# Adding Data Source

To collect information about your virtual infrastructure and track the efficiency of VM data protection, you must configure connections to VMware vSphere, VMware Cloud Director, Microsoft Hyper-V virtual management servers and Veeam Backup for Microsoft 365 and Veeam Backup & Replication servers in Veeam ONE. Configured connection settings are automatically propagated to all Veeam ONE components.

You can connect the following types of servers:

- [Veeam Backup & Replication](backup_server_connect.md)
- [Veeam Backup for Microsoft 365](vbo_server_connect.md)
- [VMware vSphere](vsphere_server_connect.md)
- [VMware Cloud Director](vcloud_server_connect.md)
- [Microsoft Hyper-V](hyperv_server_connect.md)

## Before You Begin

Before you configure server connections, check these requirements:

- Supported versions of virtual platforms
- Supported versions and editions of Veeam Backup & Replication and Veeam Backup for Microsoft 365
- Requirements to accounts used for collecting data
- Ports that must be open to allow Veeam ONE collect data from connected servers
