One way of demonstrating the concept of ‘Invisible Infrastructure’ is the ability to complete a full system upgrade with minimal service interruption. In this post I will show the “One Click” upgrade facility that’s available on the Nutanix platform. This facility allows the admin to upgrade the Nutanix Operating System (NOS), the hypervisor, any required storage firmware and appropriate version of Nutanix Cluster Check (NCC) for the target NOS release.
The Nutanix platform upgrade takes care of all the intermediate steps and just works, regardless of the size of the cluster. There’s minimal impact and disruption as the upgrade takes place and it enables you to carry out such tasks within normal working hours, and not losing a weekend to the usual rigours of a traditional hardware upgrade cycle.
