Converting IT Closets into Edge Computing Sites
The year was 1968. My father was holding what looked like a black suitcase with two white stripes. He handed it to me and said “Here’s a gift for you. Your first record player!”. For years, I played records on that turntable (“Hey Jude” by the Beatles was the first “single” I ever owned). Eventually, that portable record player found its way to the closet as new formats for music were released to the marketplace.
Today, the data centre industry finds itself undergoing changes just as radical as what has occurred within the music industry. Just as CDs replaced vinyl records, and music downloads have, even more quickly, replaced CDs, older wiring closets and makeshift server rooms are being radically transformed.
For consumers of music, a need for convenience and mobile access to songs drove these changes (why bring a pile of scratched records to the party if pushing one button on your mobile phone grants you access to your preferred playlist, without the snap, crackle, pop and skips)? For IT staffs. the spaces dedicated to two-post racks and cables need to be optimized and repurposed to serve the performance needs of bandwidth-hungry end users.
The drive for IT closet space optimization involves both the need for local computing sites to aggregate and store local data in order to provide “edge” users with faster and easier ways to access information, and the need for IT staffs to beef up remote management services. The new, affordable remote services run on cloud-based platforms and offer benefits such as data analytics, reduced downtime, reduced operations overhead, and improved energy efficiency for power and cooling systems.
As we enter a new phase in the way IT staffs support local users, confusion exists regarding the differences between old school IT closets and modern Edge Computing sites. Just like vinyl records and downloads both produce music, the way the final product (in this case data and information) gets produced, delivered and consumed requires rethinking.
Below are highlights of some of the critical differences between traditional IT closets and modern Edge Computing sites:
· Uptime expectations – According to industry estimates, some 2.9 million IT closets (small server rooms and wiring closets) exist in the United States alone and over 70% report outages directly attributed to human error. Many of these IT closet facilities are unattended IT rooms that are minimally supervised. In most cases, operators and administrators have trouble preventing the human error from occurring in these environments. For example, cleaning staff can walk in and unwittingly disconnect a cable. In edge environments, remote monitoring and automation software can be integrated with video surveillance and sensors to reduce the occurrence of human error-related downtime. Racks and enclosures are preconfigured to include integrated power and cooling, cable management, monitoring and management software, cybersecurity, physical security (like remotely controlled rack locks), intelligent rack outlets and sensor technology.
· Power infrastructure – Most wiring closets have little, if any uninterruptible power available. In fact, the legacy wiring closet, which used to house passive devices like patch panels and hubs will now need to evolve to accommodate high power switches, higher density servers, routers and Uninterruptible Power Supplies (UPS) with longer runtimes.
· Cooling configurations – The cooling of IT wiring closets is rarely planned and typically only implemented after failures or overheating occurs. Because the power density of IT equipment has increased over time, distributed IT equipment such as routers, switches or servers overheat more often and fail prematurely due to inadequate cooling. In new edge environments, solutions such as the Schneider Electric Micro Data Centre have been designed to assure cooling compatibility with anticipated loads. Oversizing is avoided so that electrical efficiency is maximized. Footprint options are flexible enough to work in spaces of various shapes and sizes, including closet-like spaces.
As vinyl records begin to fade from the memories of most consumers (except for hard core vinyl lovers), so will legacy IT closets.
