Switch attach rate on servers
"Tried and true Gigabit Ethernet is still going strong in enterprise switches, but they will shift to 10G in the next two years, probably by vendors pushing their strategies," Weckel said.
10G will get one last burst of growth from enterprises transitioning to 10GBase-T, the copper version. Cloud datacenters are deploying 10G today and looking at higher speeds such as 40G and 100G, he added.
Unfortunately for vendors, margins are shrinking. "40 Gbit has no major price premium. Price premiums are shrinking -- that's going to change how people architect and build their networks."
