One of the fundamental decisions in the design of data centers, server rooms and network closets is which uninterruptible power supply (UPS) systems to use. You cannot be certain that the power you receive from your local utility will be suitable for your equipment, or that it will always be available. And even when you are receiving good-quality power from the utility, equipment inside your facility (such as electric motors) can introduce power problems.
A network/server UPS system conditions input power 24x7 to ensure that your equipment always receives reliable power and protection from damaging and disruptive power problems. A network/server UPS system also supports your equipment during power failures, providing enough battery backup runtime to outlast shorter outages. During longer outages, the UPS system will provide enough runtime to save files and gracefully shut down systems or to ensure that equipment is powered until standby generators are ready to support the load.
Data centers are large, important investments that, when properly designed, built, and operated, are an integral part of the business strategy driving the success of any enterprise. Yet the central focus of organizations is often the acquisition and deployment of the IT architecture equipment and systems with little thought given to the structure and space in which it is to be housed, serviced, and maintained. This invariably leads to facility infrastructure problems such as thermal “hot spots”, lack of UPS (uninterruptible power supply) rack power, lack of redundancy, system overloading and other issues that threaten or prevent the realization of the return on the investment in the IT systems.
When working with data center and commercial facility electrical systems, shocks of 100mA to more than 2,000mA are possible—definitely in the realm of serious harm to humans and property. Energized electrical equipment also presents the risk of arc flash caused by electrical faults that produce powerful explosions. When dealing with commercial and industrial electrical systems, such as uninterruptible power systems (UPSs) and their batteries, data center and facilities managers need to be aware of these risks, especially since some repair and maintenance procedures require working with a unit that is still energized. There are ways to minimize the risks to employees, equipment and the field technician performing the service.
This paper answers some common questions about UPS maintenance, how to reduce the risks associated with servicing UPSs and batteries, and how to qualify a UPS service provider.
Cloud computing vendors and colocation data centers make every effort to maximize the scalability, efficiency and agility of their data centers. As a result, more and more of them are looking into replacing older, transformer-based centralized power protection schemes with distributed architectures in which uninterruptible power systems (UPSs) reside in the white space (or data hall).
This white paper describes the advantages of positioning UPSs in the white space as well as the essential qualities to look for in a white space-ready UPS.
In their search for top-of-the-class uninterruptible power systems (UPSs) for their demanding data center environment, WUSD wanted a system that would keep everything backed up with enough runtime for a graceful shutdown, but was also easily scalable. Equally important, the district wanted seamless integration with their virtual environment.
Find out how the Eaton 9390 UPS and the Eaton Intelligent Power Software (IPS) Suite made the grade.
Though power protection solutions vary in numerous ways, all but the largest data centers use basic approaches when deploying uninterruptible power systems (UPSs): Either they distribute many smaller UPSs among their server racks or they install one or two large UPSs centrally within or near their server room. This white paper outlines each architecure's pros and cons.
Uninterruptible Power Solutions are often solved at the facility level with unnecessarily large, inefficient, expensive and complex AC UPS systems. While this provides an easy demarcation line between the facility and end equipment, with each focusing on a different part of the problem, it also results in overall operating efficiency and total cost of ownership being difficult to ascertain and optimize.
