# Determining the Network Topology for Linux CommServe Bare Metal

Determining the network topology is a crucial first step that can affect nearly every part of the Linux CommServe Bare Metal deployment in your environment.

The Linux CommServe Bare Metal image software leverages several technologies that are critically dependent on a fast and stable network connection. Due to that, there are guidelines on how the network should be configured to ensure that the appliance is stable and meets the performance expectations.

Important

Several pre-defined topologies have been validated and built into the software. These validated topologies are explained below.

If the network topology in your environment is not listed here, or if you are not sure of the topology that is required for your environment, contact your Commvault representative for assistance.

Answering the following questions will help to determine a recommended topology:

- Do you require network redundancy?

- Do you have a dedicated non-routable backup network?

- Do you require the appliance to be connected to multiple vLANs?

Use the following selection guide to determine the topology required for your environment:

Require Network Redundancy | Have dedicated non-routable backup network | Require multiple VLANs connected to the appliance | Recommended Topology
--- | --- | --- | ---
No | No | No | Basic topology
Yes | No | No | Bonded topology
