Thomas's business critical production software application needed a cost-effective failsafe solution in place to make sure that it would be accessible to users immediately and efficiently. Should the application go down, it would be costly to Thomas financially, and would damage their credibility in the eyes of their clients.

Implement a "cold-standby/fail-over" solution for the application running on the Sun E250 server, enabling it to be switched over to the second Sun E250 server in the case of failure.

Sengen also needed to educate and prepare Thomas system administrators to operate the solution after the end of the engagement.

Installed host information from the first server onto the second server using a Programmable Read Only Memory (PROM), provided by Sun.

Documented technical specifications and operational procedures throughout the engagement.

Created detailed documentation and trained the client staff on procedures for switching to the cold-standby server in case of failure. Sengen also educated and trained the Thomas staff on the need for, and process of, creating the backups required to ensure that no information was lost during the switch to the cold-standby.

Sengen's solution cut the potential down time of the server from more than a day to less than half an hour.

Provided procedure documents and training for switching between the primary and backup servers so that Thomas personnel could monitor and fix any problems after the end of the engagement.
