High Availability White Papers
High Availability Messaging Solution: Using the AXIGEN Mail Server, Heartbeat and DRBD
Overview In today's business environments, one often hears the term 'High-availability'. Whether a hardware or software solution, the paper aims for redundancy at all levels, so as to maximize the availability of mission-critical services and operations. As always, the hardware redundancy is more costly to achieve. Implementing a certain level of redundancy at the hardware layer is usually over ten times more expensive than obtaining the same redundancy only through the software layer. So whenever possible to substitute high-availability at the hardware level with a similar availability at the software level, one should definitely go ahead with it, given the cost-effectiveness of the solution, and especially if the process does not involve any performance drawbacks.
