ESG Market Landscape Report on data center networking looks at data center networks. “Flat” networks are a good idea but do users really need “flat” networks? Yes and no, but most vendors have 2-tier switch clustering architectures that will be sufficient for many use cases.

I’m convinced that the combination of IEEE Data Center Bridging (DCB) and low latency switches will make storage-over-Ethernet a no brainer.”]
