Common Factors for IT venue selection (Choosing In-house or Outsource)

Data center capacity is rapidly expanding in outsourced, third-party IT venues, such as colocation data centers and public cloud. Whether measured in megawatts (MW) of uninterruptible power supply capacity or IT load (or by some other measure, such as square feet of white or leased space, or in units of compute or storage) overall capacity […]

Why ASHRAE is concerned about edge data centers

There are few organizations that have had as big an impact on data center design as ASHRAE — and specifically, their Technical Committee (TC) 9.9. ASHRAE’s 2004 publication Thermal guidelines for Data Processing Environments (now in its fourth edition) described the optimal environmental operating conditions for the electronics in a data center, and in doing so, effectively […]

PUE: The golden metric is looking rusty

When the PUE (power usage effectiveness) metric was first discussed at a meeting of The Green Grid in Santa Clara, back in 2007, a microphone stand was placed in each aisle of the auditorium. The importance of the initiative was understood even then: experts, including the founders of Uptime Institute, formed lines to give their […]

Will the pandemic accelerate the move to public cloud?

As the COVID-19 pandemic has unfolded, many people have suggested that the business case for enterprises to move more workloads to the public cloud has been strengthened. Some have argued that the pandemic will accelerate the decline of the enterprise data center. Is this actually the case? And if so, why? This is one of […]

Data Centers and Wildfires

As will be discussed in our upcoming note about managing data center with the severe weather caused by climate change, we continue to highlight the need for data center managers to not only review existing emergency plans but also anticipate previously unforeseen challenges. The need to understand the new ‘Normal’ Which brings us to wildfires… […]

Pandemics: Operators plan to be ready next time

Data center managers, on both the facilities and the IT side of operations, are known for their preparedness. Even so, the pandemic caught most by surprise. Few had an effective pandemic plan in place, and most had to react and adapt on the fly, as best as they could. A small but significant number suffered […]

Lithium-ion batteries in the Data Center: An ethical dimension?

One of the emerging trends in data centers is the use of lithium ion (Li-ion) batteries, both for distributed and centralized uninterruptible power supplies. Research by Uptime Institute and others predicts high levels of adoption in the years ahead. The primary reasons for this are technical, relating to energy density, rechargeability and management. But Li-ion […]

Humidity and COVID-19 in data centers

Data center managers have gone to some lengths to avoid transmission of the COVID-19 virus in their facilities. Fortunately, many factors help keep transmission rates low in data centers: few staff are required; most jobs do not require close physical interaction with colleagues; and air filtration may help to reduce, if not necessarily eliminate, airborne […]
