Before you deploy Veritas Resiliency Platform, you should plan how to scale the deployment for efficiency and fault tolerance.

The recommended minimum deployment for disaster recovery to premises data center would be four virtual appliances: a Resiliency Manager and Infrastructure Management Servers (IMS) in the production data center and a Resiliency Manager and IMS in the recovery data center.

The recommended minimum deployment for disaster recovery to cloud data center would be three virtual appliances: an IMS in the production data center and a Resiliency Manager and IMS in the recovery data center.

The production and recovery data centers do not require a one-on-one mapping of IMSs. For example, you can have two IMSs in the production data center and one IMS in the recovery data center.

Although a resiliency domain requires only one Resiliency Manager, you can add multiple Resiliency Managers instances to the domain. For example, you can distribute Resiliency Managers geographically for efficiency of local access.

You can add multiple Infrastructure Management Servers (IMS) to a resiliency domain. For example, if there are multiple data centers in different geographical locations to be managed, you configure a separate IMS for each geographical data center location. You can also configure more than one IMS in the same data center.

If you plan to use Resiliency Platform data mover for replication, then additionally you need minimum one Replication Gateway in each data center. Resiliency Platform supports asymmetric pairing of Replication Gateways. This feature facilitates deployment of only the required number of Gateways on each side, based on data transfer rate and technology specific limits. One Gateway on production site can be paired with multiple Gateways on recovery site and vice versa. One Gateway can be paired with up to 16 gateways on the peer site.
