Prerequisites for OnApp vCenter Integration

Updated for OnApp 5.8 (31st May 2018)

In order to install OnApp's vCenter integration there are a number of requirements that you should be aware of first. 

Hardware / Infrastructure

To use the OnApp for vCenter, you will need to deploy a control panel server that the OnApp software will be installed on.

You simply need to deploy an OnApp Control Panel server with the following specifications:

Minimum

• 4 CPU Cores
• 16GB RAM
• 100GB Disk
• CentOS 6.x minimal x64

Recommended

• 8 CPU Cores
• 32GB RAM
• 250GB Disk
• CentOS 7.x minimal x64

If you wish to build a central template repository, you will need to deploy an additional Template server with the following specifications:

• 4 CPU Cores
• 16GB RAM (32GB+ recommended)
• 100GB Disk (200GB+ recommended)
• CentOS 6.x minimal x64

For network connectivity, it is recommended that one interface is used for public traffic (this will need to access the OnApp licensing server) and the other interface has a connection to the same network as your vCD management traffic. If you prefer to have only one interface and use NAT, that is fine as well.

vCenter Requirements

If you are looking to run VMware ESXi servers through OnApp, then you will require an external installation of vCenter. These can be installed on virtual servers, if necessary, but should not be hosted inside OnApp.

The OnApp Control Panel server communicates with vCenter over the OnApp management network.

The following are the requirements for VMware integration with OnApp Control Panel:

• VMware vCenter data centre with one or more clusters.
• Each ESXi server & cluster must have access to all storage & network resources in the data centre.
• ESXi servers must already be added to the cluster inside of vCenter.
• At least one data store on the ESXi servers is required for the virtual server provisioning.
• Ensure that the CP server has access to the vCenter and all of the ESXi servers in the cluster used by CP on the management network.
