When deploying the OVA file for Advanced Threat Protection (ATP), the ESX server fails to deploy the OVA. Instead the ESX host logs an error.
The disk capacity specified is greater than the amount available on the datastore. Click Cancel to return to the previous page. If the datastore capacity has been increased since the last update, click OK to continue deploying the OVF template.
Multiple possible causes...
If your ESXi server is using VMFS-2, then set block size to 4MB or greater.
If you are using a filesystem later than VMFS-2, then set block size to 8MB or greater.
If the resource pool or VMWare server has less than 500GB available, add disk capacity resources to the ESX Server or resource pool to permit deployment of the OVA for ATP 2.0 with thick disk provisioning.
If the resource pool or VMWare server has less than 100GB available, add disk capacity resources to the ESX server or resource pool to permit deployment of the OVA for ATP 1.0 with thick disk provisioning.
