Reduced costs of power / green benefit
Power saving reduces consumption.
To help IT managers go greener more quickly and easily, Microsoft has included new power management updates in Windows Server 2008 R2.
CPU Core Parking reduces consumption according to workload, so you’re not paying for constant power usage during light system use – which is also an inherent benefit of virtualisation.
When Core Parking is enabled, Windows Server 2008 R2 will constantly monitor the various workloads running across multi-core server systems. If certain processor cores are under-utilized, or not needed, Core Parking can put them into sleep mode, thus saving significant power.
If workloads suddenly increase, R2 can spin up dormant cores in a matter of milliseconds. So a server with 64 logical cores can drop to just a 4-core machine during low-utilization times and rev back up to full CPU power as soon as workloads increase.
In addition, Windows Server 2008 R2 enables administrators to design active power policies that can cause servers to ‘throttle-down’ during off-hours by using DMTF-compliant, remote management interfaces.
