How to save money in your data center operations?

What’s the biggest way to save money in your data center operations?

Required Consolidate – centralize your IT resources as much as possible for big savings and improved efficiency.

Virtualize – more virtual servers running on fewer actual servers is the key to cost-cutting.

Go for green – reduce power consumption and save on energy costs.

Reduce IT support staff – users are more capable of fending for themselves these days, so let them.

All of the above – but only in moderation. These techniques can all help, but each company needs to fine-tune its own cost-reduction solution.

BTW: I picked this up from dailytech. I was just curious to know what your choice would be.
