Installing the Cisco NFVI Hardware
Before installing Cisco Virtualization Infrastructure Manager (VIM), switch on the Cisco UCS C-Series or B-Series harware. Depending upon the pod type, the CIMC connection or UCSM IP has to be set up ahead of time. Following table lists the UCS hardware options and network connectivity protocol that can be used with either virtual extensible LAN (VXLAN) over a Linux bridge, VLAN over OVS or VLAN over VPP. If Cisco Virtual Topology Services, an optional Cisco NFVI application, is installed, Virtual Topology Forwarder (VTF) can be used with VXLAN for tenants, and VLANs for providers on C-Series pods.

Note |
The storage nodes boot off two internal SSDs. It also has four external solid state drives (SSDs) for journaling, which gives a 1:5 SSD-to-disk ratio (assuming a chassis that is filled with 20 spinning disks). Each C-Series pod has either a 2 port 10-GE Cisco vNIC 1227 card or 2 of 4 port Intel 710 X card. UCS M4 blades only support Cisco 1340 and 1380 NICs. For more information about the Cisco vNICs, see LAN and SAN Connectivity for a Cisco UCS Blade. Cisco VIM has a micro pod (based on UCS M4 hardware) which works on Cisco VIC 1227 or Intel NIC 710, with OVS/VLAN or VPP/VLAN as the virtual network protocol. The micro pod supports users with a small, functional, but redundant cloud with capability of adding standalone computes to an existing pod. The manifestation of the UCS-M4 micro-pod works on Cisco VIC (1227) or Intel NIC 710, with OVS/VLAN of VPP/VLAN as the virtual network protocol. |
Cisco VIM supports M4-based micropod on a VIC/NIC system with OVS, to extend the SRIOV support on a 2x2-port Intel 520 NIC card. Also, the M5 based Micro pod is based on Intel NIC 710, and supports SRIOV over XL710, with OVS/VLAN or VPP/VLAN as the virtual network protocol. In Cisco VIM 2.4.1, we have added the support of M5-based micropod on a VIC/NIC system, to extend the SRIOV support on a 2x2 port Intel XL710 NIC card.
In addition, the Cisco Nexus 9372 or 93180YC, or 9396PX must be available to serve the Cisco NFVI ToR function.
After verifying that you have the required Cisco UCS servers and blades and the Nexus 93xx, install the hardware using the following links:
The following figure shows a C-Series Cisco NFVI pod. Although the figure shows that a full complement of UCS C220 computes nodes, the number of compute nodes can vary, depending on the implementation requirements. The UCS C220 control and compute nodes can be replaced with UCS 240 series. However in that case the number of computes fitting in one chassis system is reduced by half.
Note |
The combination of UCS-220 and 240 within the compute and control nodes is not supported. |
