Supported Configurations and Sizing Guideline

IMPORTANT

1. Only the above-listed combinations of RAM and Disk are supported, more will be added in future releases.

2. The 1 GB RAM and 60 GB Disk minimal, default profile is not recommended for production. It is recommended for

demos and proof-of-concepts.

3. The above sizing recommendations are based on an average mix of various traffic types; the actual sizing will depend on

the traffic mix in a given deployment scenario.
