Go to Advanced > Hardware Tiers.
Click New or Edit, as needed.
Your Hardware Tier’s CPU, memory, and GPU requests must not exceed the available resources of the machines in the target node pool after accounting for overhead. If you need more resources than are available on existing nodes, you might have to add a new node pool with different specifications. This might mean adding individual nodes to a static cluster, or configuring new auto-scaling components that provision new nodes with the required specifications and labels.
