As the name says, it’s a One-Click NOS upgrade for the entire Nutanix cluster. Nutanix one-click upgrade automatically indicates when a new NOS version is available and it will auto-download the binaries if the auto-download option is enabled. With a single-click to upgrade all nodes in a cluster Nutanix will use a highly parallel process and reboot one CVM at a time using a rolling upgrade mechanism. The entire cluster upgrade can be fully monitored by the administrator.
During the upgrade process a feature called Autopathing kicks in redirecting VM I/Os on that Hypervisor host to another CVM (Nutanix Controller) on a different hypervisor host. This has several benefits including allowing you to upgrade the NOS on a CVM without disruption.
The new and improved CVM AutoPathing 2.0 prevents performance loss during rolling upgrades minimizing I/O timeout by pre-emptively redirecting storage traffic to other CVMs. Failover traffic is automatically load-balanced with the rest of the cluster based on node load.
Simple and Easy – Consumer-grade technology applied to enterprises while hiding all the complexity. As my colleague Michael Webster says it best…
