None in between. I prefer 4ft front and back, but I'm pretty sure that
exceeds the regulatory minimums. I like to have a little room when
operating on equipment.

RE: Placement and spacing of server racks

2011-09-02 Thread Maglinger, Paul 
Side to side isn't that important.  Side to wall is, in that you need to
make sure you can open your rack doors wide and also give yourself room
for two people to mount equipment (one on each side).  Make sure you
have room in front and back of the racks that you can easily install and
remove your equipment.  Try to have adequate lighting in front and
behind so you can see what you're doing.

Subject: Placement and spacing of server racks

 

Greetings! 

Our server room is finally getting some badly needed upgrades (including
the removal of a partial wall, more power, and a real server room
cooling unit). 

We currently have three server racks.  Once this renovation project is
complete, we will be adding two fairly full server racks.  We are hoping
to have these upgrades keep the room adequate for another 5 years.  So,
depending on the recommendations of rack spacing, it may be necessary to
take out another wall and expand into what is currently an office. 

So, the questions are: 

1. How closely together do you space your server racks?  That is, how
much space between each rack? 

2. How far out from the walls to you have them (both for air flow and
for rear access)? 

I believe the current dimensions of the room would allow 7 racks (and we
are already claiming space for 5) along one wall and with room for
another 1-2 on another wall.  Your recommendations may force us to
re-consider. 

Thank you...

We have six racks of equipment. no spaces between the racks. It will mess up
your airflow

2. How far out from the walls to you have them (both for air flow and for

RE: Placement and spacing of server racks

2011-09-02 Thread Charlie Kaiser 
My placement is simple assuming that environmental (power/HVAC) and network
cabling is adequate; I make sure I can open the rack doors completely if
installed, I make sure I can slide the servers all the way out for
maintenance (don't want to have to move a rack to install a server), and I
make sure I don't block doors/vents. Side to side I butt them right up
against each other. Unless you have a specific need to get into the rack
from the side, I've never found it to be necessary to spread them out that
way...

1) None.
2) Check OSHA and any local building or safety regulations.  Those will
drive the minimum distance.  That minimum will exceed what you need for air
flow.  Keep in mind those regulations will usually apply from a door open
perspective. (start the measurement from an open door, not closed)
