Reduce cooling requirements & power consumption with IBM POWER6™IBM experienced a significant technical breakthrough in its development of the POWER6 processor, finally solving the power leakage issues commonly associated with high frequency. This new chip drops to 35% of its usual power consumption when idle, and even when active, acts to save costs. By doubling performance without increasing power consumption, power costs are effectively cut in half.
Utilize POWER6’s enhanced virtualization features enable maximum system utilization, and with other capabilities like LPM (Live Partition Mobility), consolidation projects can be performed without disruption. This simplifies the process of reallocating active workloads to POWER6 systems, potentially enabling the powering down of unused servers.
In addition, the new Power Systems from IBM feature increased capabilities for energy management. Control power and cooling needs with EnergyScale™ technology, which can monitor power and thermal utilization, and enabling power management features.
EnergyScale continuously monitors power usage within systems, providing predictability and insight into the power consumption trends within servers. With this technology, loads can be managed to optimize power usage based on cost during the time of day, anomalies in power usage can be identified, and appropriate power caps can be determined if so desired.
Power Saver Mode reduces the voltage and frequency usage of a system be a fixed percentage. With management tools, Power Saver Mode can be manually enabled (such as at night), and disabled as needed, or a customized script can be written into the system to enable and disable Power Saver Mode.
Limits on power usage can be enabled with the Power Capping feature. This enables data center manages to provision exactly what the system needs, not provision it based on the UL rating, which provides power requirements based on a worst-case scenario with a fully-configured system running at peak usage.
If workloads are not utilizing the power of a particular processor, the Power system can put that CPU into Nap mode, which stops processor execution and clocks-off most of the circuits. In addition to the power savings, the temperature falls, further reducing leakage of static power.
Power Systems automatically power off unused PCI adapter slots that are empty, not assigned to a partition, or if the partition assigned to the slot is powered off, further gaining energy efficiency by approximately 14 watts per unpowered slot.
