The exclamation point was used to denote incredulity and frustration,
not excitement. ;)
99% of 10 GbE deployment is switch stack interconnection, i.e.
backbones. It's used very little in HPC environments--Infiniband
dominates there. Very few servers today have 10 GbE connections. When
they do they're used for dedicated iSCSI SAN traffic, not user traffic.
Statistically zero desktops/workstations today are using 10 GbE
connections. If they do it's for a specialized dedicated application
such as satellite data stream processing, etc.
In short, you likely won't be seeing 10 GbE outside the datacenter or
internet POP/hotel any time soon. 10 GbE can transfer 1.25 GB/s in both
directions. That's one quarter of a single layer DVD per second in each
direction, 4 seconds to transfer the whole DVD. Very very few
individual servers are capable of such sustained throughput. Thus, 10
GbE is used almost exclusively as an aggregation pipe, or backbone.
