Cabinet airflow management done right
By Hans Vreeburg – Let’s start with some basic understanding of airflows within data centers. Nowadays almost all data centers apply hot and cold corridors to optimize the cooling capabilities. In the ideal situation cold air goes straight to the servers’ inlets. The hot air exiting the servers is returned directly to the cooling unit. This setup enables systems to run at the highest possible efficiency, using the least amount of power. The cooling setup has a big influence on the PUE (Power Usage Effectiveness): a lower PUE results in lower total energy consumption of the data center. This indirectly saves the environment and lowers OPEX costs. Could a small gap in your server rack really have that much influence?
As said above, the ideal setup is cold air entering the servers, while hot air exits. Gaps can lead to a higher demand of cold air than actually required by the servers. See it as a large water pipe: it normally needs a specific amount of water. When we make some holes in the pipe, you will need to pump in more water to get the same amount at the end of the pipe. more>
datacenter.com – Cloud direct connect allows enterprises to access public cloud services (i.e. Amazon, Google, Microsoft, TencentCloud, etc) over a dedicated, private connection rather than over the public Internet. The benefits of direct cloud connections to your own network include greater reliability, better performance (better speed, lower latencies) and a higher security than typical connections over the Internet.
The costs of WAN and public Internet connectivity can be significant. The cost of moving a lot of data to your cloud provider vary per provider, but often are expensive. By using a neutral data center, you have access to multiple carriers who can provide you the necessary public Internet connections and direct cloud connect services. By segmenting the various network workloads, you can often realize savings in bandwidth and reduce the costs of moving data to your public cloud provider.
By replacing a “best effort” network, such as the public Internet with a direct connection to your cloud provider, you gain consistency in throughput and performance. As the mathematical principle states, “the shortest distance between two points is a line.” By using cloud direct connect services you’re connecting to the cloud provider in a straight line and increasing your performance. more>

12 Mind-Blowing Data Center Facts You Need to Know
Ciena – How big has the data center monster become? Here are 12 fascinating facts about data centers that just may blow your mind.
- There are over 7,500 data centers worldwide, with over 2,600 in the top 20 global cities alone, and data center construction will grow 21% per year through 2018.
- By 2020, at least 1/3 of all data will pass through the cloud.
- With just over 300 locations (337 to be exact), London, England has the largest concentration of data centers in any given city across the globe.
- California has the largest concentration of data centers in the U.S. with just over 300 locations.

By Dave Bursky – The purchase of field-programmable gate array (FPGA) supplier Altera by Intel® in 2015 surprised many companies in the electronics industry. And now that Altera is integrated into Intel, everyone is concerned about the future of the Altera programmable products and what direction Intel will take to leverage the configurable technology.
During his keynote presentation Intel CEO Brian Krzanich covered two major issues on the top of all attendees’ minds.
First, he promised to keep the existing FPGAs with ARM cores and not replace the cores with x86 compatible cores. And, second, he gave a short look at the future roadmap for the FPGAs, which include system-on-a-chip solutions that combine the i86 cores and FPGA fabric, initially in the same package and eventually on the same chip. In these future products he indicated that x86 cores would play a significant role.
Further integration of the CPU and FPGA fabrics can reduce system complexity and bring the processing closer to memory to achieve higher performance by reducing latency (Figure 1b). Such a future data center design would also benefit since the integration would reduce power consumption and reduce the board area required. CPUs such as the Intel® Xeon® or Xeon® Phi™ would work side by side with FPGAs such as the Cyclone or Arria 10. more> https://goo.gl/iqEoTO
By Jon Gold – The tech world has long speculated on the amount of computing power that it must take to run a network of web services as titanic as Google’s, but the company has always been famously paranoid about preserving the secrecy of its facilities – until now. The search giant has just released an illuminating series of photographs from within its data centers. more> http://tinyurl.com/8rfxm85

By Jim Duffy – Alcatel-Lucent this week at Interop will flesh out its data center fabric vision with 40G Ethernetand higher-density 10G Ethernet capabilities on its core switches, as well as enhanced software for its top-of-rack and core switches.
The extensions to Alcatel-Lucent‘s Application Fluent Networking (AFN) strategy are intended to offer users a low latency, multipath network with which to establish multi-site private clouds and connect to public clouds offered by service providers. In this endeavor, Alcatel-Lucent’s AFN will go up against fabrics like Cisco‘s FabricPath and CloudVerse, Juniper’s QFabric, Brocade’s Brocade One and Cloudplex, and HP’s FlexNetwork. more> http://tinyurl.com/ch7md5q

By Jim Duffy – Despite vendor pledges to support existing or developing industry standards, users are expected to deploy single-vendor data center and cloud switching fabrics from their primary suppliers.
Standards such as Transparent Interconnect of Lots of Links (TRILL), Shortest Path Bridging and Multi-Chassis Link Aggregation will be embraced by those vendors looking to dent Cisco‘s dominance in data center switching.
The standards support will soothe customers looking to avoid vendor lock-in, but it’s unlikely IT shops will mix and match multivendor switches within and between data centers. more> http://is.gd/yxxBJY

Jaymie Scotto & Associates – 2012 Telecom Exchange will be held June 27th at Cipriani Wall Street in Manhattan.
Telecom Exchange is an annual industry networking event designed to increase delegates’ ROI by offering face-to-face meetings and a neutral, exhibit hall environment. The event is attended by the data center and colocation facility operators as well as the local and global network operators that have connectivity within these key facilities. Telecom Exchange offers a directory and an online meeting system, DealCenter, to help navigate attendees to other network operators who are one cross-connect away from doing business. All meetings pre-planned through the DealCenter are held on-site at Telecom Exchange.
“The combination of the neutral exhibitor floor and one-on-one meetings provides equal opportunities for small and large companies, ” states Jaymie Scotto Cutaia, CEO and Founder of Jaymie Scotto & Associates and DealCenter, LLC. “With the support of DealCenter, an online system that lists and sorts attendees by name, company, service, and available interconnection points, Telecom Exchange empowers participants to focus on generating qualified business opportunities.”
Sponsorship and exhibit opportunities are still available, on a first-come, first-serve basis. To learn more about sponsorship packages and exhibition space, contact Lauren Sauer at firstname.lastname@example.org or visit www.thetelecomexchange.com. ™¦

IBM has installed the first iteration of the system on the 6,000 square-feet of rooftop of its India Software Lab in Bangalore. The solar array is capable of providing a 50-kilowatt supply of electricity for up to 330 days a year, for an average of five hours a day. more> http://is.gd/aqflT9

By Jim Duffy – The past three years have been very noisy on the data center fabric and architecture front. Every quarter seems to bring about a new convergence blueprint from another vendor – and a variety from one or two.
Fibre Channel over Ethernet (FCoE) is being pushed hard by Cisco. It consolidates server adapter ports by tunneling FCoE instead of requiring a separate Fibre Channel network.
Brocade has some FCoE products but is not as bullish as Cisco on the technology. That’s because Brocade has the lion’s share of the Fibre Channel SAN market – it would lose Fibre Channel revenue to Cisco.
Juniper‘s QFabric seeks to flatten and simplify data center networks to accommodate growth of devices and applications, virtualized servers and storage, and cloud-enabled on-demand access to virtualized pools of IT resources. more> http://is.gd/MkPxbw
