34 TEST & MEASUREMENT Testing times for the data centre By Amie Cox PhD, Global ICP Sales Leader, Viavi Solutions www.viavisolutions.com What problems are enterprises likely to face as they evolve their data centres? The technology titans: Alphabet, Amazon, Apple, Facebook and Microsoft are transforming the data centre. Content is driving network traffic growth at breakneck pace – and data centres are at the epicentre of this trend. According to a recent study from Cisco, network traffic will grow to 15 zettabytes by 2020 with a CAGR of over 27%. As new technologies and applications come online, traffic volumes will only intensify and could even surpass these estimates over the next two to three years. Along with this data growth, data centre managers also face challenges such as interoperability, complex multifibre infrastructure and rising costs. Changes are afoot that require a new mindset in the realm of test and measurement to ensure 24/7uptime. For operators, the network is their product and they conduct extensive tests – and more tests – almost every time they introduce a new service. Internet Content Providers (ICPs) have a different mindset. Their product is content and the network is the vehicle to reach the user. Often ICPs conduct limited tests prior to the launch of a new service – they find it time consuming and a constraint on the pace of their growth. Understanding the ICP mindset and its impact on network infrastructure, along with their requirements, is fundamental to the continued expansion of data centres. Increasing automation Usually, telecom operators have hundreds of engineers to manage the network and most are hardware proficient. They consider the lifespan of hardware and technology to be around 10+ years. ICPs, on the other hand, have much smaller operations teams and their forte is typically routing and software. As such, they create open Application Programming Interfaces (APIs) and software-based automation to maximise workloads and networks. What’s more, the phenomenal growth rate of ICP infrastructure requires them to rip out and replace technology every three to five years, so they view hardware with a limited lifespan. ICPs often find that the standards bodies move too slowly to meet the needs of their business TS IT - Network Rack Make IT fast ....Make IT simple ....Make IT adapta ....Make IT ea ENCLOSURES POWER DISTRIBUTION CLIMATE CONTROL
