According to the region and severity of stormy conditions, these storms may be referred to as typhoons or tropical cyclones. Tornado and Hurricanes can create stress and dramatic issue for data center. For example, what happened in hurricane Katrina 2005 made huge impact on datacenters that are located in New Orleans. Prior to hurricane Katrina, the department of Agriculture moved its data center from New Orleans to Kansa City, Missouri [18]. Tornado do accrue where a thunderstorm is possible, and there is history of places have been struck with tornados and Hurricanes [19]. Still hurricanes and tornedos are rare because they typically get weak at the cost line of weak Africa and travel west of the Atlantic Ocean. C. Earthquake Earthquakes occur every day around the world, but large ones and potential for future large quakes. These large earthquakes need to be taken into data center site location consideration. The west coast of Africa consider to be safer form these quakes comparing to other continents. There are countries in the west coast of Africa got hit by earthquakes, such as, Democratic Republic of the Congo and South Africa. In general, Africa as a continent has lower number of earthquakes comparing to other continents, South Africa is the spotlight of earthquakes in the continent follow by Egypt [19]. The following figure shows the major earthquakes in the world and clearly showing that Africa is totally out of the spot. Figure 7 shows the major earthquakes in the world since 1900. [20] D. Tsunami
In our example to estimate the total coast, we will assume that the facility is 30000 sq ft and occupied with 50% 3.3.2 Cost of The value of real estate is estimated as the ration of Net Operating Income (Excess of Gross Operating Income over Operating Expenses) and the Capitalization rate (Like P/E rate). The capitalization rate is a representation of the ratio of current valuation to expected return. The real estate value of commercial property is given by:- Realestate = NOI / Cap rate For a data center, however, a distinction is made between the total space, active space, and leased space However with the rate of occupancy of data centre space, the formula becomes: Cost = (NOI / sq ft) (A data centre) (% Occupancy) (Cap rate) The average rate renting space are shown the table blew Country Average rent (per sq ft) Lagos, Nigeria $6.48 – 8.00 Accra, Ghana $3.7-5.1 Dakar, Senegal $ 5.5 – 7.8 Cape Town, Africa $ 10 - 14 Average rent is Cost Space = (NOI / sq ft) (A data centre) (% Occupancy) (Cap rate) Assuming Cap rate as 10% and Operating Income as NIL, Average Rent = NOI
Lagos, Nigeria $0.18 ($0.18 x 24 hr x 30 days x 0.5) / 106 = 65 / watt / month Accra, Ghana $0.8 ($0. 8 x 24 hr x 30 days x 0.5) / 106 = 288 / watt / month Dakar, Senegal $0.42 ($0.42 x 24 hr x 30 days x 0.5) / 106 = 151 / watt / month Cape Town, SA $0.17 ($0.17 x 24 hr x 30 days x 0.5) / 106 = 61 / watt / month J1 = P rated / P Consumed hardware P Consumed hardware = (Given) 50% ie 5 kwh J1 = 10 / 5 = 2 K2 = J1 U$,A&M colling / U$,grid = 2 x 0.5 / 1 = 1 Further, typical state-of-the art data center has a cooling load factor of 0.8, i.e. 0.8 W of power is consumed by the cooling equipment for 1 W of heat dissipation in the data center. Cost Cooling = (1 + K2) L1 U$,grid P consumed hardware -( As (1) above) TABLE - C Country U$,A&M, cooling Cost Cooling - (A) Rate /sqft Lagos, Nigeria 65 / watt / month (1 + 1) (0.8 x 65 x 5) / 106 = $ 520,000 (A)/30000= $17.33/ft Accra, Ghana 288 / watt / month (1 + 1) (0.8 x 288 x 5) / 106 = $ 2,304,000 (A)/30000= $76.80/ft Dakar, Senegal 151 / watt / month (1 + 1) (0.8 x 151 x 5) / 106 = $ 1,208,000 (A)/30000= $40.27/ft Cape Town, SA 61 / watt / month (1 + 1) (0.8 x 61 x 5) / 106 = $ 488,000 (A)/30000= $16.27/ft
