If your business operates computing infrastructure of any kind – whether a data center or simply a small server farm – one of your largest expenditures is going to be on power. That’s a given. And the more you can do to reduce your power costs, the better.
Once you’ve calculated how much power each of your servers uses, there are two metrics you’ll want to focus on – Power Usage Effectiveness (PUE), and Data Center Infrastructure Efficiency (DCIE). Each is essential to energy efficiency, and each can help you paint a more complete picture of your infrastructure. They’re calculated as follows:
Total Facility Power/IT Equipment Power (PUE)
Let’s say, for example, your facility has a PUE of 1.4. That means over 70% of the power delivered to your data center is used by IT equipment. Basically, the idea is that you want to get your PUE as close to 1 as possible.
Make sense? Good. Let’s talk about some of the tools that can help in your calculations.
American Power Corporation provides one of the most comprehensive energy efficiency calculators on the market. It accounts for everything from power and cooling configuration to total IT load, and includes parameters for determining sizing and loss for an array of different power equipment. It also allows you to immediately generate printouts of your power outlook.
One of the easier tools on the list to use, 42U’s online energy efficiency calculator automatically determines your total electricity used per year, annual power cost, and annual carbon footprint, alongside PUE and DCIE. It also accounts for data on where your facility is located (country and province or state), and lists the optimum levels of PUE and DCIE within that region. Lastly, it provides a detailed explanation of all the facts and figures.
3. The Green Grid
The Green Grid is unique in that it separates your data center components into Modules and Core. Core components are part of your facility’s central infrastructure, while Modules are IT elements such as servers, switches, and routers. Each component can also have several ‘types’ assigned to it, including HVAC, Building Management Systems, Power, and Physical Security.
4. Galileo Connect
Targeted mostly at UK users, Galileo Connect tends to be a bit limited at times. All calculations are done in Pence and Pounds, and the data center/room is locked at 2000 meters square with 1500 watts per meter of square load density. At the same time, it also gives users a huge range of environmental options like solar panels and water cooled chillers.
Dimension85’s tool is far more minimalist than the other entries on this list. While some users may find that minimalism and simplicity attractive, others may find the fact that it does not offer advice on energy savings or energy efficiency a bit off-putting. At the same time, it’s useful as a quick reference tool
6. Cisco UCS
Cisco’s UCS power calculator is another of the more full-featured options on the list. Equipped with an intuitive user interface and the ability to create multiple templates and projects to store and calculate configuration data. Not only does it allow you to calculate both DCIE and PUE, its RESTful API allows your development team to easily connect it with a range of third-party applications, generating calculations based on raw data, rather than what you input into the app.
7. Dell Energy Smart
Dell’s Energy Smart Solution Advisor is actually one of a pair of tools, alongside its Data Center Capacity Planner. Together, they allow your administrators to tune their servers and other IT equipment to maximize efficiency. Both tools support a wide array of products and configurations.
8. HPE Online Power Calculator
Provided by Hewlett-Packard, The HP Enterprise Power Calculator is made primarily for HPE ProLiant G5 and earlier server models. It allows you to easily estimate power consumption and component selection at a system, rack, and multi-rack level. HP also offers the HPE Power Advisor, which is designed for HP’s newer servers.
9. Schneider Electric’s Data Center Capital Cost Calculator
The Data Center Capital Cost Calculator is designed to be used early in the planning stages of an infrastructure deployment. It allows you to determine expectations for what a project might cost, and to determine that your system’s power demands remain within your budget. More importantly, it will also help you understand the different choices available to you, and their impact.
10. Tripp Lite Power Load Calculator
Last but certainly not least, Tripp Lite’s UPS Power Load Calculator allows you to make intelligent purchasing decisions regarding your UPS system. It determines the total load of the equipment you want to use, ensuring you won’t select one that’s unable to handle your power demands. According to Tripp Lite, it’s recommended that you use a UPS with an output capacity at least 20-25% higher than the total load to allow for spikes in power consumption.
Know Your Power
Power efficiency is critical to effective infrastructure management. Whether you’re running a data center or simply a server farm, knowing how much energy your systems require – and knowing how to most effectively use that energy – is at the heart of your success. By using the tools on this list alongside effective power monitoring, you’ll ensure that you can.
