Turbonomic Top 10 Features: Cluster Capacity
We will start by selecting “Cluster Capacity” from the Dashboard fly out in your Turbonomic instance. The top left panel of the Cluster Capacity Dashboard will provide a summary of all VMs, physical machines and datastores in each of your clusters. The “Headroom VMs” column to the far right shows the available capacity in your clusters, in other words, how many more VMs you can add and still maintain application performance.
Running a set number of Capacity Plans each night, Turbonomic calculates this headroom number by considering the full range of resource utilization and workload placement for each cluster, without having to add new hardware.
We can select a specific cluster if we want to take a closer look at it’s available capacity. The panel on the right-hand side will show us a summary of resources for this cluster, as they are currently utilized. You will see details about total and peak utilization, High Availability capacity, VM allocation for hosts, VMs and datastores, as well as total used capacity, free space and utilization percentages.
In the bottom left panel, you will see the current number of VMs per host in the selected cluster, in dark green, as well as the number of VMs per host if you were to maximize headroom, in light green. You can also view this information per datastore.
Finally, the bottom right panel is a visual representation of available headroom in the selected cluster. The dark green portion of the circle represents the total number of VMs currently running, while the light green portion represents how many VMs could be added on the existing infrastructure.
To view this information for a different cluster, simply return to the top left panel and select a new cluster.
