Disaster Recovery
Business function recovery between geographically separated data
centers using a storage replication system between the data
centers.
The output of disaster recovery planning is a disaster recovery
project plan.
The goal is to minimize downtime for business functions, not
systems.
Business function recovery times and maximum allowable data loss
is specified during the business impact analysis.
High Availability
Business function fail over between two or more physical frames within the same data center using a single shared storage location.
Elimination of single points of failure (SPOF's) are a necessary part of HA.
The goal is to minimize downtime for business functions, not computer systems.
This is NOT non-stop computing, downtime will be experienced during fail over.
