Abstract: Availability needs of more and more datacenter administrators require their TPC environment to be set up in a redundant way.
To achieve this goal, a SAN-boot based redundancy concept was developed to allow fast switching of server hardware. The central TPC server (including database, etc.) is equipped with a Fiber Channel HBA to allow mirroring internal hard disks into the SAN infrastructure. Using traditional disaster recovery techniques such as subsystem mirroring, availability of the data can then be assured across sites.
This paper describes an exemplary realization of this concept, as implemented for multiple European clients. It serves the purpose of acting as a blueprint for developing tailored operational documents and guidelines.
