  2. 2. ABOUT THE HCL INFOSYSTEMS LTD. HCL Infosystems Ltd.,a subsidiary of HCL, is an India-based hardware and systems integrator with a focus on emerging markets. It has a presence in 170 cities and 505 points of presence reaching 4000 towns throughout India and operations in emerging markets including South Asia, Middle East & Africa. It has a strong distribution network of 93,000 outlets in over 9,000 towns in India. Its manufacturing facilities are based in Chennai, Pondicherry and Uttarakhand. It is headquartered at Noida. The company operates under three primary segments: Computer Systems and related products and services Telecommunication & Office Automation Internet and related services.
  3. 3. INTRODUCTION TO DATA CENTER A data center or computer centre (also datacenter) is a facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and security devices. Large data centers are industrial scale operations using as much electricity as a small town. It is also known as server rooms in general language
  4. 4. History • Data centers have their roots in the huge computer rooms of the early ages of the computing industry. • The boom of data centers came during the dot-com bubble. Companies needed fast Internet connectivity and nonstop operation to deploy systems and establish a presence on the Internet. • . Many companies started building very large facilities, called Internet data centers (IDCs), which provide businesses with a range of solutions for systems deployment and operation. • There is still a lot of development being done in operation practice, and also in environmentally friendly data center design. • Data centers are typically very expensive to build and maintain.

  6. 6. REQUIREMENTS FOR MODERN DATA CENTERS Various aspects of the data centers include: • Facilities: layout, power/cooling, physical security; • System infrastructure: servers, networking, storage, and security; • Applications, infrastructure mapping & dependencies; • Service management and operations considerations
  7. 7. DATA CENTER PHYSICAL INFRASTRUCTURE • A data center can occupy one room of a building or more floors or entire building. • Most of the equipment is often in the form of servers mounted in 19 inch rack cabinets. • Three elements of the building of data center are facility topology design (space planning), engineering infrastructure design (mechanical systems such as cooling and electrical systems including power) and technology infrastructure design (cable plant). • The aim is to create a master plan with parameters such as number, size, location, topology, IT floor system layouts, and power and cooling technology and configurations.
  8. 8. MECHANICAL ENGG. INFRASTRUCTURE DESIGN • It is involved the interior environment of a data center, such as heating, ventilation and air conditioning (HVAC); humidification and dehumidification equipment; pressurization etc. • Ventilation 1. Methods for ventilating a building may be divided into mechanical/forced and natural types. 2. Mechanical" or "forced" ventilation is used to control indoor air quality.

  10. 10. Heating • Central heating differs from local heating in that the heat generation occurs in one place, such as a furnace room in a house or a mechanical room in a large building (though not necessarily at the "central" geometric point). • The heat is generally produced by the combustion of the fossil fuel , and the produced is steam is circulated by the air ducts. • Increasingly, buildings utilize solar-powered heat sources, in which case the distribution system normally uses water circulation.

  12. 12. ELECTRICAL ENGG. INFRASTRUCTURE DESIGN • The main aspects of the electrical engineering infrastructure are utility service planning; distribution, switching and bypass from power sources; uninterruptable power source (UPS) systems; and more. • These design are of international energy standards and meet the business objectives. • Electrical configurations should be optimized and operationally compatible with the data center user’s capabilities. • Modern electrical design is modular and scalable, and is available for low and medium voltage requirements as well as DC (direct current).

  15. 15. MODULAR DATA CENTER • A Modular data center is a alternative to traditional data centers. • A Modular data center can be placed anywhere data capacity is needed. • Modular data center systems consist of purpose-engineered modules . • It offer scalable data center capacity with multiple power and cooling options. • This can be shipped anywhere in the world, and can be added or integrated in any other module. • Modular data centers typically consist of standardized components, making them easier and cheaper to build.
  16. 16. Containerized data centers In a portable data center the entire data center equipments are fitted into a Standard shipping container which can be moved by a truck onto a ship.
  17. 17. Flexible data center Flexible Data Center is constructed of sheet metal components that are formed into four data center halls linked by a central operating building.
