Data Center Requirements

Cisco Optical Network Controller 26.1.x can be deployed using VMware vCenter server version 7.0, 8.0, and 9.0 and vSphere server and client with version 7.0, 8.0, and 9.0. It is deployed on rack or blade servers within vSphere. To aid in the deployment, Cisco has developed a cluster installation tool. This tool works in both environments.

The following list contains the prerequisites of Cisco Optical Network Controller 26.1.x installation.

● Before installing Cisco Optical Network Controller 26.1.x, you must log in to the VMware customer center and download VMware vCenter server version 7.0, 8.0, and 9.0, as well as vSphere server and client with version 7.0, 8.0, and 9.0. Cisco Optical Network Controller 26.1.x is deployed on rack or blade servers within vSphere.

● ESXi host must be installed on servers with vSphere version of 7.0, 8.0, and 9.0 to support creating Virtual Machines (VM).

● Before the installation of Cisco Optical Network Controller 26.1.x, three networks must be created.

◦ Control Plane Network:

The control plane network helps in internal communication between the deployed VMs within a cluster. If you are setting up a standalone system, this can refer to any private network.

◦ VM Network or Northbound Network:

The VM network is used for communication between the user and the cluster. It handles all the traffic to and from the VMs running on your ESXi hosts and this is your public network through which the UI is hosted.

◦ Eastbound Network:

The Eastbound network can be a private network for standalone setups. It requires one private IP address, a gateway, and a DNS server. If the node is not exposed to the internet, the DNS server must be an internal DNS, otherwise you can use an internet DNS.

Hardware Requirements

This table lists the minimum hardware requirements for the base profile in HA mode with daily retention only.

vCPU to Physical CPU Core Ratio

We support a vCPU to Physical CPU core ratio of 2:1 if hyperthreading is enabled and the hardware supports hyperthreading. Hyperthreading is enabled by default on Cisco UCS servers that support hyperthreading. In other cases, the vCPU to Physical CPU core ratio is 1:1.

The requirements based on type of deployment are given in this table:

Table 11. Table 4. VM Host Requirements

Deployment Type	Requirements
Standalone ( SA )	Control Plane: 1 IP ( this can be a private network). Northbound Network/VM Network: 1 IP (this must be a public network) Eastbound Network: 1 IP ( this can be a private network).

Deployment Type

Requirements

Standalone ( SA )

Control Plane: 1 IP ( this can be a private network).

Northbound Network/VM Network: 1 IP (this must be a public network)

Eastbound Network: 1 IP ( this can be a private network).

Table 12. Table 4. VM Host Requirements

Product	Supported release
Additional Storage	10 GB (approximately) of storage is required for OVA installation.
Network Connections	For production deployments, we recommend that you use three interfaces, one each for the Eastbound, Northbound, and Control Plane networks. For optimal performance, the Eastbound, Northbound networks should use links configured at a minimum of 1 Gbps with latency less than 100 ms. The Control Plane Network must have a 10 Gbps link.
IP Addresses	Three IP subnets, Control Plane, Northbound Network, Eastbound Network are necessary. ● The IP addresses must be able to reach the gateway address for the network where Cisco Optical Network Controller Data Gateway is installed, or the installation fails. At this time, your IP allocation is permanent and cannot be changed without re-deployment. For more information, contact your Cisco Customer Experience team.
NTP Servers	The IPv4 addresses or host names of the NTP servers you plan to use. If you want to enter multiple NTP servers, separate them with spaces. These should be the same NTP servers you use to synchronize the Cisco Optical Network Controller application VM clock, devices, clients, and servers across your network. ● Ensure that the NTP servers are reachable on the network before attempting installation. The installation will fail if the servers cannot be reached. ● The ESXi hosts that will run the Cisco Optical Network Controller application and Cisco Optical Network Controller Data Gateway VM must have NTP configured, or the initial handshake may fail with "certificate not valid" errors.
DNS Servers	The IPv4 addresses of the DNS servers you plan to use. These should be the same DNS servers you use to resolve host names across your network. Ensure that the DNS servers are reachable on the network before attempting installation. The installation will fail if the servers cannot be reached.
DNS Search Domain	The search domain you want to use with the DNS servers, for example, cisco.com. You can have only one search domain.

Important Notes

Cisco Optical Network Controller Infrastructure and applications are built to run as a distributed collection of containers managed by Kubernetes. The number of containers varies as applications are added or deleted.
