The Three Things Next-Generation Data Centers Need from Networking

By Amit Sanyal, Senior Director, Product Marketing, Marvell

Data centers are arguably the most important buildings in the world. Virtually everything we do—from ordinary business transactions to keeping in touch with relatives and friends—is accomplished, or at least assisted, by racks of equipment in large, low-slung facilities.

And whether they know it or not, your family and friends are causing data center operators to spend more money. But it’s for a good cause: it allows your family and friends (and you) to continue their voracious consumption, purchasing and sharing of every kind of content—via the cloud.

Of course, it’s not only the personal habits of your family and friends that are causing operators to spend. The enterprise is equally responsible. They’re collecting data like never before, storing it in data lakes and applying analytics and machine learning tools—both to improve user experience, via recommendations, for example, and to process and analyze that data for economic gain. This is on top of the relentless, expanding adoption of cloud services.

Low Power DSP-Based Transceivers for Data Center Optical Fiber Communications

By Radha Nagarajan, SVP and CTO, Optical and Copper Connectivity Business Group

As the volume of global data continues to grow exponentially, data center operators often confront a frustrating challenge: how to process a rising tsunami of terabytes within the limits of their facility’s electrical power supply – a constraint imposed by the physical capacity of the cables that bring electric power from the grid into their data center.

Fortunately, recent innovations in optical transmission technology – specifically, in the design of optical transceivers – have yielded tremendous gains in energy efficiency, which frees up electric power for more valuable computational work.

Recently, at the invitation of the Institute of Electrical and Electronics Engineers, my Marvell  colleagues Ilya Lyubomirsky, Oscar Agazzi and I published a paper detailing these technological breakthroughs, titled Low Power DSP-based Transceivers for Data Center Optical Fiber Communications.

Why the 100G Optical Module Transformation is Full Steam Ahead

By Rohan Gandhi, Product Marketing Manager, Optical and Copper Connectivity

When the London Underground opened its first line in 1863, a group of doubtful dignitaries boarded a lurching, smoke-belching train for history’s inaugural subway ride. The next day, thirty thousand curious Londoners flooded the nascent system, and within a year, more than nine million had embraced its use. Nearly 160 years later, that original tunnel is still in daily use, joining 250 miles of track that carry more than 1.3 billion passengers annually.

What were the keys to such extraordinary growth? Not just popular demand for more tunnels, but also better use of accumulated infrastructure – optimized through newer trains, enhanced signaling, greater energy efficiency, and smarter scheduling. In a sense, the Tube’s transformation mirrors the fundamental challenge now confronting modern data centers: how to make better use of existing infrastructure to handle today’s exponential growth of data.

PAM4 DSP Technology is Fast and Flexible

To keep up with the surging data demands of new video and AI workloads, modern data centers can’t simply add more and bigger pipes – at least not cost-effectively. They need PAM4 based optical module solutions to effectively and efficiently move more bandwidth at higher speeds. In addition, they need to be able to update the optical modules via software, optimizing existing infrastructure at an affordable price.

Highly Integrated Silicon Photonics Light Engines in High-Speed Data Transport

By Radha Nagarajan, SVP and CTO, Optical and Copper Connectivity Business Group

The exponential increase in bandwidth demand will drive continuous innovation in, and deployment of, data movement interconnects for Cloud and Telecom providers.  As a result, highly integrated silicon photonics platform solutions are expected to become a key enabling technology for the cloud and telecom market over the next decade.

What Does Highly Integrated Silicon Photonics Platform Mean for the Infrastructure Business?

As speed continues to go up, optical will replace copper as the primary conduit of the digital bits inside Cloud data centers.  Marvell is investing heavily in silicon photonics to complement our high-speed CMOS technologies in data center interconnects to accelerate this transition.

  • Silicon photonic solutions have been successfully deployed inside Cloud data centers for 100G to compete with traditional “chip-and-wire” discrete solutions.  We expect silicon photonics will gain market share as the Cloud providers transition to the next bit rate of 400G.
  • Integrated silicon photonics platform solutions have intrinsic advantage over conventional packaging solutions at ever increasing baud rates.
  • Hyperscale data centers have limited power and cooling available for severs and interconnects. Integration technology is attractive where space and power savings are critical.
  • Integrating optical components on a silicon interposer can leverage the cost benefits of large-scale automated electronics assembly eco-system versus the traditional “chip-and-wire” optical industry.
