cabling, Enclosures, Cabinets & Racks A CHANGING LANDSCAPE Lee Griffiths, alliance manager, EMEA, APC by Schneider Electric, explains why digitalisation and the IoT require a forward thinking approach for reliabilty, security and delivery of business critical IT services. I t’s no secret that racks and enclosures are the building blocks of every IT environment. As companies move to take strategic advantage of trends like digitalisation, cloud computing, hyperconvergence and the growth of the Internet of Things (IoT), we continue to see an increase in the adoption of virtualised applications, which are in turn changing the landscape of data centres. Digitalisation is, for example, fueling the growth of business critical applications being deployed in localised data centres. The result is a hybrid environment, which depends on a secure, connected infrastructure chain consisting of centralised facilities, cloud computing services and single rack micro data centres distributed at the edge of networks. Indeed, many data centres that were once home to a multitude of rack enclosures may now only consist of a single rack solution; hosting critical IT equipment and providing secure network connectivity to the cloud. And with the inevitable increase in data traffic produced by connected devices, there is now a growing requirement for data centre physical infrastructure to be located closer to the source of data. Resiliency Whether deployed inside a network closet, a secure server room, or as a single micro data centre, on-premise IT operations rely on 34 | April 2017 racks and enclosures for support, organisation and management of the IT chain. With the increase of connected devices, today’s racks and enclosures are expected to support a greater number of connections and greater variety of applications, which also has implications for the overall levels of security and resilience required. It is largely accepted that centralised data centres have the highest standards of physical security, environmental monitoring, management systems, data recovery and back up power. This is because typically, these facilities have redundancy in their critical power and cooling systems to avoid failure or downtime. Physical security measures often include on site security personnel, as well as biometric sensors, video surveillance and critical entry points to ensure that only authorised personnel gain access to sensitive areas. Racks containing IT equipment are often locked and power and networking cables organised to reduce opportunities for human error. But further down the chain, in unsecured network closets for example, we won’t always find the same level of resiliency. Micro data centres With the increase of connected devices, today’s racks and enclosures are expected to support a greater number of connections and greater variety of applications. Micro data centres are often colocated with their users, in rooms which can be unsecured with racks that are unorganised. Older network enclosures may be open to a greater number of people, and cable management is less stringent with cable clutter and obstructions Ñ¼…¥É™±½Ü)ݥѡ¥¸É…­ÌƒŠL±•…‘¥¹œÑ¼½½±¥¹œ)Áɽ‰±•µÌƒŠL…¹¥¹É•…Í•¡Õµ…¸)•Éɽȸ%¸ÍՍ …͕́ѡ•É”µ…䁉”)±¥Ñѱ”É•‘Õ¹‘…¹ä¥¸Ñ¡”É¥Ñ¥…°)Á½Ý•È…¹½½±¥¹œÍåÍѕµÌ°½È)¥¹‘••µ½¹¥Ñ½É¥¹œ‰äÍÁ•¥…±¥ÍÐ)‘…Ñ„•¹Ñɔ)¥¹™É…ÍÑÉՍÑÕɔ)µ…¹…•µ•¹Ð(¡ %4¤½È)¹•Ñݽɬ)µ…¹…•µ•¹Ð)ͽ™Ñ݅ɔ¸
