data center and TIA-942 standards


We have a DC that does not meet the latest standards at all. It is managed by an individual that is "set in their ways" and doesn't take change too well. I was tasked with cleaning up the DC and make it functional again. I'm at the point where I need to do some serious cabinets, cables management, server/rack allocation management, network management, etc

This guy won't budge....his only argument is that an enclosed cabinet (which is recommended) will reduce airflow by 50% because of the meshed doors. I explained to him that this is something that has been addressed and handled in the new standards but he doesn't believe it. He wants me to, literally, prove to him that a new enclosed cabinet will provide the same cooling as is current open-concept cabinet (no walls or nothing to manage cables)

The funny thing is, we have another DC that is for our prod network and it's all been retrofitted with new cabinets, etc and meets the latest 942 standards...but he still won't budge....

what can I do to convince him? How can I prove to him that the new standards work? Are there white papers/docs that discuss this?

Any help will be appreciated!

I think the logic is flawed from the start, so you can't argue against it.

With standards, you don't need to provide "the same".  You need to meet or exceed the new/current standards.

I could get better cooling by refrigerating the room to 64F with massive air movement.  But is it necessary?  I keep my room at 76F ambient with a primary and supplementary HVAC supply.  Much easier on the electrical supply costs than the last room, which was set to 68F 24/7.

I could also turn out all the lights to shed heat load.  But, then we invented fluorescent tubes, timers, motion sensors, etc.  We also got more stringent emergency lighting standards that prohibit dim caves.

Keep in mind that ASHRAE's been developing standards for data center cooling.  TIA-492, since it deals with more things in general, may lack the specificity for any one system, and definitely lacks specificity for one location.  I've seen criticism that's it's a 'cookie-cutter' approach, not a project plan with site-specific details.

His argument has merit from his standpoint.  Using the standard as a checklist does not necessarily mean your data center is better.  It means the contractor(s) get a more standardized punch list.  It also limits what is deemed "necessary" for operations, which could decrease costs or increase additional revenue for items outside the new standardized scope of work.
