The other day I was participating in a conversation with a customer about LAN and SAN speeds greater than 10G. It was a good conversation and the customer had numerous questions about migrating to 40G Ethernet; what is happening with 100G Ethernet, using multiple fibers for Fibre Channel, etc.
Toward the end of the conversation I asked them about their plans regarding deploying 40G Ethernet. They replied that they had no immediate plans for deploying 40G and that the reason they wanted to talk about it was to make sure that their LAN infrastructure could support it in the future. They plan on deploying 10G Ethernet in the new data center.
That revelation hit me with the same impact as participating in an ice bucket challenge.
