The IBM energy management portfolio tackles the challenge to increase power and thermal efficiency and reduce costs on three levels: Inside the system. All IBM System x™ and BladeCenter® servers start with Calibrated Vectored Cooling technology, which allows dual paths of air to each component, improving uptime and longevity, and reducing wasteful air movement and heat generation. Coupled with more-energy-efficient power supplies, IBM BladeCenter and System x servers can generate less heat in the critical AC-to-DC power conversion than many alternative systems from the competition. In the rack. IBM System x servers are designed to work at full density in a well-planned rack solution. They are also designed to operate at extended temperature ranges to keep the system up and running — even in extreme temperature and failure conditions. IBM rack solutions are engineered to optimize air flow and prevent undesirable recirculation within the rack, meaning your servers can run in optimal temperature conditions. With IBM BladeCenter. Less power per processor means more processing capacity per kilowatt. BladeCenter servers, with IBM mainframe-inspired technology, can enable you to pack more processors into the same power and cooling envelope as well as better utilize your floor space and "right size" your data-center design. Simply put, the IBM BladeCenter runs cooler to deliver greater reliability and uses as much as 22 to 37 percent less energy than HP p-Class blades. In the room with servers and storage. Understanding the data center is key to a healthy server environment. If your room cannot handle the kind of density your business requires, then look to smart rack-level heat solutions like the super-efficient IBM Rear Door Heat eXchanger. The water-cooled door is designed to dissipate heat generated from the back of your rack to reduce the overall room temperature.
IBM System x and IBM BladeCenter servers can be easier and less costly to cool than competitive servers. The following solution building blocks can help enable high reliability and help you achieve real cost savings: The IBM PowerExecutive™ solution building block can help you optimize existing computing resources by using them at levels close to the cooling and power limits of your data center, thus improving workload throughput performance. IBM PowerExecutive is a standard building block in selected IBM System x and BladeCenter servers. IBM PowerExecutive enables you to measure, track and control server power consumption. The graphical user interface can help you understand how energy is used within the data center, and provides the insight required to optimize your servers and their workloads for the best performance. IBM PowerExecutive is an integrated hardware, software and firmware solution building block. PowerExecutive manages energy consumption, allowing you to control electricity costs for your business. The PowerExecutive application, a software extension to IBM Director 5.1x (or later), monitors and displays the collected power measurement data for individual servers. Additionally, it provides analysis of long-term power trends for all servers in the data center with IBM PowerExecutive installed. This assists in the timely planning of costly facilities upgrades so they can be implemented before server power and temperature grow beyond the capacity of the data center. More accurate power-consumption predictions can help enable you to:
| | Reduce the infrastructure required for redundancy. |
| | Allow more servers to be installed on smaller power feeds. |
| | Lower overall data center capital and operation costs. |
The IBM Rear Door Heat eXchanger is designed to remove heat generated from the back of your computer systems before it enters the room. The efficient IBM Rear Door Heat eXchanger, which takes heat from the rack with water, can substantially reduce the heat load coming from any IBM enterprise rack. Advantages include:
| | No fans or electricity needed, alleviating the chance for mechanical fan failure. |
| | Passive design, allowing systems to air-cool without opening or removing the door. |
| | Condensation prevention. |
| | Attaches to the back of the rack (adds five inches), and does not change the footprint of the racking. |
IBM Calibrated Vectored Cooling technology optimizes the path of cooled air flow through the system, directing cool air to the areas that need it, and blocking hot air from entering critical areas of the system. This allows your systems to run cooler and use less power. The IBM Power Configurator tool can help provide better sizing information for your solutions. The Power Configurator allows you to estimate building and data-center electrical costs before you make a purchase. By allowing total customer control of all server power options, the Power Configurator gives an accurate display of required data-center electrical requirements for servers. Simply select your rack-mounted server or blade and then configure your desired options. Power Configurator will then tell you the electrical wiring assumptions for your data center. Take the power challenge using the IBM Power Calculator, and discover the energy savings a System x or BladeCenter server can bring to your business.
