Many network storage engineers simply don't understand bandwidth (or the importance of port groups)... With an ESS you are talking GIGA*BYTES* per second and storage and networking architects simply see 10Gbe and assume that's good enough. A 10Gbe connection can do about 1.4GB/s.. 100Gbe can do 12.5GB/s. To the wrong engineer you can explain this until you're blue in the face and they won't get it. You need to divide Gbe by 8 to get about the GB/s throughput. Explain to them that a USB-C interface is capable of 10Gbe... So you're throttling millions of dollars in technology to the speed of a consumer grade USB-C interface. When infact an ESS can drive at least 2x100Gbe to saturation.
I don't have an ESS but a classic SAN array and Spectrum Scale and I can saturate 32*8Gbe fiber connections.
