Just a few years ago, most data centers were running 1 Gb/s and 10 Gb/s, which seemed incredibly fast.
Today, 10 Gb/s is the standard and 40 Gb/s and 100 Gb/s are on the horizon, but coming fast. What is driving these changes? Perhaps the most pressing driver is the expectation to access business and entertainment services that require high data rates from anywhere and at any time. And there is a lot of data. Internet use, tweets, security, IoT, hyper-convergence, software-defined infrastructure — these are just some of the industry trends driving increases in data. Estimates put annual data generation at 35 trillion TB of data yearly by 2020.
