What is Data Center Interconnect?

According to data insight provider GlobalData, the global cloud ecosystem is expected to grow at a Compound Annual Growth Rate (CAGR) of 25.3%, reaching US$720 billion in 2022. Critical to such growth, Data Center Interconnect (DCI) serves as the key infrastructure connecting data centers. But what exactly is DCI?
In very simple terms, DCI refers to the technology that links two or more data centers, allowing them to communicate with each other, sharing data along with compute and storage resources, as well as providing backup, redundancy — and more. This can span relatively short distances, from one side of a city to another, for example. Equally, it can cross continents, traversing oceans through subsea cables along the way.
And while speed, bandwidth, and capacity here obviously count, DCI solutions are actually about far more than just that. Additional features — such as simplified Operations and Maintenance (O&M), intelligence, and security — are now also necessities, not just extras, in an increasingly digital world. And it's features just like this that are integral to Huawei DCI solutions, helping them stand out.
