HP promotes green blade strategy to build green data center
As national policies increase the requirements for energy conservation and consumption reduction, energy conservation and consumption reduction are becoming the focus of the country and the whole society. The rising proportion of IT energy consumption in all electricity usage has made it one of the main areas where society advocates energy conservation and consumption reduction. As the world's leading IT company and an enterprise with a strong sense of social responsibility, HP actively advocates the concept of "green IT", increases research and development, and launches a series of innovative technologies and products for green IT.
On October 26, HP held a "Green Blade" seminar at the Xiangshan Hotel, introducing HP's new generation data center and new generation blade system BladeSystem c-Class in terms of power supply and cooling. Green innovative technology and environmental protection and energy saving advantages, and launched a complete solution for green data centers.
For a long time, more powerful data center processing capabilities have been our goal. But today, as energy costs are increasing day by day, the other side of the development of processing power is the need to consume more resources. And as server density continues to increase, power requirements also increase accordingly, generating more heat. Server power density has increased tenfold on average over the past decade. According to IDC's forecast, IT procurement costs will be equal to energy costs by 2008. On the other hand, cooling accounts for 60 to 70% of the energy consumption of data centers. Therefore, as energy prices continue to rise, the power supply and cooling problems of data centers have become unavoidable issues for all data centers.
HP has been committed to the research of energy-saving and consumption-reducing technologies for more than ten years, and is committed to innovation at three levels: first, environmental-level energy-saving technology at the data center level; second, for servers, storage and other IT The green design of products at the system level; the third is the research and development of key energy-saving components, such as technological innovation in power supply, refrigeration, fans, etc. Currently, these innovative technologies from HP Labs are leading the green trend in the industry.
At the data center environment level, HP has launched a new dynamic intelligent cooling system to help customers build a new generation of green data centers or transform existing data centers; at the equipment level, HP's new generation of green blade servers The system has become the most critical infrastructure for energy saving in future data centers with innovations in energy intelligent control (Thermal Logic) technology and PARSEC architecture. At the same time, these innovative technologies are reflected in some key energy-saving components, such as Active Cool (active cooling) fans, Dynamic power adjustment technology (DPS, Dynamic Power Saver), etc. HP's green innovations will help customers reduce operating costs by improving energy efficiency.
HP DSC precise cooling realizes green data center
Traditional data center computer rooms adopt an average cooling design model. However, with the emergence and popularity of rack servers and blade servers, A hybrid model of high-density servers and low-density servers has emerged in data centers. Due to the uneven density of servers, the heat generated is also uneven. The average cooling method of traditional data centers has been unable to meet demand. This has resulted in two current status quos in data centers: First, more than 85% of computer rooms currently have excessive cooling problems; second, only 1/3 of the data center’s power supply is used on IT equipment, and cooling costs account for 2/3 of the total power supply. 3. Therefore, reducing cooling energy consumption is the key to energy saving in data centers.
To address the shortcomings of average cooling in traditional data center computer rooms, HP has launched a new solution based on dynamic smart cooling technology - "HP Dynamic Smart Cooling System" (DSC, Dynamic Smart Cooling). The goal of dynamic intelligent cooling technology is to improve refrigeration efficiency through precise refrigeration. DSC can dynamically adjust the cooling system to reduce energy consumption according to the server operating load. Depending on the size of the data center, energy savings can reach 20 to 45%.
DSC combines HP’s existing innovative technologies in power and cooling, such as HP Thermal Logic, an important component of the HP Blade Server System c-Class architecture, by installing many and Thermal energy detectors connected to the data center can transmit temperature change information of the servers to the central monitoring system at any time. When the detector transmits information that the temperature of a server has increased, the central monitoring system will issue instructions to the nearest cooling equipment to increase the power of cooling to reduce the temperature of that server. When the temperature of the server drops, the central monitoring system will issue instructions to nearby cooling equipment to reduce power based on the new information transmitted by the detector. HP's experimental data shows that the same data center in the HP laboratory without DSC technology requires 117 kilowatts for cooling, while only 72 kilowatts are needed for the DSC system.
