a source MAC (SMAC) address in an outer header of the overlay-encapsulated packet, and logic adapted for sending the overlay-encapsulated packet via the selected uplink.
