Building Disaster Recovery Serviceguard Solutions Using Continentalclusters A.08.00

6 Configuring complex workloads in a Continentalclusters
environment using SADTA
Site Aware Disaster Tolerant Architecture (SADTA) enables automatic recovery of an entire
application stack that is protected using physical data replication. The application stack can be
packaged using mulit-node packages and failover packages with dependencies among them.
SADTA also provides a single interface for manual failover of all the packages configured for an
application stack.

This section lists and describes the procedures for configuring a complex workload in
Continentalclusters using SADTA.
To configure a complex workload in Continentalclusters:
1. Set up the replication between the arrays in the primary cluster and the recovery cluster.
2. Configure a primary cluster with a single site defined in the Serviceguard cluster configuration
file.
3. Configure a recovery cluster with a single site defined in the Serviceguard cluster configuration
file.
4. Set up the complex workload in the primary cluster.
