Expanding a Nutanix Cluster

Number two in the video series……

One of the major appeals of Nutanix is pay as you grow economics. Start small and grow large, no forklift upgrades and having to forecast what your growth will be over the next ‘N’ years. Once you have your initial three node cluster, you can expand out your cluster at any time simply and non disruptively via Prism, you can even mix model types too to run different workloads in the same cluster. 

As you will have seen from the last video (if you haven’t it can be found here), foundation is now CVM based, therefore you can image nodes at the same time you expand out a cluster. Foundation will look at the baseline of the cluster (AOS version ‘X’ and Hypervisor version ‘Y’) and allow you to image a factory configured node to the same settings as your cluster and immediately add the capacity (storage and compute) to that cluster. This is the same regardless of adding a node or a block….

Here’s a video (sped up again) to show the process:
