[gpfsug-discuss] Connecting IBM ESS 3200 to 10 Gb Ethernet

[Alec]

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.
