Trend Micro Deep Security, 2 vCenters: one or two Deep Security Managers?

Hi all,

in my environment I have two vCenter 5.1 servers, one for Production in a prod domain and one for Test in a test domain. The production environment is protected with Site Recovery Manager and can be "failed over" to the second vCenter (the Test environment). I need some advise about implementing Trend Micro Deep Security 8.

Should I install two Deep Security Managers, one on each vCenter or install one Deep Security Manager servicing two vCenters and protect it with SRM? What are the advantages and disadvantages of both options? Are there other options?

Regards,

Nelcon.
