vSphere Configuration Requirements
Servers and hosts intended for use with vCloud Director must meet specific configuration requirements.
n
vCenter networks intended for use as vCloud Director external networks or network pools must be
available to all hosts in any cluster intended for vCloud Director to use. Making these networks
available to all hosts in a datacenter simplifies the task of adding new vCenter servers to
vCloud Director.
n
vSphere Distributed Switches must be used for cross-host fencing and network pool allocation.
n
vCenter clusters used with vCloud Director must configure storage DRS with an automation level of
Fully Automated. This configuration requires shared storage attached to all ESXi hosts in a DRS cluster.
vCloud Director can take full advantage of Storage DRS, including support for fast provisioning, with
vCenter 5.1 or later.
n
vCenter servers must trust their hosts. All hosts in all clusters managed by vCloud Director must be
configured to require verified host certificates. In particular, you must determine, compare, and select
matching thumbprints for all hosts. See Configure SSL Settings in the vCenter Server and Host
Management documentation.
vSphere Licensing Requirements
vCloud Director requires the following vSphere licenses:
n
VMware DRS, licensed by vSphere Enterprise and Enterprise Plus.
n
VMware Distributed Switch and dvFilter, licensed by vSphere Enterprise Plus. This license enables
creation and use of vCloud Director isolated networks.
