Active/Standby Example - Compaq ProLiant 1600 Administrator's Manual

Designing the Compaq ProLiant Clusters HA/F100 and HA/F200 2-7
Example – Database/Standby Server
An example business scenario describes a mail order business whose
competitive edge is quick product delivery. If the product is not delivered on
time, the order is void and the sale is terminated. The business uses a single
server to perform queries and calculations on order entry information,
translating sales orders into packaging and distribution instructions for the
warehouse. With an estimated downtime cost of $1,000/hour, the company
determines that the cost of a standby server is justified.
This mission-critical (active) server is clustered with a standby server. If the
active server encounters a failure, this critical application and all its resources
fail over to the standby server, which validates the database and brings it
online. The standby server now becomes active and the application executes at
an acceptable level of performance.
