# Global Command Center

A CommCell environment is a logical grouping of Commvault software components designed to protect, move, store, and manage data. Each CommCell environment comprises a CommServe hosting server, one or more MediaAgents, and clients. For more information, see the CommCell Environment Overview.

Organizations often operate multiple CommCell environments, a setup called a multi-CommCell environment. To centrally manage these environments, you can register various Service CommCells with a single Primary CommCell (Global CommCell), which then functions as the Global Command Center.

In this architecture:

- The Primary CommCell is the Global Command Center, providing a centralized interface.

- The additional CommCell environments are the Service CommCells.

## How the Global Command Center Works

The Global Command Center supports two main management flows:

- Aggregated management: The Global Command Center displays information from registered Service CommCells in one place. For example, dashboards, jobs, alerts, reports, and entity lists show data from the Service CommCells that the user has permission to view. For this flow, the Global Web Server must be able to reach the Command Center URL for each Service CommCell.

- Active Management and blueprints: Active Management lets you create global configurations, such as blueprints, and apply them to multiple Service CommCells. For this flow, the Service CommCell Web Servers must be able to connect to the Global Hub Service. The Global Web Server, Global Configuration Manager, and Hub Service must also be able to communicate with each other.

These flows use different network paths. If aggregated data appears but Active Management or blueprint actions do not work, verify the Global Configuration Manager and Hub Service configuration in addition to the Service CommCell Command Center URLs.

This setup enables administrators to:

- Seamlessly switch between different Service CommCell views using the Command Center.

- From a single interface, view and manage aggregated data, such as job activity, alerts, and capacity usage, across all connected Service CommCells.

- Create blueprints that serve as templates to standardize and deploy configurations or entities, such as policies, alerts, or settings, across multiple Service CommCells.
