Seen on an email list:

Question: I need to copy over 100TB of data from one server to another via network.

Answer: What network link is there between these hosts?

Question: Network is a 10/100

Answer: You're kidding? Assuming 100baseT wire speed of about 10Mbyte/sec, moving 100TB will take a minimum of 100TB/10MB/s = 10,000,000 seconds or 2900 hours, or about 4 months. Even on a gigE network, this would still take about 2 weeks or more.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
