Offline Deployment
Cisco Smart PHY software image is a compressed tarball file that contains all the scripts, helm charts, and container images required for installing the Cisco Operations Hub cluster and the Cisco Smart PHY application. It also contains a copy of these instructions and configuration examples.
Use the deployer
script available in the software image to set up the Deployer virtual machine (VM) and clusters.
The installation process creates the following components:
-
Deployer: The controller used to configure and deploy the cluster.
-
Cisco Operations Hub Cluster: The Cisco Smart PHY application runs on this cluster.
The Deployer VM supports two types of Cisco Smart PHY deployments:
-
All-in-one (AIO) cluster: Runs as a single VM.
-
Multinode cluster: Consists of 12 VMs deployed across three VMware ESXi hosts. Each VMware ESXi host server hosts a control-plane VM, etcd VM, Infra VM, and Operations VM.
The multinode cluster provides complete support for high availability (HA) and supports two sizes of clusters: small and normal for production environments. The default size is small, when the
size
is not specified.For the current number of RPDs supported on the Cisco Smart PHY application, we recommend the small multinode cluster for production deployments due to their increased resiliency.
The following table shows the minimum resources for deployer and AIO.
