The following diagram depicts the Disaster Recovery and High
Availability scenario for a Tier 1 service agreement level, as
implemented by
VLPAR®
automated deployment. Under this scenario, four(4) nodes are created
across two datacenters, two nodes in each datacenter.
In this scenario, both datacenters are considered to be running
production business functions. These functions normally run on a single
node in one of the datacenters, with a hot-standby node providing high
availability fail-over capabilities. Periodically, for maintenance and
disaster recovery testing, the business function load is shifted from
one datacenter to the other. Once the business functions are running in
the other datacenter, it is not failed-back until the next scheduled
maintenance or an unscheduled outage to the datacenter occurs.
