Posts about DCI

The data center interconnect (DCI) is emerging as a key element in the enterprise strategy to transition to a more digital-oriented business model, one that encompasses multiple data processing and storage sites on the cloud and the IoT edge. At the same time, however, static network connectivity both within the data center and over the wide area is becoming increasingly virtualized and software-defined, meaning that in the very near future organizations will take to managing and optimizing their DCI infrastructure as code ...

The first few months of 2018 has led to great leaps in the US cloud hyperscalers in terms of deployments and testing of next-generation solutions, such as 400Gbit/s. However, Chinese hyperscalers are building their infrastructure with notable differences, some of which are materializing in the type of equipment being deployed. While this has often been attributed to a technological gap with Western cloud providers, I believe some of the difference is actually driven by physical limitations of the cloud in China. Three major differences have emerged in the past six months ...

The enterprise’s insatiable demand for bandwidth shows no signs of letting up any time soon. In fact, if current trends continue, it’s about to expand dramatically both inside the data center and on wide area infrastructure. But adding bandwidth is not simply a matter of widening the pipe. More bandwidth means more complexity, faster throughput and improved layering and segmentation to accommodate workloads of various types and sizes. And it all has to be done with an eye toward the future so you don’t end up repeating the process a few short years from now ...

400Gbit/s products for the data center made significant strides at both the OFC and OCP show compared to what was shown just a year ago. During the first few months of 2017, 400Gbit/s became a popular topic for data center networking, but many of the demos were limited in nature with test board demos instead of working products. In 2018, that changed significantly, the technology matured and demonstrations of working products were abundant. We saw multiple system and component vendors demonstrating working systems based on 56Gbit/s SERDES and real optics ...

The colocation market continues to expand rapidly, driven by a wide range of customers, including hyperscalers, enterprises, telco service providers, cable MSOs, and the Tier 2/3 cloud. In 2017, enterprises moved in significant quantities over to colocation providers in order to have better access to their peers, direct connect to the cloud, flexibility, and to move the non-core expertise of designing and building data centers to someone else ...
