This is the full cost per kWh (kilowatt hour) that your utility or data centre provider charge you for the power consumed by your IT equipment (VAT is not included). One of the largest cost drivers for data centers and customers is power. We examine techniques for calculating power consumption of servers, racks, and cabinets. Their contribution is to reduce the total data centre power requirement relative to server consumption. We look at the differences between metered and unmetered power and how geography plays into the cost of electricity in kilowatt hours. Dedicated Servers: What Are The Different Types of Dedicated Servers? We’ve defaulted to the UK average if you are unsure. The first term is watt (W). However, certain data centers may require a monthly minimum of 40-50% of the breakered power total. Designing a data center that features row-based cooling and a scalable UPS? ... possible through efficiency improvements. Figuring out the difference between them can be a challenge if you're not an electrician or into DIY home repair, but it's really quite easy. 1. A kilowatt is equal to 1,000 watts. A typical PUE is 2 to 2.5, which means that 2.25 times more power is required to run the data centre than powers the servers. Yet the average coal-fired power plant, the most carbon-intensive option available, has an emissions intensity that is less than one-fourth of this value—around one kilogram CO 2 /kWh (U.S. EIA 2020). Ark Data Centres Limited registered in England and Wales number 5656968. It is no secret that power is one of the most important considerations in data center site selection. Next, you will want to solve for kilowatts. You can determine power requirements by researching your server manufacture specifications online. The Real Cost of a Data Center Build. Savings are for illustrative purposes only.The UK average power cost figure is based on the latest BEIS survey of energy suppliers, and includes all applicable costs except VAT. Based on the figures you've supplied, it looks like our standard rates might not save you money - but why not get in touch and challenge us to beat your current deal? This website uses cookies to improve your experience. If your utility costs are $.139 per kWh, your daily costs to run your server are $1.248 per day or $37.44 per month. In fact, IDC reports that energy consumption per server is growing by 9% per year globally as growth in performance pushes demand for energy. This is for illustration purpose only and we use the base rent, utility power cost and terms to calculate the savings. Use 3,680W instead of the maximum 4,600W in figuring your costs. There is rarely a markup on electrical prices from a data center. In a data center, typically 20-40 % of the operating cost is related to data center power costs. In a perfect world PUE would be 1.0 but typical figures are around 2.0 (source). See also: How Server Power Supplies are Wasting Your Money It is also important to understand how volts (V) and amps (A) factor into the equation. Companies can outsource power and bandwidth costs by leasing space in a data center while keeping full control over hardware and data. The 2,649.60 kWh is the amount of power your servers and related hardware use in a month. It takes an unbelievable amount of electricity to power and cool an entire data center. The average cost of a kWh in the United States is $.139 cents per kWh. To get kilowatts per hour, simply take kilowatts and multiply by hours during a time period. This is related to the number of Central Processing Unit (CPU) sockets and has remained static since 2007: 118W for single socket servers and 365W for two socket servers (Shehabi et al, 2… The table below provides the average annual cost to power a single rack in a data center in the US for a variety of rack PDU capacity and rack input options. For example, 230V multiplied by 20A equals 4,600W. © 2020 Datacenters.com. It takes an unbelievable amount of electricity to power and cool an entire data center. Nevertheless, the largest hubs for data centers in Europe are found in the abbreviation FLAP-D (Frankfurt, London, Amsterdam, Paris and Dublin). Globally, data center power consumption has been growing. All rights reserved. Now that you have an understanding of terminology and equations, how do you calculate server power usage? Watts (W) = Volts (V) x Amps (A)1 Kilowatt (kW) = 1,000 Watts (W)1 Kilowatt Hour (kWh) = 1,000 Watt Hours. For more accurate results, test the watt utilization off one server with all of the cores fully loaded with a watt meter or amp clamp volt meter. Compared to traditional rack servers, blade servers can perform the same work for 20- to 40-percent less power. Getting to Know: Pegasus Data Center Cleaning, Data Center Power Optimization: Increase Efficiency with a Data Center Audit, Data Center Cooling: Future of Cooling Systems, Methods and Technologies, 10333 E Dry Creek Rd, Suite 430, Englewood, CO 80112. The average annual data center cost per kW ranges from $5,467 for data centers larger than 50,000 square feet to $26,495 for facilities that are between 500 and 5,000 square feet in size. We'll assume you're ok with this, but you can opt out if you wish Accept   or   Read More. This is the total amount of power in kW (kilowatts) that your IT racks consume. We’ve defaulted to the UK average if you are unsure. As another example, a base rate for 1 kWh might be 12¢/kWh but 20¢/kWh for usage over 1,000 kWh per month. This is the full cost per kWh (kilowatt hour) that your utility or data centre provider charge you for the power consumed by your IT equipment (VAT is not included). At 10 cents per kilowatt-hour for utility power, a data center with 1,000 servers could save up to $175,000 per year simply by using more blade servers. The cost per kWh shown for each state are the official 2010 Average Retail Price of Electricity published by the Department of Energy (DOE) / Energy Information Administration (EIA). Industry average is currently around 4kW per rack, around 20kW per rack for HPC environments. Power drawn is partially related to usage, expressed as a percentage of maximum power. The answer is 720 hours in a month. You have done all of the heavy lifting in determining server power requirements. The most common pricing model is referred to as metered power. Having grown from around 11 million in 2006, as of 2020 there are an estimated 18 million servers deployed in data centers globally (Shehabi et al, 2016). For example, you have a server that requires 400W and it runs 24 hours. Make sure to comment at the end of this article with any tips or tricks that you use to calculate power usage and costs for data center colocation. If you are unsure of your specifications or do not want to test your servers using a watt meter, you can use watts (W) equals volts (V) multiplied by amps (A) equation from above (W = V x A). Very (!) In fact, Gartner estimates that ongoing power costs are increasing at least 10% per year due to cost per kilowatt-hour (kwh) increases and underlying demand, especially for high power density servers. All that is left is pricing per kilowatt hour and calculating total power costs. One of the largest cost drivers for data centers and customers is power. Benchmarking your data center’s energy efficiency is a key first step towards reducing power consumption and related energy costs. Server colocation is an excellent option for businesses that want to streamline server operations. It is important to know watts (W), kilowatts (kW), and kilowatt hours (kWh). You need to know basic terminology before learning to calculate power usage and costs. Considering that global data centers recently consumed around 205 billion kWh, for this claim to be true, their average electricity emissions intensity would have to be around 4.4 kg CO 2 /kWh. A kilowatt hour is equal to 1,000 watt hours. Watts (W) equal volts (V) multiplied by amps (A). Based on your power requirements, you could save: Get in touch with us today to start saving. Most data centers do not markup electricity prices to the customer. For example, an HP ProLiant DL380 G7 Server has several power configurations with maximum rated wattage of 460W, 750W, and 1200W. Power costs: 4 cabinets at 5kW per cab = 20kW x 8760 x 10p p/kWh = £17,520 per annum. The Nordics, and Norway in particular, have considerably lower power prices compared to the rest of Europe. There may also be annual increases charged by the data center to account for the increases they are charged by the utility company.
