Virtualization: Optimized Power and Cooling to Maximize Benefits
Virtualization is an undisputed leap forward in data center evolution - it saves energy, it increases computing throughput, it frees up floor space, and it facilitates load migration and disaster recovery. With these benefits though, come new challenges to the power and cooling infrastructure. While an upgrade of power and cooling systems is not necessarily required to make virtualization "work", the greatest benefits from virtualization will be realized with power and cooling that responds to these challenges.
Challenges such as:
- Dynamic and migrating high-density loads
- Underloading of power/ cooling systems
- The need to ensure that capacity meets demand at the row, rack and server level
Although these challenges aren't necessarily exclusive to a virtualized data center, the combined simultaneous effects of virtualization are focusing attention on them with a new urgency.
This paper will describe each type of power and cooling solution that best handles each of these challenges and approaches them in the context of a virtualized environment.
