3 Unique Identification Authority of India (UIDAI) Overview UIDAI is an attached office under Planning Commission of India which develops and implements the necessary institutional, technical and legal infrastructure to issue unique identity numbers to Indian residents. AADHAAR is a 12-digit unique number given by UIDAI to Indian residents as a proof of identity Enrolment is a one time process for the resident to obtain Aadhaar UIDAI s two captive data centres shall host the; Residents basic demographic and biometric 1 information captured by UIDAI while issuing 12-digit AADHAAR number. Support to various applications for welfare 2 schemes of State & Central Governments Authentication services to various authentication User Agencies e.g; Central 3 Government Agencies / bodies / departments, State Governments, PSUs, Banks etc DC Location-A DC Location-B Page 3

4 What is UID (Aadhaar)? Key Features Only Numbers No Smart Cards Random Numbers No Intelligence, No Profiling All Residents Including Children Uniqueness Ensured through biometric attributes No Guarantees to Citizenship, Rights, Entitlements Ubiquitous Authentication From No ID to Online ID Ensuring Security and Privacy of Information Details Captured Demographic Details Name, age/date of birth, gender and address of the resident (compulsory) Biometric Photograph, fingerprint scan, iris Aadhaar is a 12-digit unique number issued after biometric (iris and fingerprint) and demographic de-duplication Enrolment Hierarchy UIDAI Reg. Offices Registrars Enrolment Agencies Enrolment Stations Apex Body Across the country State Govts., NPR, banks etc Empanelled by UIDAI, engaged by registrars Across the country Residents ~40, Bn Page 4

6 The UID Technology Solution It encompass all application software, system software, infrastructure (including IT systems, Private Cloud of Data centres, Network, Servers and Storage, for production, staging and testing) It shall enable to issue UID numbers, update resident information and authenticate the identity of residents as required Page 6

7 Data centre Planning Key decisions (1/2) Key decision points Site selection and land acquisition for two data centres across different geographies Business requirements & IT road map for 1.6 Billion UID enrolments till 2030 Uptime availability? Selecting Tier I/II/III/IV based on business criticality? What cost? High electricity power consumption expenses 5yrs electricity expense ~ CAPEX + 5yrs OPEX* Vertical/horizontal expansion and number of floors in the building * (OPEX- Manpower and equipment maintenance cost) Page 7

8 Data centre Planning Key design considerations (2/2) Guidelines Design Considerations Building Design Data Centre Building to be based on LEED practices for energy efficiency Design based on ASHRAE guidelines Adopting key design guidelines from TIA-942 Tier-III certification from Uptime for data centre LEED certification (Gold) for data centre complex Design based on latest NFPA code and standards Efficient system design at partial load utilization Modular & scalable system design and provision for seamless integration Selected 3 types of rack density (6.5/9.5/13.5 kw) for efficient load utilization & separate room for respective rack density High Avg. rack density (7.8 kw) to optimize space Selecting an highly efficient solution and technology Achieve lowest annual average PUE (< 1.55 /1.6 at Indian environmental condition) conditions) as as per per Green Grid Grid Methodology DC 24*7 24x7 monitoring and measurement DG Fuel bulk storage tank (36hrs) & 2hrs Fire Rating Continuous security and protection from unforeseen or natural calamities Selected tier III DC at each location on the basis of business criticality analysis Building structural floor slab strength 1500kg/ Sq Mtr Clear floor height > 4.7 Mtr Physical Security & perimeter security Seismic zone compliance Page 8

9 Green Data Centre - Selecting efficient solution for better annual average PUE (1/2) Electrical Components 3-phase distribution instead of 1-phase- low power distribution losses Bus Bar Trucking for rack distribution and Main Utility-low power distribution losses PDU transformer with higher efficiency 97.5% IGBT based rectifier transformer less UPS, higher efficiency >95%, low THDi < 3% & higher input PF on partial load Using high efficiency electronic ballasts controlled through occupancy sensors Diversity factor 70% on overall estimated IT load for higher equipment load utilization to have better equipment efficiency Designed for ; Lowest targeted annual average PUE in India 15~20% reduction in PUE vs most of the operational data centres in India ~0.5 MUSD/Year/data centre savings vs most of the operational data centres in India DCIM Components Manage and Measure: Use of data centre infrastructure management software Penalty/Incentive for data centre operation agency on account of exceeding/reducing PUE from the target value Page 9

10 Green Data centre-selecting efficient solution for better annual average PUE (2/2) Air cooled screw chiller selected over water cooled chiller considering Indian environmental conditions : The annual average PUE estimated to be approx 1.6 with air-cooled chiller vs 1.62 with water cooled chiller > 50% IT Load Annual average PUE for Water Cooled chiller marginally better. But there is higher cost of maintenance for water cooled chiller which nullify the effect of marginally better PUE Water availability is a constraint for water cooled chiller as it consumes significant amount of water Mechanical Solutions Higher Chiller efficiency ; Low kw/tr ~.93,COP ~ 3.3 as per ARI design conditions at 100% Load Higher design entering/leaving chiller water temp; 12 / 19 Deg C Use of adiabatic cooling and VFDs for chilled water distribution pumps Separate room for respective very high/high/medium density rack and free cooling used for UPS room & Battery Room Free Cooling/Economizer for server room not used as it requires high CAPEX while energy savings is marginal considering the environmental condition and quality of air in India. Best Practice to be followed BYPASS Air Mgmt - Close floor gaps in unused cabinets & fit cable skirts where cables come up through raised floor Recirculation Air Mgmt- Fit blanking plates in between server cabinets & position high powered servers in the middle (and bottom) of the row Adjust Air Supply Temperatures, raise the air temperature and remain within the ASHRAE recommendations of 64.4F (18 deg C) to 80.6 F (27 deg C). Raising the temperature reduces the overall energy required for cooling Page 10
