A recent BSRIA survey shows that the uptake of Top of Rack (ToR) is significantly higher in colocation data centres than in enterprise data centres. - 61% of the colocation data centres have opted for ToR compared to 42% of the enterprise data centres.
Around 19% of the global market for structured cabling is installed in data centres with the remaining 81% being deployed in LAN applications. The structured cabling installed in data centres, based on BSRIA’s yearly research, is estimated at $1.2 billion in 2014. The data centre segment is expected to continue its increase with huge demand for back-up data, video storage, peer-to-peer file sharing, cloud computing and the uptake of the Internet of Things (IoT) with numerous devices being connected in future.
BSRIA’s new Global Data Centre report covers 5 countries (US, UK, Germany, China and Brazil), which combined account for approximately 68% of worldwide DC cabling.
The report is published in two parts:
The increasing use of higher speed and the media used is one of the topics covered in the end-user survey.
The study highlighted quite significant levels of 1G and 10G both in switch-to-switch and switch-to-server links and expected progression to 40G and 100G planned for 2016.
The uptake of ToR is higher for the colocation segment at 61% than for the enterprise segment, with 42% opting for ToR. A third of the enterprise data centres use centralised switching.
The end-users were asked about their use of media for future 10G links. The usage of non-structured cabling P-P link was significant higher for the colocation segment, which also has a higher usage of ToR architecture.
Of the end users who were planning to upgrade to 10G links, 33% of enterprise data centre end-users were planning to do so in 2014. Among the colocation data centres, this percentage was much higher, 67% of end-users had plans for a 10G upgrade in 2014.
The main reasons for the use of Point-to- Point links have remained largely unchanged from 2011.
The typical replacement rates are very similar for copper and fibre cable and connectivity. Around a quarter replace the cabling every 4 – 5 years and around 15% every 8 – 10 years. A significant proportion do not replace the cabling.
Outsourcing is expected to increase globally and across all sectors. The survey suggested that outsourcing is considered in 50% of Data Centres which is in line with the forecast results of the BSRIA study completed in 2011. It is expected that outsourcing will grow further by up to 60% by the end of 2016.
