  ■ Only 1 VDP appliance can be deployed per ESXi host.
  ■ Each VDP appliance supports backing up 100 VMs.
  ■ Each VDP Advanced appliance supports backing up 400 VMs.
  ■ Each VDP appliance can back up a maximum of 8 VMs simultaneously.
  ■ VDP appliances operate independently of each other.
  ■ Independent virtual disks are not supported.
  ■ Physical compatibility mode RDMs are not supported
  ■ Independent virtual compatibility mode RDMs are not supported
  ■ VMs larger than 2TB that run Windows operating systems are not supported for

What are requirements for deploying VDP

Answer 16

• DNS A and PTR records should be created for each VDP appliance.
  ■ Ensure that DNS A and PTR records for vCenter Server are present in the environment.
  ■ VDP appliances obtain their time through VMware Tools, so ESXi hosts and vCenter
  Server should have the same time source and be configured correctly.
