First off, *everybody* is different. Sun changes their mind quite a
bit over time too.
Sun's servers are among the shallowest in the bunch. Likewise, Sun's
rack cabinets are usually among the shallowest in the bunch as well.
What else are you wanting to rack-mount? How much extra space do you
want to provide for cable management?
The current x86 server depth is 29.5" rail to rail (front to back)
inside the cabinet. Accounting for power and some cable management,
about the bare minimum is thus around 36" deep cabinets, but this is
the minimum, and I also have 39" deep cabinets to allow for lots of
cable management and power options.
But it sounds like you are getting just the bare rack, so if you want
to pick up a current Dell or HP or something, you'd be looking at
having 29.5" deep rails.
The rack rails are two factors. One is that you need to get the ones
for that particular machine. They are all different. Two is to make
sure they are adjustable to fit your rack. The best option for
everything is to make sure your rails are adjustable somewhat. Most of
the current crop of x86 boxes are adjustable by an inch to an inch and
a half. Some of the older HP rails are the most flexible, not sure
what they are currently shipping, everybody's bringing in Dells now.
I've seen some of the cheaper 4-post rail only racks not even offering
setting the depth at 29.5", just 29" or 30", so having some of the
flexibility is a definate plus oftentimes. The Dells still work in
those, but something that is fixed depth often won't.
There's been alot of changes and whatnot in this area (ie. just go
back 6 years, and see what people were doing then. Pretty much 100%
change around, and servers have gone from 15-18" out to 28" deep), so
there's lots of things out there that might work, but current x86
servers are targeting that 29.5" rail depth...
