This document references the standards implemented by TriParadigm to ensure
business continuity for all business functions implemented on the AIX
Power 5 architecture. Many of these standards are not specific to the
Power5 architecture but are intended as enterprise wide standards for
all AIX systems.
These standards have been developed over many years of supporting
standalone, high availability, and disaster recovery environments. The
purpose of these standards is to ensure business continuity during
normal system maintenance, planned and unplanned outages, hardware and
software failures, network and communication failures, and/or a disaster
recovery implementation.
A design aspect of these standards is they can be implemented in a
standalone, high availability, or disaster recovery scenario. Recognize
that there are not multiple standards, one for each scenario, there is
one single standard that is portable across all scenario's. This
reduces support and training costs, and increases efficiency,
supportability, recoverability, and availability.
Some of the basic concepts of these standards:
- Business functions are not tied to a specific machine.
- Hardware resources can be shared or distributed among
associated business functions.
- Any system can act as a failover for any other system.
- Any data center can act as a disaster recovery site for any
other data center.
