You must set up the storage and network of your vCenter Server cluster configurations to meet certain requirements so that you can install Application Services in vCloud Director or vSphere.

Familiarize yourself with the procedures for creating vSphere 5.0, 5.1 or 5.5 resource pools and vCenter Server clusters that have DRS enabled. See the vSphere documentation center.

Verify that you have one or more hosts running vSphere ESXi 5.0, 5.1, or 5.5.

Verify that you have a vCenter Server cluster with DRS enabled.

Verify that you have the NTP client running on each of the vSphere ESXi hosts in your vCenter Server installation.

Synchronize the time on the host on which Application Services is deployed and on the hosts on which virtual machines are to be deployed. If the time is not synchronized, the Application Services server might experience problems when communicating with the provisioned virtual machines.

To synchronize the time on the hosts, set an NTP server to the Configuring Time option for each ESXi host underlying the vCloud Director system.


Create a cluster with DRS enabled.


Check the configuration settings for datastore and network requirements.



Multiple hosts in a cluster

Verify that all of the hosts have at least one shared datastore, for example, shared LUN, NFS, and so on.

Verify that all of the hosts in the cluster have connectivity to at least one common network.

To support live virtual machine migration, verify that all of the hosts in the cluster are identical.

Network or SAN storage

Verify that your host has shared storage.

Although vCloud Director and Application Services can use local storage, shared storage ensures future scalability.

Verify that the host has at least one network.

For vSphere, deploy the Application Services appliance. See Deploy the Application Services Appliance in vSphere.

For vCloud Director, configure the vApp settings to install Application Services. See Set Up vCloud Director for Application Services.
