There will always be plenty to talk about on the technology end of things, since things are constantly changing. For example in the not to distant future those data centers that pulled out the old chilled water systems used on the mainframes will have to reinstall it. Due to the increasing heat load from high density systems, chilled water cooling is coming back. I already received info from IBM and HP that in the not too distant future servers will be going back to water cooling. Just look at how storage has changed, SAN and NAS is really taking off now that the pricing has come down to more affordable levels.
