Determining the location of a data center is one of the crucial decisions for a company as it is based on strategy and goals of a company. In any discussions related to data center sites, few factors come up frequently like power, telecommunication, data center tiers, clean power, site selection and so on. Management looks for Total Cost of Ownership (TCO) and makes decisions based on their long-term and short-term goals.
Site selection plays an important role for the same as it will have direct impact on cost and TCO. In below sections, we will discuss more about factors affecting site selection and a high level process/methodology for the same.

Few things which needs to be looked are: Natural disasters (Flood, Hurricane, Tornado etc.) – probability and frequency of occurrence at the said location; Environmental hazards – Impact and degree of affect; and Climate – Climates which support free cooling (outside air cooling) will be an added advantage.
Electricity – Electricity or power is important factor as it is one of the chief constituent to operating cost of a facility. we need to understand.

Following list will help in this regard: Fibre backbone route and its proximity – How near a fibre backbone to the selected site. It will help to gauge addition investments required from backbone route to the exact data center location; Type of fibre – Will affect speed and transmission; Carrier type and support – What all carriers are present in the vicinity and their support & service model in place; and Latency – Transaction time/latency will be an important factor
Tax Rates – Another important aspect is tax rates prevalent at a particular location. Following needs to be considered: Property tax; Corporate tax; and Sales tax.
Construction – While building a data center at any particular location, construction cost and options play a major role. Following aspects should be considered for making a decision: Construction industry maturity, experience, process in place and technology availability at the considered site; and Labour - Availability and cost of labour at the considered place.

5. Detailed investigation – Once few sites are shortlisted based on initial investigation, it’s time to do detailed analysis. It will include having detailed discussions with various stakeholders, look for actual data like geo-technical studies etc., discuss about construction options and cost, negotiating on best prices etc.
6. Analysis, recommendation and approval – Post detailed investigation, it’s time to analyze the data, make recommendation and present the options to management for their feedback and approvals.
