6 Essential Data Center White Papers

November 30, 2011 at 10:00 am PST

I spoke at my son’s school for Career Day a couple of years ago.  I talked about my time as a newspaper reporter and basic news writing principles such as the five Ws, attribution and the inverted pyramid.  There’s a chance I’ll return this year to talk about being a Data Center manager, which has me pondering what Data Center basics to cover.

If you had to explain Data Center fundamentals to a newcomer, what would you talk about?  Availability?  Power density?  The fact that everything people do online is enabled by a Data Center somewhere?

Part 3 – Cisco IT on Cisco Intelligent Automation – @ Gartner Data Center Conference, London

November 30, 2011 at 2:39 am PST

London's Big Ben at Night

Following on from my introductions to what is happening at this data center conference see part 1 and part 2), in this article I’ll talk more about something I’ve not really blogged about in my previous blogs (which is surprising given my NMS background) - data center management and Cisco Intelligent Automation.   I managed to catch up with a senior manager in the Cisco IT team, Rich Gore, who game me some terrific insight into their deployment of Cisco Intelligent automation.   And I’ll also relate some experience of my own on why, when it comes to the products you produce, you should always (as the US folks tend to say) “eat your own dog food”!

Cisco Introduces Global Cloud Index

Cisco today announced its inaugural Global Cloud Index (2010-2015)-- research that forecasts, among other topics, that Global Cloud Computing Traffic will Reach 1.6 Zettabytes by 2015 and Global Cloud Traffic Will Exceed One-Third of All Data Center Traffic by 2015. This analysis was undertaken by the same team that presents the Visual Networking Index (VNI).

Just in time for the holidays: cloud data!

With the emergence of cloud computing, our customers have looked for real-world data that could help them understand the nature and scope of the cloud phenomenon. But that kind of data has not been readily available.

Not satisfied with this lack of information, a research team at Cisco reviewed 30Tb of data each month, more than 45 million speed tests, analyst forecasts, and inputs from our customers.  The result?

Today, Cisco released its first Cisco Global Cloud Index report — a forecast of IP data center and cloud-based traffic growth and trends worldwide, 2010-2015.

Similar to the Cisco Visual Networking Index in purpose and approach, the Global Cloud Index enables organizations to make strategic networking and management decisions and governments to make informed public policy decisions.

Some highlights from the report reveal: (all data global)

1.    Cloud traffic is growing twice as fast as data center traffic, increasing from 130 exabytes in 2010 to 1.6 zettabytes annually by 2015

  • 1.6 zettabytes is approximately equivalent to 22 trillion hours of streaming music
  • 76% of this traffic will remain within the data center itself
  • By 2015, 57% of all data workloads will be processed in the cloud Read More »

Networking Forecast: Cloudy with Increasing Zettabytes

With the onset of cloud, we’re being asked more and more by our customers about the architectural requirements that result from it.  While the customers have an instinct as to what’s needed, there seems to be less actual data to that effect than what they would like.  When confronted with a similar situation over 5 years ago about the network, we developed the Cisco Visual Networking Index which focuses on the amount of traffic carried across the network to the end user to help gauge the extent of infrastructure needed to support the data deluge.  Now with the network becoming inextricably linked to the data center and cloud, we realized we need to look at the other half of the equation as well to get a truly comprehensive architectural view.  To achieve this, we reviewed 30Tb of data each month, more than 45 million speed tests, analyst forecasts, and inputs from our customers.  The result?  The inaugural Cisco Global Cloud Index, released today.

Here are a few takeaways to consider:

  • Global data center traffic is estimated to grow four-fold to reaching a total of 4.8 zettabytes annually by 2015.
  • The vast majority of the traffic – 76% — surprisingly, doesn’t even hit the network but instead stays within the data center itself, as workloads are constantly being migrated to different virtual servers.
  • Of the total data center traffic, about 11%, or 130 exabytes of annual data center traffic in 2010 is considered part of the cloud  – however that amount is going to grow significantly in the next half decade, reaching more than a third of data center traffic, or 1.6 zettabytes annually, by 2015.

Cloud may be the concept-of-the-day for the industry, but with growth like that, it shouldn’t be discounted as a passing fad but rather a lasting trend whose impact will fundamentally affect network architectures going forward. Read More »
