Bridging the data deluge gap--the role of smart silicon in networks
The proliferation of smart mobile devices, video, user-generated content and social networking, and the rising adoption of cloud services for both enterprise and consumer services are all driving explosive growth of wireless networking infrastructure.Globally, mobile data traffic is expected to grow 18-fold between 2011 and 2016, reaching 10.8 exabytes per month by 2016. Today, video traffic alone accounts for 40 percent of the wireless network load.The number of mobile devices connected to wireless networks will reach 25 billion, averaging 3.5 devices for every person on the planet, by 2015.That number is expected to double, to 50 billion, by 2020. This growth in storage capacity and network traffic is far outstripping the infrastructure build-out required to support it, a phenomenon known as the data deluge gap.
The bridging of the data deluge gap.
To bridge this gap, the industry needs to leverage smarter silicon technology to scale data center infrastructures more cost effectively.Besides helping close the data deluge gap, smarter data processing offers potential dramatic improvements in application performance.A recent survey of 412 European data center managers conducted by LSI revealed that while 93 percent acknowledged the critical importance of improving application performance, a full 75% do not feel that they are achieving the desired results. This indicates that there is rising pressure on data center managers to find smarter ways to push systems to do much more work within the same power and cost profiles.Smart software running on general-purpose processors, increasingly with multiple cores, is pervasive in the data center.General Purpose Processors have long inhabited switches and routers, firewalls and load-balancers, WAN accelerators and VPN gateways.None of these systems are fast enough, however, to keep pace with the data deluge on its own, for a basic reason: general-purpose processors must treat every byte equally. While such equality is perfectly acceptable for system-level versatility, it is inadequate for low-level, high-volume packet processing.
Accelerating networks
In many organizations today, microseconds matter, driving strong demand for faster response times.For trading firms, latency can be measured in millions of dollars per millisecond.For others, such as online retailers, every millisecond of delay can mean lost sales and fading customer loyalty.Tomorrow’s data center networks will need to be both faster and flatter,and therefore, smarter than ever.To eliminate the data deluge gap and maximize performance,systems need to be smarter,and those smarts will increasingly need to take the form of purpose-built silicon.
Future predictions
Baseband chips, already accounting for more than half the revenue of the total handset core IC space, will maintain their pre-eminence in determining the market-share gains and losses of industry vendors moving forward, IHS said.But the future will also be driven by the ability of any given IC supplier to provide platform solutions that optimize the system-level design of all of the ICs, making up the handset’s core chip architecture, the firm predicted.
