I\"m not sure yet exactly what we\\\'re going to do.

Matt, maybe something along those lines . I\\\'ll keep my mouth.shut. LOL..

I know it\\\'s good for Cable Management which is what I like about it.

would be alot cheaper and easier to replace damaged/faulty cables with rasied flooring

in the end its not a \"must\" but a good thing to have, if you can afford it its worth while.

It actually depends on how you pipe the ac in order to chill the room. A raised for is not a must... if you link up piping and then have air blowing from both sides of the room its just as effient as a raised floor.

raised floor is from the old  days when large main frames were designed with a hole in the bottom of htem to sit on a hole in the floor to recived their cooling from the plenum space.  this is how it was done - unless of course you had a fancy water cooled mainframe like the company I used to work at had.

any way - in the hard core telco centers designed to run at 100% uptime with no hazards you will not find a shred of raised floor.                     
I would have to disagree entirely.  Any server room becomes a high candidate of becoming a fire hazard.  Just because it\\\'s built on raised flooring doesn\\\'t mean anything.  Many of the government’s top server farms are built upon raised flooring.  Government installations have the strictest rules when it comes to fire prevention and security.  Raise floors are no more a security threat than raised ceilings.  When you have a solid concrete room from ceiling to floor it doesn’t really matter.  Many of these same DCs and other commercial DCs have extremely tight security when it even comes to accessing the data floor.  In the government sector and the commercial sector, you are going to be escorting all contractors and visitors around the data floor at all times.  As to which one is better, it comes down to personal preference.  There are many factors that will determine which way companies/organizations go such as: money, ceiling height, location, and etc.  The current center I work at uses cable ladder’s above the racks.  The DC we are in the process of building will utilize raised flooring.  In one scenario you have to lift up floor tiles to work, the other you have to break out a ladder.  It all ends up becoming a personal preference of which system works best for you in your environment.  In the same matter you can\\\'t find a single reason raised floor is better, I can\\\'t really find a reason why it would be worse.

There are reasons to chose the ladder rack, or cieling based system.  First of all, it is cheaper, in almost all cases.  Second, according to most of what I have read, cooling from above, and not the raised floor type of cooling is more efficient overall.  This does make sense, as cold air falls...  In addition, in most cases, running cables above the racks is an easier and more organized process than being forced to put them underneath, forcing you to lift up tiles, go around all sorts of supports, etc.

I\\\'m not saying that you are an idiot for chosing raised flooring, if you have compared the two methods and deemed raised floors to be better for you, good.  I just see no reason for it in any setup I may have.
