1Introduction
This chapter describes the audience for this guide and outlines the OpenStack
architecture.
Audience
This guide is intended for OpenStack (Juno, Kilo, Liberty, and Mitaka) users who
want to configure single root input/output virtualization (SR-IOV) with the QLogic
3400/8400/45000 Series Adapters.
What is OpenStack?
The OpenStack project is an open source cloud computing platform that supports
all types of cloud environments and works as infrastructure as a service (IAAS).
The technology consists of a series of interrelated projects that control pools of
processing, storage, and networking resources throughout a data center, which
users manage through a web-based dashboard, command line tools, or
representational state transfer (REST) APIs.
OpenStack (starting with Juno) adds inbox support to request virtual machine
(VM) access to the virtual network through SR-IOV NIC. With the introduction of
SR-IOV-based NICs, each SR-IOV port is associated with virtual functions (VFs).
SR-IOV ports are provided by hardware-based virtual Ethernet bridging (HW
VEB).
NOTE
At the time of publication, support for the 45000 Series Adapters is limited to
the FastLinQ™QL4521x25GbE Adapters.

2Example Architecture
This chapter describes the OpenStack 3 node architecture.
OpenStack Nodes
This guide is intended for use with OpenStack 3 node architecture, which consists
of the following nodes:
Controller
Compute
Network
These nodes are described in the following sections.
Controller Node
In the example architecture used in this guide, the Controller node runs the
Identity service (Keystone), Image Service (Glance), management portions of the
Compute service (Nova Management) and Networking service (Neutron
Server/modular layer 2 (ML2) plug-in), networking plug-in, and the dashboard
(Horizon). The architecture also includes supporting services such as a database
(mysql), message broker (Rabbitmq), and network time protocol (NTP).
Compute Node
The Compute node runs the hypervisor portion of Compute, which operates
tenant virtual machines.
In this architecture, the Compute node uses a kernel-based virtual machine (KVM)
as the hypervisor (KVM is the default hypervisor). The Compute node runs the
Networking node plug-in (ML2), layer 2 agent open virtual search (OVS), and NIC
switch agent (SR-IOV switch).
Network Node
The Network node runs the Networking plug-in (ML2), layer 3 agent, and DHCP
agent. This node also handles external (Internet) connectivity for tenant VMs or
the Compute node.

3Prerequisites
This chapter describes what you need to use OpenStack with SR-IOV
configuration using the QLogic 3400/8400/45000 Series Adapters.
You need the following knowledge and equipment:
One or more QLogic 3400/8400/45000 Series Adapters
An understanding of OpenStack deployment and experience with
OpenStack 3 node configuration using flat mode networking with virtual LAN
(VLAN) with the ML2/OVS plug-in for public and private (that is, net1)
networks.
More information about OpenStack 3 node configuration on Red Hat®7 can
be found at the following locations:
OpenStack (Juno):
http://docs.openstack.org/juno/install-guide/install/yum/content/
OpenStack (Kilo):
http://docs.openstack.org/kilo/install-guide/install/yum/content/
Open Stack (Liberty)1
http://docs.openstack.org/liberty/install-guide-rdo/
Open Stack (Mitaka)1
http://docs.openstack.org/mitaka/install-guide-rdo/
The Compute node must have one or more QLogic 3400/8400/45000 Series
Adapters present in system with SR-IOV support enabled.
NOTE
At the time of publication, support for the 45000 Series Adapters is
limited to the FastLinQ QL4521x25GbE Adapters.
1The OpenStack configuration described in this link uses VXLAN and Linux Bridge agent.
However, the QLogic SR-IOV configuration uses and has been tested only with OpenStack 3 node
configuration with VLAN and open vSwitch (OVS). Furthermore, be sure to configure the
OpenStack 3 node configuration with kernel-based virtual machine (KVM).

3–Prerequisites
4 83840-546-02 B
For the VM instance, QLogic uses a Red Hat 7 KVM Guest image to test
SR-IOV configurations that support the 3400/8400/45000 Series Adapters’
inbox or out-of-box driver, as described here:
http://docs.openstack.org/image-guide/content/ch_obtaining_images.html
OpenStack 3 node configuration without SR-IOV support must work with flat
networking/VLAN. You must be able to assign floating IP access and log in
to the VM.

Configuring SR-IOV on the Controller Node
Since the Neutron server is running on the Controller node, the file configuration
for the Neutron server must be changed to enable SR-IOV, as described in the
following procedure.
To configure SR-IOV on the Controller node:
1. Modify the ML2 Neutron plug-in by editing the
/etc/neutron/plugins/ml2/ml2_conf.ini file on Controller node as
follows:
[ml2]
tenant_network_types = flat,vlan
type_drivers = vlan
mechanism_drivers = openvswitch,sriovnicswitch
[ml2_type_vlan]
network_vlan_ranges = physnet2:1000:2000,physnet3:2001:2100
[securitygroup]
firewall_driver = neutron.agent.firewall.NoopFirewallDriver
2. Add the supported PCI vendor VF devices defined by
vendor_id:product_id according to the PCI ID Repository by editing
the /etc/neutron/plugins/ml2/ml2_conf_sriov.ini file as
follows:
[ml2_sriov]
supported_pci_vendor_devs = 14e4:16xx (3400 and 8400 Series
Adapters)
supported_pci_vendor_devs = 1077:16xx (45000 Series Adapters)
3. Modify the ml2_conf_sriov.ini file to add the following statement:
