This document gives the minimum CPU, RAM, and storage requirements to create an admin cluster and a user cluster on a single ESXi host.
The requirements given here are suitable for a proof-of-concept demonstration. For production hardware requirements, see CPU, RAM, and storage requirements.
Minimum CPU, RAM and storage requirements
Suppose you want an installation that has the following elements:
An admin workstation
Seesaw load balancing
An admin cluster that has:
- One Admin cluster control-plane node
- Two admin cluster add-on nodes
- One user-cluster control-plane node
- Fleet registration enabled
- Anti-affinity groups disabled
A user cluster that has:
- Three worker nodes
- Fleet registration enabled
- Anti-affinity groups disabled
Note that there is only one control-plane node for the user cluster. This means that the user cluster does not have a high-availability control plane.
Then these are the minimum resource requirements:
- 8 physical CPUs @ 2.7GHz with hyperthreading enabled
- 40 GiB RAM
- 450 GiB of storage
Add Cloud Logging and Cloud Monitoring
If you want to add Cloud Logging and Cloud Monitoring to the installation described in the preceding section, you need an additional 20 GiB of storage. So the minimum resource requirements would be:
- 8 physical CPUs @ 2.7GHz with hyperthreading enabled
- 40 GiB RAM
- 470 GiB of storage
Example host and datastore
