VXLAN Configuration with
the QLogic
3400/8400/45000 Series
Adapters
This chapter describes how to install packages, configure the system, and
configure VXLAN using the QLogic 3400/8400/45000 Series Adapters.
QLogic FastLinQ 3400/8400/45000 Series Adapters deliver assists and offloads
for VXLAN in OpenStack deployments that enable efficient distribution of network
transmit and receive processing for VXLAN traffic across servers with multiple
CPU cores. With QLogic VXLAN Overlay acceleration, the adapters provide the
ability to distribute workloads efficiently across all processor cores and deliver
maximum performance without burdening the host CPU.
QLogic recommends updating the 3400/8400 Series networking driver to the
latest available out-of-box driver (see
“Downloading Updates” on page viii ) for
maximum performance in OpenStack VXLAN deployments.
