Energy Efficiency - IBM x3850 X6 Planning And Implementation Manual

IBM FlashCache Storage Accelerator:
IBM FlashCache Storage Accelerator is an all-in-one flash-caching product that leverages
the speed, management, capacity, and breadth of the IBM High IOPS adapters and
qualified SSDs and integrates them into a high speed server-side caching service that
seamlessly accelerates the most important data with little or minimal IT overhead in both
physical and virtual servers.
These new technologies will allow IBM X6 servers to deliver break-through performance for
targeted workloads by offering significantly lower latency and higher performance compared
to traditional solid-state drives.

1.6 Energy efficiency

The x3850 X6 and x3950 X6 offer the following energy-efficiency features to save energy,
reduce operational costs, increase energy availability, and contribute to the green
environment:
Energy-efficient electronic components help lower operational costs.
Highly efficient 900 W AC and 1400 W AC power supplies have 80 PLUS Platinum
certification.
Intel Xeon processor E7-4800/8800 v2 product families offer significantly better
performance over the previous generation while fitting into the same thermal design power
(TDP) limits.
Intel Intelligent Power Capability powers individual processor elements on and off as
needed, to reduce power draw.
Low-voltage Intel Xeon processors draw less energy to satisfy the demands of power and
thermally constrained data centers and telecommunication environments.
Low-voltage 1.35 V DDR3 memory RDIMMs consume 15% less energy compared to 1.5
V DDR3 RDIMMs.
Solid state drives (SSDs) consume as much as 80% less power than traditional spinning
2.5-inch HDDs.
The server uses hexagonal ventilation holes, which is a part of IBM Calibrated Vectored
Cooling™ technology. Hexagonal holes can be grouped more densely than round holes,
providing more efficient airflow through the system.
IBM Systems Director Active Energy Manager™ provides advanced data center power
notification and management to help achieve lower heat output and reduced cooling
needs.