HP Blade System: The key production line of the green data center
If the data center is regarded as an "IT factory", then the energy saving and consumption reduction of the "IT factory" must not only be achieved through DSC, etc. Technology realizes energy saving in a "factory-level" environment. The most important thing is the energy saving and consumption reduction of each "production line", and the production line of the data center is IT equipment such as servers and storage. At present, blade systems meet the new requirements for servers in new generation data centers by saving space, facilitating centralized management, easy expansion and providing uninterrupted services, and are becoming an important "production line" of future data centers. Therefore, the energy-saving and environmentally friendly technology of the blade system itself is the key to saving energy and reducing consumption in future data centers.
HP BladeSystem c-Class, HP's new generation of green blade system, is based on an industry-standard modular design. It not only integrates blade servers and blade storage, but also integrates many elements of the data center such as network and power supply. / cooling and management, etc., that is, integrating computing, storage, network, power / cooling and management. At the same time, the innovative BladeSystem c-Class blade system also fully considers the needs of modern data center infrastructure for power, cooling, connectivity, redundancy, security, computing and storage.
Based on the standardized hardware platform, the three key technologies of HP Blade System are beyond the reach of competitors. The first is HP Insight Management Technology - it realizes unified and automated management of physical and virtual servers, storage, network, power and cooling systems through a single console, improving management efficiency by 10 times, and the administrator equipment ratio has reached 1:200. The second is energy intelligent control technology - reducing energy consumption by effectively regulating power and cooling. Compared with traditional fans, super cooling fans reduce server air flow by 40% and energy consumption by 50%. Finally, there is the virtual connection architecture - which greatly reduces the number of cables and eliminates the need for additional switching interface management. Allows servers to be added, replaced, and moved without administrator involvement in SAN and LAN changes.
Currently, HP has a complete blade server strategy and product line, including ProLiant blade servers that support 2-way or 4-way, and Integrity blade systems using Itanium chips, as well as storage blades and backup servers. Blades etc. At the same time, HP BladeSystem c-Class blade server system has been widely recognized by customers. According to the fourth quarter report of 2006 released by IDC, HP ranks first in the world in terms of factory turnover and shipments of blade servers. In the second quarter of 2007, HP's blade market share was 47.2, leading its competitors by 15%, and the gap will continue to expand. As the leader in the blade market, HP BladeSystem c-Class blade system will become the critical infrastructure of the data center.
PARSEC architecture and energy intelligent control: two core strategies for green production lines
As the key infrastructure of the data center, green is one of the important development trends of blade systems and also the data The key to energy saving in the center. In the innovative design of HP BladeSystem c-Class blade system, green is one of its key innovative technologies. Its unique PARSEC architecture and energy intelligent control technology are the two key technologies of this green production line.
HP PARSEC architecture is another innovation of HP blade system for green strategy. Currently, rack servers use several small local fan layouts inside, which results in higher cost, higher power, poor heat dissipation, and consumption of power and space. HP PARSEC (Parallel Redundant Scalable Enterprise Cooling) architecture is a hybrid model that combines local and central cooling features. The chassis is divided into four zones, each equipped with fans that provide direct cooling to the blade servers in that zone and provide cooling to all other components. Because server blades and storage blades have different cooling standards, and the cooling standards are adapted to the basic components inside the chassis, there are even sometimes different types of blades in multiple cooling zones. With HP's innovative Active Cool fans, users can easily achieve different cooling configurations. HP fans are designed to be hot-swappable and can be added or removed to adjust airflow to move it efficiently through the entire system, making cooling more efficient.
HP's energy intelligent control technology (Thermal Logic) is a system-level energy-saving method that combines HP's innovative technologies in power supply, cooling and other aspects. This technology provides embedded temperature measurement and control capabilities. Through real-time thermal monitoring, the heat dissipation, internal and external temperatures of the chassis in each rack, and server power consumption can be tracked, allowing users to understand and match system operating requirements in a timely manner, while setting temperature thresholds manually or automatically . Or automatically turn on cooling or adjust cooling levels to cope with and resolve the heat generated, thereby achieving the most precise power and cooling control capabilities. Through intelligent energy management, customers can dynamically apply thermal control to optimize performance, power consumption and thermal performance to fully utilize the power budget and ensure flexibility.
