4.7 Disaster Recovery Design
This section describes an example disaster recovery design, adding functionality to the existing data center design. Within any disaster recovery design, external factors can drive potential Recovery Point Objective (RPO) and Recovery Time Objectives (RTOs) that the customers can achieve. This includes the following key considerations:
• Latency between the end customer and provider data centers.
• Bandwidth available between the end customer and provider data centers.
• Data change rate of protected virtual machines.
• Complexity of protection groups and recovery plan configuration in Site Recovery Manager.
It is important to understand this before defining a service level agreement for RPO and RTO.
