Price, Style, Technology? we must to star the real design and the first decision is which type?
In few words we have:
This decision will be most steer by the location, weather, where our project will take place -desert, city, offshore facility, military base,....- let say if the DC will be in a executive tower , then the traditional or Cabinets -all in one- can be the answer. But we have an open space near a city we can go trough the Traditional /Containerized. If the facility will be overseas -military, jungle or so- maybe a All in One cabinets with NEMA3 + can be the solution.
As we have our own preferences; the following issues MUST be consider by DESigner (see http://datacentresdesign.blogspot.mx/2014/03/mission-critical-facility-planning.html )
1. OPR important to deliver what the investor wants not what DESigners likes
2.1 GRC, CSR definitions
* Standards (ISO/TIA/ NMX/ EUCoC, and so on)
* Best practices (ASHRAE, NFPA, BICSI, ICC,.....)
* Classification (Uptime Institute, LEED, BREEAM, NABERS,....)
2.2 Business Continuity Management /BCP
2.3 Inside/outside customers Industry / market expected growth
2.4 IT dimensioning (#servers, storage, connectivity equipment) day ONE, 365, 720,..
2.5 technical innovation attitude
Which solution is the best? it will depend in all the above issues and resources TMT -Time/Money/Talent- of course the DESigner´s "style", age, experience, are variables that should be consider.
My point here is that OPR are the guidelines to choose type, technology, size, and so on. If we as DESigners can mantain the owners bussines needs in perspective always, then we are going to get the goal,
- to Comply law, best practices, standards, classification programs,
- to reduce Risk and
- to keep organization´s Governance
Or what do you think?
