Hyperscale Hyperscale data centres have an incredibly scalable computing architecture which can be managed like a single unit. Hyperscale solutions allow CIOs to start out modestly with lower investments and react to growing demand. They can thus immediately aggregate or extend their networks smoothly without having to interrupt operations. Hyperscale capability is based in particular on there being an available mass of optical fibres. High count fibre cables with more than 2000 or 4000 multi fibre cables are typically needed to cover the connectivity requirement. Fibre Vs. copper That being said, copper is still a good option for horizontal links (10G) and with the new Cat. 8, it will be able to provide 40G for 30 metres. So, it remains cheaper and sufficient for small distances. Density and modularity With internal data centre traffic expected to grow by 80% over the next three years, there is a real risk of networks becoming bandwidth bottlenecks. By moving from traditional low-density cabling to high-density structured cable solutions, CIOs can implement physical network infrastructure in a far more flexible manner. These systems enable data centres to easily migrate to 25, 40 and 100 Gb/s networks and solve some critical network challenges. Automation Automation benefits servers, storage and switches, but the cabling that interconnects it all largely remains a cumbersome, manual, error-prone management mess. For this reason, over the last several years, Automated Infrastructure Management (AIM) has become a strategic investment for optimising resource usage and cabling documentation in data centres. AIM eliminates stranded capacity, facilitates end-to-end analysis and agile infrastructure management and aids predictive analysis and dynamic infrastructure. Not only this, these solutions improve the efficiency of operation and administration and can result in reduction of downtime by 30% to 50%. ◊ No one asks for a slower network and while it is 10GbE that is being deployed, all new implementations are factoring in the need to include easy 40G and even 100G migration as a part of their future. And for this, higher value cabling systems such as fibre is the way forward. Fibre systems facilitate the set-up of high-density cabling systems for data networks with parallel-optical connection technology. Consequently, data centres can introduce 10 Gigabit Ethernet (GbE) or even 40 and 100 GbE as a bandwidth to connect the fastest servers and switches to each other. 58 Issue 08 www.intelligentdatacentres.com
