Cloud Computing: Closer to the Edge Data Center

Grazed from DataCenterJournal. Author: Dr. Thomas Wellinger.

Away from urban areas, high-bandwidth applications (mobile computing, HD video, cloud...) can suffer. Data centers on the ‘edge’ of the internet, away from traditional hubs, can help. Large volumes of popular content and applications (like Netflix series) are cached on servers closer to less densely networked ‘tier-two’ markets. There are a few things to consider, when specifying and building an edge data center.

First, there are space constraints. Cabling from servers often directly connects to a fibre platform in a central network cabinet. The fibres have to accommodate twisting and cable moves, adds and changes. Data has to move through cables at awkward angles without quality loss. Network cabinets need lots of space for switches...

Meeting future data center needs

An edge network may have to support several generations of hardware and bandwidth standards. High density – over 100 ports per rack unit - is essential. Traditional solutions based on 72 ports per unit won’t suffice. Ideally, all fibres should go directly from server ports to a Ultra High Density platform that handles up to 50% more fibre optic connections in a traditional housing. Cables should have a very high fiber count. However, it is important that they can be handled the same way as smaller cables. Termination must be as easy as possible...
