Active power management is the secret to cost-efficient data centre computing and is a feature that must be built into every server operation, French computing services company Bull has said.
It has revealed plans to market energy-saving software tools from Cassatt Corp that will automatically power off unused servers, based on policies set by a data centre administrator.
Dynamic control, repurposing, and power management of servers can result in consumption being reduced by a factor of at least 30% for business operations workloads. Other workloads, such as application development, may benefit from even larger factors of up to 50%, the companies have claimed.
Gartner takes the line that the ability to use virtualisation for application and virtual machine migration to shift workloads to lower utilisation periods is a key aspect of energy efficiency in the data centre.
This calls for automated power down of servers and, subsequently, power up and workload moves.
Bull is pushing the idea of greener server farms as part of its year-long energy efficiency, Bio Data Center initiative. Bull said it will distribute the Cassatt software on its own NovaScale and Escala servers, and will provide consulting services to help organisations assess the current status and define optimisation plans for their of data centres.
