Why rightsizing your UPS should be part of your data centre modernisation plan
Wendy Torell, senior research analyst at Schneider Electric’s Data Center Science Center, says companies that overlook fundamental data centre modernisation practices of their physical IT infrastructure systems run the risk of unplanned downtime that can cause serious disruption to critical business processes
U
ptime Institute found that almost one third (31%) of enterprises experienced an IT downtime incident or severe degradation
of service in the past year. Unplanned downtime is also expensive. Uptime Institute highlighted that around 33% of outages reported costs over $250,000.
Neglecting to modernise the data centre also means that organisations are failing to take advantage of technological advances that make data centres simpler, more efficient, easier to manage, and more cost-effective to operate. As IT demands change and infrastructure ages, the

opportunity to get significant benefits from modernisation exists.
As physical infrastructure systems approach
end-of-life, the risk of downtime increases. The options for data centre managers are either to modernise or outsource business functions to cloud or colocation service providers. There are three key domains that must be addressed when considering modernising your data centre: equipment hardware (electrical and mechanical), software management systems, and operations and maintenance programs. In this post, we will focus on uninterruptible power supplies (UPSs).
Rightsizing your data centre UPS Much like replacing an old furnace in your house, upgrading your data centre’s UPS(s) can provide not only increased reliability, but also increased efficiency and cost savings. Data centre workloads (and therefore capacity needs) of 10 years ago are likely to be very different than today. They may have increased or decreased substantially based on a variety of factors, including mergers and acquisitions that boost the workload, virtualisation technologies that reduce the physical server footprint, and cloud migration, which enables companies to
