Re: A good series...
We all have to start somewhere.
I've also seen floors collapse because "the guys who did our office floor, you know, the one with the carpeted tiles, did such a good job they might as well do the computer room".
I guess the point I was trying to make is that building a proper Data Centre is easy beacuse they costs a chunk of money and often are designed from scratch so even the worst PHB can see the need to have proper project management, buy proper equipment and hire proper professionals. And so, all the points from the original arcticle (all very true) are less likely to be missed (YMMV)
The real problem is at the bottom end because the cost of the "extra stuff" can be disproportionate compared with the cost of the IT you want to buy (plus it is never budgeted for). Every university has some researcher that bought a couple of blade chassis only to discover they cannot plug the bloody things anywhere.
In these cases, hosting and/or collocation can be a better solution but these are the same people who cannot bear the thought of keeping their precious servers off-site, don't have the staff to manage things remotely and cannot work out that depreciation is a real expense. And so, the poor bastard with the root password has to make lemonade.
It shouldn't be like that but that's life.
P.S. My typing skills suck.
