  2. ERS DATACE CENT NTERS • What is a Dataceneter? • What makes up a Datacenter (Processing, storage, networking, infrastructure)? • What is searched in a Datacenter (High availability, efficiency, security)?

  3. R? WH WHAT IS A T IS A D DATA CE A CENTE TER? • Data centers are facilities with optimal conditions for the operation of processing equipment, storage, communications or other IT device. • The Datacenter houses devices that support an activity that needs to be in continuous operation (Ej: Banks). • The malfunction of a datacenter can cause large losses.

  4. Wh What' at's in in a a Dat atacen acenter er? • Computer equipment, storage and communications (High density equipment) • Physical infrastructure • Essential applications and services (Services that can not stop working) • Critical information (Accounting, suppliers, customers, etc.)

  5. Wh What at are y e you ou lo look okin ing g for or in in a da datacen acenter er? • High availability of IT equipment (Banks, stock exchange) • Redundancy • Reliability • Flexibility • Scalability • Modularity • Efficiency • Security

  6. Cl Classifi assification cation ac accor cording ding to to "Ti Tier er" • Express the availability of the datacenter. • The datacenters are classified into 4 levels, with Tier 4 being the most robust: • Tier 1: Basic elements UPS, air, safety without redundancy. Cold maintenance (You must de-energize). It does not tolerate failures. Availability 99.671% • Tier 2: Complies with Tier 1. Some critical redundant elements (UPS, air). The only way of electricity supply and cooling. Something tolerant to failures. Availability 99.741% • Tier 3: Complies with Tier 2. All critical redundant equipment. All servers have two sources. Several power lines. Great fault tolerance Hot maintenance. Availability 99.982% • Tier 4: Complies with Tier 3. Several power lines for air conditioning equipment. Availability 99.995%

  15. Power er: : PD PDU • Power distribution unit (Power Distribution Unit) • Adequate power delivery for datacenter equipment • Types of PDUs: • Basic • Monitored ("Metered") • Switched ("Switched") • Intelligent • Administration of the energy consumed by the datacenter • Understand how energy is consumed in a datacenter • Monitoring and remote on / off • Increase Efficiency • Decrease operating cost • Some PDUs include ATS (Automatic Transfer Switch)

  18. Environm Environment ental con al control: trol: Hea eat, t, en ener ergy an gy and po d power er • Heat is a form of energy, such as electrical energy or mechanical energy. • Temperature is a measure of the movement of molecules. • The heat can be expressed as movement of the molecules, that is to say, it is related to the temperature. • The power represents the amount of energy that is spent for a certain time

  19. Environm Environment ental Con al Control trol: : La Laten ent t he heat an at and se d sens nsib ible le he heat at • Sensitive heat: Heat that is reflected in a change in temperature • Latent heat: Heat that is reflected in a change of state (water evaporation). There is no change in temperature.

  20. En Envi viron ronment mental al Con ontrol trol: : Hu Humi midity dity • Humidity is the amount of water present in the air. • It is expressed as relative humidity and absolute humidity: • Absolute humidity: Amount of water (Usually in grams) per unit volume of air (Usually cubic meters) • Relative Humidity: Represents the portion of water in the environment with respect to the amount needed for condensation. It is expressed in percentage. • In datacenters it is important to keep the relative humidity in an adequate range.
