# Access Nodes for Hypervisors and VM Groups

An access node manages data protection operations for a hypervisor or a VM group.

Access nodes are servers. You can deploy an access node by adding a server or by adding Commvault software to an existing server.

## Required Packages for Access Nodes

- Access nodes must have the Virtual Server software package installed.

- For an access node to support IntelliSnap, it must have both the Virtual Server software package and the MediaAgent software package installed.

## Access Node Requirements by Hypervisor

- Alibaba Cloud: An Alibaba Cloud instance in the zone to be protected.

- Amazon EC2: An Amazon EC2 instance in the region to be protected.

- Azure: An Azure virtual machine in the region to be protected.

- Azure Local: Virtual Server software package installed on either a standalone Azure Local server or a node within an Azure Local cluster.

- Google Cloud: A Google Cloud instance in the region to be protected.

- Hyper-V: Virtual Server software package installed on either a standalone Hyper-V server or a node within a Hyper-V cluster.

- Nutanix AHV: A virtual machine in the Nutanix cluster.

- OpenStack: An instance in the OpenStack data center.

- Oracle Cloud Infrastructure: An Oracle Cloud Infrastructure instance.

- Oracle VM: A virtual machine hosted on an Oracle VM Server.

- Red Hat Virtualization: A virtual machine in the same RHV data center.

- vCloud Director: A physical machine, or a virtual machine in vCloud or VMware.

- For VMware, the backup server where Commvault is installed is automatically selected as a default proxy. As needed, you can add additional physical servers or VMware VMs and configure them as proxies.

For more information about access node requirements, see the Commvault documentation for the hypervisor.