Using intelligent energy control technology, the number of servers that can be supplied with the same power is doubled. Compared with traditional rack-stacked equipment, the efficiency is improved by 30%. As more servers are plugged into each rack, the amount of power and cooling consumed remains the same or decreases, and the overall design requires fewer components.
Active Cool fan, DPS, power conditioner: every component of the production line must be energy-saving
As a "green production line", HP BladeSystem c-Class blade system uses intelligent energy control Technology and PARSEC system architecture have achieved "production line" level energy saving and consumption reduction, and the technological innovation of each component of this production line is the key technical guarantee for the green production line. For example, the innovative Active Cool fan, the ProLiant power conditioner that implements intelligent power management, and dynamic power adjustment technologies.
The fan is a key component for heat dissipation. Is bigger fan design better? The answer is no. Some blade server products on the market use larger centralized cooling fans, which not only take up a lot of space, are noisy, have poor redundancy, and have air leakage channels, but also have excessive supply and require a high power supply load.
Innovative Active Cool (active cooling) fans are used in HP blade servers. The design concept of the Active Cool fan is derived from aircraft technology. It is compact in size and has a fan blade speed of 136 mph. It generates strong airflow while consuming less power than traditional fan designs. At the same time, it has the characteristics of high air volume (CFM), high air pressure, optimal noise effect, and optimal power consumption. It can cool 16 blade servers using only 100 watts of power. This revolutionary fan is currently applying for 20 patents. Active Cool fans work with PARSEC cooling technology, which can automatically adjust the working status of the fan according to the load of the server, and allow the most energy-saving airflow and the most effective heat dissipation channel to cool the required components, effectively reducing cooling energy consumption compared with traditional cooling fans. Compared to the previous model, power consumption was reduced by 66% and data center energy consumption was reduced by 50%.
In terms of power supply, compared with the independent power supply of traditional rack servers, HP's blade system uses centralized power supply and realizes intelligent power management through innovative ProLiant power regulator and dynamic power adjustment technologies. , adopting targeted strategies based on power supply conditions, greatly saving power consumption.
ProLiant Power Regulator enables server-grade, policy-based power management. The power adjustment protocol can provide power to the CPU according to its application. When necessary, full power is provided for the CPU application, and the CPU can be placed in power-saving mode when not needed. This allows the server to implement policy-based power management. In fact, the power status of the CPU can be controlled in two ways: dynamic and static. That is, the power adjustment protocol can be set to a static working mode with continuous low power consumption, or it can be set to a dynamic mode that automatically adjusts the power supply according to the CPU usage. Currently, the power adjustment protocol can be applied to AMD or Intel chips. For convenience, HP can display the processor usage data through the iLO advanced interface and perform configuration operations through this window. Power scaling allows servers to save power and cooling costs without sacrificing performance.
HP's innovative Dynamic Power Saver technology (DPS, Dynamic Power Saver) can monitor the power consumption in the chassis in real time and automatically adjust the power supply according to demand. Because power supplies are most effective when operating under high load, DPS further improves power consumption by providing power distribution that matches the user's overall infrastructure requirements. For example, when the server has less demand for power, you can start only one pair of power supply modules and leave the other power supply modules in stand by state, instead of turning on all power supply units, but each power supply unit runs at a lower efficiency. . When the demand for power increases, the power supply module of STAND BY can be started in time to meet the power supply demand.
This ensures that the power supply system always maintains the most efficient working condition, while ensuring sufficient power supply, but achieving power savings through lower power supply loads. Through dynamic power adjustment technology, 20 chassis with a power of 0.075/kWh save approximately US$5545 per year.
The increasing energy expenditure of traditional data centers has attracted much attention. While server power supply costs have doubled in the past decade, cooling systems have also brought unprecedented pressure to the infrastructure construction of data centers. In order to solve the problem of rising heat and energy consumption, HP innovatively launched a new generation of green blade system BladeSystem c-Class and a green data center solution based on dynamic intelligent cooling technology DSC. Through HP's innovative PARSEC architecture , energy intelligent control technology (Thermal Logic) and Active Cool fans and other innovative technologies in power supply and cooling components to reduce energy consumption. Depending on the size of the data center, these technologies can save the data center energy by 20 to 45%.
