I've used a colocation service for about 3 months. This is my first touch to run web servers in a data center, so I don't have any idea and information about server hosting (or colocation).
Now, I'm running 15 1U servers in a full-rack because the data center has a payment policy depends on electricity usage. So there're a lot of empty slots in my rack, but I paid also space fee for the full-rack every month.
Is this case is common? I cannot use rest of space in the rack because of their 'common' hosting policy. They said that it's common and general rule in US, are they right? Please tell me the truth if you know anything about it. Thanks!
