The type of hypervisor connection determines the operation mode for App Volumes.

App Volumes supports three hypervisor connection types.

  • VMware vCenter Server. This is a preferred connection type for mid-to-large environments. This connection type enables the use of VMDK Direct Attached operation mode . When using this connection type, you can assign AppStacks and writable volumes to the virtual machines running on multiple hypervisor hosts.

  • Single ESXi Host. This connection type also enables the use of VMDK Direct Attached Operation Mode, but only for a single ESXi host. Use this connection type for small deployments and proofs of concepts. When using this connection type, you can assign AppStacks and writable volumes to the virtual machines running on a single hypervisor host.

  • VHD In-Guest Services. This connection type disables hypervisor connection and enables the use of VHD In-Guest operation mode. Use this connection type to assign AppStacks and writable volumes either to virtual machines running on an unsupported third-party hypervisor or to the physical computers.
