Scenario

Pick a starter lab or build your own. Resource values are based on the CML sizing data for this calculator.

State not saved yet

Size a specific lab from topology YAML

Upload a CML topology file to populate this calculator with the node counts from that lab. The current scenario will be replaced by sizing for the uploaded topology.

The file is parsed entirely in memory, used only to size the recognized nodes in this lab, then discarded immediately.

Starter labs

Preset ideas inspired by common CML sample-lab patterns and community topologies.

Totals

Size one lab, then multiply by concurrent labs to estimate total deployment requirements.

Node catalog

Build your lab as a short list of selected node types. Unknown disk values stay out of the disk total.

Custom images

For images that are not listed in the standard node catalog.
