This many standards is dumb: Decoding 25Gb Ethernet and beyond

Sysadmin Blog The 25 and 50Gb switching standards have finally been ratified. Switches from various manufacturers have been available for some time, but now there's a better than average chance they'll interoperate with one another. While more speed is generally good, the 25 and 50Gb standards will complicate things for data centre …
