Built on IBM X-Architecture®, IBM System x™ and IBM BladeCenter® platforms are designed for energy efficiency and feature:
System x
- IBM-designed chipset — featuring eX4 technology, which allows use of energy-efficient components
- Low-power memory — based on Buffer on Board technology with DDR memory (eX4 systems), which can save over 200 watts over competitive systems using fully buffered DIMMs
- Low-power processor options — select servers such as System x3550 and System x3650 utilize a 50-watt Intel® Xeon® quad-core processor vs. 80 watt
- Smaller hard drives — 2.5 inch drives consume up to 40 percent less power than 3.5-inch drives1
- Smaller, more efficient power supplies — are over 90 percent efficiency in converting AC wall current to DC power
- Innovative Calibrated Vectored Cooling™ — optimizes air intake, fan placement and zone cooling technologies to maximize the air flow inside the server for optimal cooling efficiency
BladeCenter
- Better efficiency than rack servers — for like configurations, IBM BladeCenter can save up to 35 percent on power over 1U servers2
- Low-power processor options — HS21 models are available using 35, 40 or 50-watt Intel Xeon processors. LS21 and LS41 blades use 68-watt AMD™ Opteron™ processors
- Solid state hard drives — use up to 87 percent less power and heat than mechanical
hard drives3
- Integrated 10Gb Ethernet switch — which can be more than 95 percent energy efficient than external switch offerings4
- Innovative Calibrated Vectored Cooling — optimizes air intake, fan placement and zone cooling technologies to maximize the air flow inside the server for optimal cooling efficiency

2 Based on IBM power engineering test data. Numbers are average worst case for P6 Burn exerciser program. Like Intel configurations tested in IBM lab. Blade power is average power of total chassis solution.
3 Solid state drives are 1-2W devices. Mechanical hard drives are 9W devices. 9-1 = 8.8 divided by 9 = .88. Rounded down to 87 percent to account for between 1 and 2W.
4 Based on integrated BladeCenter BNT L2/3 10Gb Ethernet per-port power consumption of 3.1W and external Cisco Catalyst 6500 L2/3 10Gb Ethernet per-port power consumption = 94.3. 3.1/94.3 = 3.3. 100-3.3 = 96.7% savings.
