Hi,

We have a data centre here in our building.   I'm looking for some good
information on how to install/maintain the structured wiring for the DC.
Can anyone provide any good whitepapers or links to tips?


Thanks,



Dave

APC has lots of great info on data centers. Here is their page that you
want to check out:

http://www.apc.com/tools/mytools/index.cfm?action=wp

It is, obviously, heavy on UPSes and all things power due to their
specialty in that, but you'll find lots of useful info on racks, cabling,
cost of ownership etc. Good place to start.
Good luck!

    Label, label, label!  Document, document document!   Stay neat and
tidy.  Hire me to do it. *grins*

I worked briefly for a company, where the boss had an aversion to
documentation.  He actually discouraged us from documenting our work.

I don't have any really good suggestions but I'd get the FlexTray
catalog for pictures and possibly product and maybe conteact them for
info.

http://www.flextray.com /

Also contact the manufacturers of CATx parts and ask if they have any
planning info.  

If you have a major vendor (HP, IBM) providing the big systems
they have planning documents that will give you clues about
the infrastructure they expect.  

IMO people don't pay enough attention to power distribution
when they are doing their first installation.

Don't blame me. I voted for Gore.


Re: Data Centre Cabling


  How cabling is routed avoids what should be trivial
problems, as demonstrated in an IEEE paper from Montandon and
Rubinstein in the IEEE Transactionson on Electromagnetic
Compatibility  of 4 Nov 1998 entitled "Some Observations on
the Protection of Buildings Against the Induced Effects of
Lightning".   They summarize:
> 1) ... a single entry point should be used for all incoming
> services in order to avoid that part of the lightning current
> flows through the building ...  fig 9
> 2) ... large loops should be avoided by sutiable cabling
> routing inside the building (see fig 10). ...
> 3) Do not establish equipotentialization by multiple bonding
> of sensitive power or data cables to different potential
> reference points within a structure.  ...
> 4) Follow within the building a boding and routing concept to
> interconnect different equipment by power and data cables
> according to the principles shown in figure 12.

  Demonstrated by Montandon and Rubenstein is also done for
other reasons. Nothing above is comprehended without either
those figures or previous knowledge of the principles.

  Sun Microsystems also demonstrates principles in "Planning
guide for Sun Server room".  For example, this routinely
understood principle for cabling should be known to anyone
setting up a data center:

> Lightning surges cannot be stopped, but they can be diverted.

  Provided are the 'of course' examples that any serious data
center planner knows.  If this information is new, then so
much more is to learn.  Many data centers suffer interruptions
and foolishly assume it was not due to human failure.  Even
how cables are routed can adversely effect data center
reliability.   Adverse effects from lightning exampled here
only because too many data center planner don't even
understand the above 1930s electrical technology.
