What is High Availability
High Availability is an automated process for minimizing business
function downtime associated with planned or unplanned outages.
Typically utilizes replicated hardware platforms to eliminate single
points of failure. The business function fail-over normally occurs
between two or more physical frames within the same data center using a
single shared storage system.
- Elimination of single points of failure (SPOF's) are a necessary part of HA.
- The goal is to minimize downtime for business functions, not systems.
- This is NOT non-stop computing, downtime will be experienced during fail over.
