Question
-
Does anyone have any experience with using VMware's SRM to failover an Enterprise CA to a new VMware host at a different site for the purposes of disaster recovery?
A customer I am working with is keen to virtualise their entire Windows estate. While I have suggested running two Enterprise CAs, one in each data centre, the customer is unconvinced of the need for the second CA and wants SRM to manage availability.
I don't have much experience with VMware and its associated technologies and am concerned about the risk of data corruption, particularly to the CA database, when SRM is involved.
Has anyone used this approach to provide availability for an Enterprise CA? Would it even be viewed as a supported configuration by Microsoft?

Hi Steven,
If your purpose is failover, you need to configure the CA as a failover cluster. For more information, please refer to:

Another option is making an effective disaster recovery plan to ensure that, in the event of failure of the server hosting Certificate Services, you can recover in a timely manner. However, this is not failover, so you have to complete the restore process to a new server in a timely manner with little effect on your organization. For more information, please refer to
Disaster Recovery Procedures for Active Directory Certificate Services (ADCS)
Regarding the VMware Site Recovery Manager, please understand that I’m not familiar with it and you may contract VMware support.

Yes. The only way to do failover is to configure the CA as a failover cluster.

why don't use two enterprise CAs? that should be an easy method.

Hi, Bruce,
Thanks for the reply. Are you stating that CA availabilty is only supported if accomplished through an active/passive cluster? If this is the case, that's fine, I can pursue my CA in each data centre option. For future reference, can I assume that providing availability for a CA server using VMware Site Recovery Manager is an unsupported configuration?
