Backup vSphere Hypervisor 5.1 with Backup Exec?

Hi,

Our department is converting to an virtual environment. We have two servers, both IBM System X 3650 M2, running vSphere hypervisor 5.1 (free license). We also have a contract with Symantec and use Backup Exec as our backup solutions.

Being new to vSphere, I would like to know what packages do I need from Symantec, and if I need to buy anything from VMWare, to be able to use Backup Exec to backup the guests on our servers.

Thanks.
