Service Level Agreement: Tier 4

The following diagram depicts the Disaster Recovery and High Availability scenario for a Tier 4 service agreement level(SLA), as implemented by VLPAR^tm automated deployment. Under this scenario, two(2) nodes are created in an HACMP cluster within a single datacenter.

In this scenario, a two(2) node one-way cascading HACMP cluster is running in the production datacenter. The business functions normally run on a single node in the cluster, with a hot-standby node providing high availability fail-over capabilities. In the event of a hardware failure, the business functions are failed-over to the hot-standby node. In the event of a disaster, no pre-built provisions exist.
