KB, Kb, MB, Mb, GB, Gb what's what

You mention in an earlier response that Fibre Channel is now 100MB per second and going to 1G and later 2G. Isn't 100MB per/second the same as 1G bits/second? And when the 2gbit stuff comes along it will really be 200MBytes per/second?

The current Fibre Channel standard is 1Gbit per second, (100MByte per second). The next generation will be 2Gbit per second (200MByte per second). Future speeds will go to 10Gbit per second (1GByte per second). I hope this makes it clearer. You are correct in that 2Gbit will really be 200MBytes.

Some terminology refresher:

Kb=kilobits
KB=kilobytes
Mb=megabits
MB=megabytes
Gb=gigabits
GB=gigabytes
