Reducing IT’s Carbon Footprint via Tape While Improving Cybersecurity and Protecting the Bottom Line

There is increasing pressure around the world to reduce emissions and lower mankind’s carbon footprint. It is up to the IT sector to do its part, and that means considerably lowering power usage. But that is easier said than done when you consider the statistics.
IDC predicts we will arrive at the mind-boggling figure of 175 zettabytes of data in the digital universe within 4 years. 175 ZB? Consider how long it takes most users to fill a one TB drive. Well, 175 ZB equates to approximately 175 billion TB drives.
The problem is this: how do you reduce IT’s overall power draw in the face of a massive and continual upsurge in data storage? Once 175 ZB of data exists, there is no possibility of containing electrical usage if the vast majority of storage is sitting on hard disk drives (HDDs). The only solution is to cure the industry’s addiction to disk.
Here are the numbers. Data centers alone account for close to 2% of all power consumed in the U.S., about 73 billion kilowatt hours (kWh) in 2020. That is enough to set off the alarm bells. Yet tremendous progress has been made over the past two decades in terms of data center efficiency. When power consumption in data centers soared by 90% between 2000 and 2005 period, the industry acted forcefully. The rate of growth slowed to 24% between 2005 and 2010 and then fell to less than 5% for the entire decade between 2010 and 2020. That’s miraculous when you consider that it was achieved during a period that represented the largest surge in storage growth in history. Smartphones, streaming video, texting, multi-core processors, analytics, the Internet of Things (IoT), cloud storage, big data, and other IT innovations demanded the retention of more and more data.
Big strides were made in Power Usage Effectiveness (PUE – the ratio of data center power consumption divided by the power usage). Data centers have largely done a good job in improving the efficiency of their operations. But the one area lagging badly behind is storage efficiency.
