Which two network segments are needed to support Cisco VIM? (Choose two.)

Cisco Virtualized Infrastructure Manager (Cisco VIM) must always have a Provisioning network so that servers can be discovered, PXE-booted, and imaged, and it must have a dedicated Storage network to interconnect the integrated Ceph cluster that stores OpenStack images, volumes, and back-end data. All other segments (Data-plane/Tenant, Host/OAM, or Heartbeat/Cluster) are optional or can be collapsed onto another VLAN in small or brown-field deployments; therefore only Provisioning and Storage are strictly required to support (i.e., bring-up and operate) Cisco VIM itself.

B. Data plane – Carries tenant VM traffic; optional and not required for Cisco VIM installation/operation.

C. Heartbeat – Cluster/HA VLAN can reuse Storage or OAM; not classed as mandatory.

D. Host – Management/OAM VLAN may be combined with Provisioning or omitted in minimal designs; not always mandatory.

1. Cisco Virtualized Infrastructure Manager (CVIM) Installation Guide 4.2, “Network Requirements”, Table 2 Mandatory VLANs: Provision (PXE) and Storage; other VLANs marked ‘optional’.

2. Cisco NFV Infrastructure Solution Reference Architecture 5.0, Sec. 3.2 “Network Segmentation”—lists Provision and Storage as “required”, others “optional/conditional”.

3. Cisco Live BRKSPM-1268, slide 25 “CVIM Required Networks” – shows only Provision and Storage in the Required column.

4. R. Kumar et al., “Design and Deployment of Cisco CVIM for NFVI,” IEEE/IFIP NOMS 2018 Workshops, pp. 1-3—identifies PXE/Provision and Ceph Storage as essential back-plane networks.
