Dealing with Data Center Interconnectivity Challenges

We are all aware of the ever increasing significance of the data centers and their proliferation across the world. Their physical position is also vital to the data center operators for addressing aspects such as minimizing exposure to natural calamities, reducing consumption of power, and their end use proximity. With the constantly increasing number of organizations linking their corporate networks to multiple cloud providers, the interconnection between the data centers of customers and providers is critical, thus increasing the demand for flawless reliability, flexibility, and seamless capacity.

However, there are many Data Center Interconnect (DCI) challenges that need to be addressed by operators to be successful. Here’s a look at the five major challenges organizations encounter while trying to achieve efficient DCI.  


The application data sets that enter or leave the data center are generally large these days because of the quick progress of video-oriented content – they can even be hundreds of terabits or gigabits. This, in turn, calls for a very reliable and high capacity network connection between the data centers so that the vast growth needs in data center traffic can be scaled accordingly.

Distance Limitation

A connection that comes with minimal latency is vital for data centers so that time-sensitive applications can operate properly and there’s proper synchronization between the server that sends the info and the device that stores it. But when the data centers that are to be linked are physically far from each other, there’s an increase in latency.

Selecting the shortest physical path can reduce the latency induced by fiber, though the networking device should reduce the latency induced by hardware to a minimum through proper designing. The advancements in optical transmission technologies, smart latency-oriented traffic routing intelligence, and Digital Signal Processing have permitted networking providers to launch platforms with the ability to ensure minimal latency without any kind of compromise on performance or speed.

Security Exposure

Generally, the information that gets stored in data centers is confidential and critical for businesses, thus emphasizing the need for secure and reliable network connections. This often needs network encryption.

Stringent rules and encryption are extensively deployed for safety against intrusions, while the advancements in networking devices can also provide in-flight encryption of data for increased security. Encrypting the network transport layers ensure encryption without modifying the content or reducing the traffic throughput.

Time-Consuming Manual Network Operations

Manual network operations are complex, error-prone, slow, and labor-intensive, so automation of recurring and frequent tasks is vital. Managing the connection between data centers should be void of any manual operational works.  

Optical networking platforms are purposely developed carefully for DCI applications and this helps faster interconnection between data centers. Full programmability permits operators of data centers to develop applications for specific requirements. There are rich management options that permit the network operators to reactively and proactively keep up the health the interconnecting data centers.

Growing Costs

With the anticipated growth of traffic between data centers nearing 30% CAGR, the costs of networks must rise at a slower rate so as to ensure the financial viability of data center in the future.

If data centers should stay financially workable, costs shouldn’t increase linearly with ​the growth of bandwidth; rather, the industry is advancing through high-speed networking at the lowest possible cost for a single bit. Solutions that reduce consumption of power and occupy less space will bring down the operational costs.

With the right networking technologies and equipment, data center operators can enhance DCI and manage interconnectivity in a better way.
