Post deployment tasks

Post deployment tasks overview
After you deploy Rancher on NetApp HCI, you should continue with post-deployment
activities.
• Ensure Rancher Support parity
• Improve Rancher VM resiliency
• Configure monitoring
• Install Trident
• Enable Trident support for user clusters

Ensure Rancher Support parity
After you deploy Rancher on NetApp HCI, you need to ensure that the number of
Rancher Support cores you purchased matches the number of CPU cores you are using
for Rancher management VMs and user clusters.
If you purchased Rancher Support for only part of your NetApp HCI compute resources, you need to take
action in VMware vSphere to ensure that Rancher on NetApp HCI and its managed user clusters are only
running on hosts for which you have purchased Rancher Support. See the VMware vSphere documentation for
information about how to help ensure this by confining compute workloads to specific hosts.

Improve Rancher VM resiliency
After you deploy Rancher on NetApp HCI, your vSphere environment will contain three
new nodes as virtual machines to host the Rancher environment. The Rancher web UI is
available from each of these nodes. For full resiliency, each of the three virtual machines
along with the corresponding virtual disks should reside on a different physical host after
