Introduction

The data center landscape for many organizations is constantly changing with the introduction of new technologies and economic drivers. Several technologies have been at the forefront of the planning and implementation efforts of many IT professionals that contribute to increases in network bandwidth and performance. Virtualization continues to be a major technology being implemented in data centers to help maximize usage of hardware resources in computing, storage and networking environments. Technologies like cloud computing and the Internet of Things (IoT) rely heavily on available network resources in order to fulfill their operations. On the economic side, fluctuations in the economy and tighter restrictions on spending has led to additional constraints on IT organizations such as showing a measureable return on investment (ROI) and combating dwindling space, power, and cooling resources in data centers.

25G technology

In 2014, the 25G Ethernet Consortium released a specification that enabled data center networks to run over a 25 Gigabit per second (Gbps) Ethernet Link protocol. Then, in 2016, the Institute of Electrical and Electronics Engineers (IEEE) and IEEE Standards Association (IEEE-SA) published the IEEE 802.3by 25 Gigabit Ethernet standard to address growing server I/O connectivity demands above existing 10GbE. This standard defines a single-lane 25Gbs PHYs , similar to 10GbE technology, for operation over electrical backplanes, copper twin axial cables and multimode fiber. Technologies like 40GbE and 100GbE require 4 lanes (4 x 10GbE and 4 x 25GbE) to achieve their connectivity.
