Annex A 8.14
Redundancy of information processing facilities
Information processing facilities are implemented with sufficient redundancy to meet availability requirements.
What an assessor looks for
Show that redundancy matches stated availability requirements and that failover has been exercised rather than assumed.
Where it usually fails
Redundant infrastructure exists and failover has never been tested, or shares a dependency that makes it not redundant.
