As enterprise digital transformation gains momentum, data has become a key production factor. In turn, data centers — responsible for data computing, storage, and forwarding — have now become the single most important piece of critical digital infrastructure. As a result, data center Information Technology (IT) architecture, computing units, and storage media are all undergoing a seismic shift, driving Data Center Networks (DCNs) as a whole to evolve from multi-protocol to all-Ethernet.
