Currently, data centres in the country are mainly built by operators, internet companies, large enterprises and state-owned companies, with the following characteristics:
(a) 1 heavy asset: from a range of construction, power supply, back-up power, air conditioning, cabinets, fire protection, renovations, for example, 2,000 cabinets (5 kw/rack), excluding it equipment, the construction investment was approximately $300 million
(b) high technical threshold: from the above construction elements, many professions are involved, and the content of the idc is also involved, with a very significant impact on subsequent operations if technical choices are wrong
It is difficult to operate: building a data centre is easy, it is difficult to maintain stable operations over the long term, and it is difficult to do so in terms of the fixed costs of transporting the data as a whole。
The data centre is profitable in two main ways: in the room rental and cloud operations. The cloud business involves the development of internet products in a variety of models that make it difficult to analyse for profit; today we are analysing the rental of cabinets。
As one of the eight central nodes of the east and west count, guizhou analyses 2,000 cabinets (5kw/rack):
Construction cost: the amortization cost per container is approximately $12,000 per year and the cost of electricity is $3. 31 million (0. 5417/kwh) for a total of $451,000/year, if calculated at the depreciated value of 10 years
2 rental: based on the multiple evaluation projects in which the author participated, the rent for the 5kw single cabinet was approximately $4,500 per month, or 54,000 yuan/year。
From a simple calculation, each cabinet is approximately $0. 90 million per year, which is already very attractive for 0. 72m2. This is not the case, however, because the above construction costs do not include such costs as taxes, transportation fees and bank interest, and profits can slip away at any time in the hands. In order to make a real profit, three points must be taken: electricity, net charges and large customers。
One electricity fee: the theoretical value of the electricity bill per 5kw cabinet was calculated to be $3. 31 million per year. In fact, the 1kw is a design value and cannot really be filled with equipment that can consume 5kw. According to statistical data (confidential), the average energy consumption of 5kw single cabinets is between 3. 5 and 4 kw, which, at 3. 8 kw, saves 0. 8 million dollars per year
2 net fees: because of differences in the number of cabinets and the type of business performed by clients, network rental fees are generally not included in the rental of cabinets, for 2,000 cabinet-sized data centres, the cost of the network is 12 million less per year, or possibly hundreds of millions more, and for operators, the money lost on the cabinet is recovered from the network fees
3 clients: for customers who lease cabinets, the equipment, once installed, will not be easily relocated, so it is usually long-term clients (5-10 years)。
