Network configuration is the first phase of deploying Commvault Grid nodes. During this phase, you configure the network interfaces that will be used for:
- Data protection traffic
- Storage pool communication
- Optional management communication
- VLAN-based traffic segmentation
- Network redundancy and failover
The deployment workflow and configuration screens vary depending on the network topology selected for your environment. Before proceeding, determine the network topology that best meets your operational, resiliency, and segmentation requirements.
Important
Before configuring Commvault Grid nodes, review and select the appropriate network topology.
Cisco Fabric Extenders (FEX) are not recommended for Commvault Grid deployments. Connecting Commvault Grid nodes through a Cisco FEX can introduce performance and stability issues.
Before You Begin
Verify that the following tasks have been completed:
- DNS records have been created and validated.
- Network switches have been configured.
- The required VLANs have been created (if applicable).
- IP addresses have been allocated for all nodes.
- Commvault Grid software version validation has been completed.
- Hardware readiness checks have been completed.
Choose a Deployment Method
Select the deployment procedure that matches the network topology used in your environment.
| Topology | Recommended Use Case |
|---|---|
| Basic Deployment | Small deployments, lab environments, and non-production environments |
| Bonding (Active-Backup or LACP) | Production environments requiring network redundancy |
| Basic Deployment with Management Network | Isolated backup networks that require separate management communication |
| Bonding with Management Network | Production environments requiring both network redundancy and management isolation |
| Tagged VLAN | Environments that use multiple backup VLANs or segmented backup networks |
| Tagged VLAN with Management Network | Segmented backup networks that require separate management communication |
| Tagged VLAN with Bonding | Enterprise environments requiring both VLAN segmentation and network redundancy |
| Tagged VLAN with Bonding and Management Network | Large-scale enterprise deployments requiring segmentation, redundancy, and management isolation |
