Deploy Commvault Grid Using Bonded Topology with Management Network

HyperScale X nodes can be deployed using bonded data protection and storage pool interfaces, along with a dedicated management interface.

In this topology:

Bonded interfaces are used for CommServe Registration and Storage Pool communication.
A separate 1 GbE interface is used for the Management network.
The management interface is used for management communication, such as connecting to the CommServe server and accessing DNS services.
The management interface cannot be configured with bonding.

The following bonding modes are supported:

Mode 1 (Active-Backup), which provides fault tolerance through a standby interface.
Mode 4 (802.3ad), also known as Link Aggregation Control Protocol (LACP), which provides network redundancy and load distribution.

Use this deployment method when the data protection network is isolated or non-routable and a separate management network is required for administrative communication.

Use this procedure to deploy the HyperScale X software using the Hyperscale ISO 3.2312 or higher version.

Note

During the setup process, ensure that the following passwords do not contain the special characters ', ", /, ~, or \:
- Root password
- Restricted shell user (cvbackupadmin) password
- CommServe connection password
When deployment is complete:
- Password-based root access is disabled.
- Firewall protection is enabled.
- Ransomware protection is enabled automatically.

Before You Begin

Select the resiliency mode relevant to your environment. For guidance, see Selecting Resiliencey.

If you plan to connect to an existing CommServe server, gather the following information before you begin:

The fully qualified domain name (FQDN) of the CommServe server based on the endpoint type used in your deployment.

Endpoint Type	Example	Applicable to SaaS Deployment
CommServe FQDN Registration	`test.commvault.com`	No
Backup Gateway (default port)	`test.eastus2.cloudapp.azure.com`	Yes
Backup Gateway (non-default port)	`test.eastus2.cloudapp.azure.com:443`	Yes
Registration URL (Metrics)	`https://metrics.metallic.io`	Yes
Registration URL (CommServe)	`https://test.commvault.com`	No

The credentials of an administrative user.
Confirmation that TCP ports 8400 and 443 are open between the nodes and the CommServe server.

Verify the requirements needed for setting up the Bonded Topology With Management Network.

Tip

Keep the network names and IP addresses listed in the Network Requirements section of Bonded Topology With Management Network handy before you start the configuration. This will help you accurately enter the required values during deployment.
Verify that the network switches are configured for the selected bonding mode.
- For Active-Backup deployments, verify that the required interfaces are connected and operational.
- For LACP deployments, verify that the required port-channels have been created for both the data protection and storage pool networks.
Verify that the same bonding mode will be used for both the data protection and storage pool interfaces.
Verify that the management network is routable and can communicate with the required infrastructure services, including DNS and the CommServe server.
The Managed Service Provider (MSP) administrator or the tenant administrator performing the installation must obtain the authorization code.

For instructions on activating the authorization code, see User Administration and Security.
