Data center topologies for mission-critical business systems

In this paper we examine the ways in which data center topology choices affect mission-critical business system availability and we propose a methodology for ensuring business resilience by assessing the risks to the mission-critical business systems and then designing a data center topology to mitigate these risks. This methodology is based on the IBM Business Resilience Framework, a framework that accounts for a wide range of concerns, from data center facilities to the business strategy and vision.
