Server consolidation and high availability
Server consolidation is the process of combining software from two or more servers on a single, more powerful server to make server maintenance easier and thus lower the total cost of ownership.
One way of consolidating servers is logical partitioning, where one server is configured to act like several separate physical servers. The IBM® LPAR products for AIX® are one example.
If you plan to implement logical partitioning in a highly available environment, you must take into account the distribution of the FileNet P8 components across the servers. If a single physical failure on a consolidated server can take down two or more logical servers running in parallel on that server, then redundant servers for a server farm or server cluster should not both reside on that consolidated server unless the risk of that failure is deemed to be exceptionally low. Otherwise, a single point of failure can take down an entire farm or cluster, violating a central premise for high availability.
