Instances and high availability

A high availability pair is a deployment option that

  • uses two instances on separate chassis to ensure service continuity,

  • allows for multiple high availability pairs to be created from available instances, and

  • permits standalone instances to exist alongside high availability pairs within the same chassis.

You can use High Availability using an instance on 2 separate chassis; for example, if you have 2 chassis, each with 10 instances, you can create 10 High Availability pairs. You can also have standalone instances on the same chassis as High Availability instances. For more information about the requirements, refer to Requirements and prerequisites for instances.
