2 Agenda Agenda and Intro About Vakıfbank DC Energy Consumption breakdown DC Cooling Efficiency in DC Project phases Strategy and Site selection Design and Specifications Implementation and Tests Management and Operation Vakıfbank Datacenter Project Vakıfbank DC Project Views 2

3 Vakıfbank Intro Purpose of Establishment Established on Jan Best utilizing the foundations monies. Contributing to the savings of the country Use modern banking practices An initial capital of 50 million TL Reaching Corporate and individual customers in a most efficient manner through its internet and telephone banking services. Size 7th Largest Bank in Turkey 900+ Branches 3400 ATMs units of POS International Branches ; New York, Bahrain and Arbil VakıfBank operates in Austria with a subsidiary, VakıfBank International AG, which has branches in Vienna, Cologne and Frankfurt

5 DC Cooling efficiency and Project Phases DC Roadmap Site Selection Datacenter Design and Specifications Datacenter implementation Test and Commissioning Datacenter Management & Operations 5

6 DC Roadmap / Strategy and Site Selection IT Growth and Business of the organization Right sizing DC to meet IT growth Invest on Energy efficiency or not? Site selection by considering Energy Efficiency metrics Location, Climate, Availability of water, wind and other natural resources Water storage Shape and size of the site/building Permits Green field vs Brown field? 6

7 DC Design and Specifications DC Sizing ; Space, Power, Cooling Technologies to be used for max efficiency Datacenter layout Air and water quality, filtering needs and costs Water availability, storage and cost Free cooling + Mechanical cooling needs (Direct/İndirect air, adiabatic, DX, chilled water cooling? Available free cooling / Energy efficient solutions in the market Products Standard/Custom Air duct / Pipes Risks Capacity, Purchase, Service Maintenance and Operations 7

8 Implementation, Test and Commisioning Implementation should be done according to design to meet energy efficiency targets. Installation quality and easşness of operation should be considered. T&C Should be done to check system performance and compliance to design targets Systems should be tuned to perform targeted efficeinecy metrics 8

9 Datacenter Management and Operations DC Cooling set points (ASHRAE-Guidelines and more ) Operate DC close to the upper limit of the recommended range (27 C). Every degree can save or waste energy Observe and evaluate outdoor temperature to maximize free cooling Maintenance of Free cooling equipment and filter cleaning/replacement. Consider IT Equipment and IT Load while deciding on set temperatures. Automation Deciding on cooling scenarios for max. efficiency Operating at high outdoor temperature Operating at transition times (Spring, Fall seasons) Operating at Winter/Cold seasons 9

10 Vakifbank Project development DC should meet Bank s 10+ years needs Vakıfbank VIT Project requirement analysis; Network Server Storage Defining infrastructure components to meet IT needs MV Transformers Generators UPSs Cooling systems Structured data cabling White space Others VM Tier level, Availability, Reliability UI, TIA, Ashrae, Cobit DS12 like standards and Industrial best practices. Certifications DC Maturity Model and Operations

11 DC Design criterias in brief Datacenter should meet Vakıfbank 10+ years needs Energy efficiency metrics Energy efficient Infrastructure components. (Cooling Chiller/CRAH/CRAC/Pumps, UPS, TR, etc ) High set points (>24 C) Cold aisle containment Electrical cable sizing, Data cabling on the ceiling. EC Fans and VSD Pumps /Motors <1,5 PUE target Compliance to standards Min UI Tier III Design, Construction and Operations Upgradable to Tier IV. Running DC operations on a level equivalent to UI Operational Sustainability Gold level Comply to TIA 942 specs except site limitations TIA942 compliant data cabling and labelling (Tier IV) Comply to COBIT DS12, ISO 27001, PCI like physical security needs.
