I think the bigger problem is that you normally need hardware to last a
large number of years.  Most organisations try and keep there hardware till
it dies.  Although we only use 32 bit OS's at present we already spec our
Citrix servers with 8GB and Dual core Procs.  If we didn't do this now we
would never get the money latter to upgrade.  The thought process here is
that when you go to 64 bit in a year or 2 when it has much more support in
theory your hardware will cope without upgrades.  Looking back at some of
our older servers it sometimes cost more to upgrade memory (you have to
discard all of it and buy all new ram) than what it does to buy a new
complete server.  
 
We currently use 2000 Enterprise with PAE and in extreme cases the /3GB
switch because of horrible apps already.

Hi Michael,
 
If you look at the Microsoft documentation, you'll find the maximum amount
of physical memory you can use on the 32-bit 2003 standard edition is 4 GB.
While using enterprise edition and PAE etc let's you lift that limit, a
well-specced terminal server system is likely to be limited by kernel memory
constraints.
 
Unless you're running the X64 version of PS4 and Windows server 2003, or
using those machines to run VMWare ESX and multiple Citrix servers as VMs,
you've just watsed a large amount of money on hardware that isn't going to
be used.
 
regards,
 
Rick

We have several new servers that we are adding.  They are Windows 2003 and
Citrix XP.  We have loaded them out with 16gig of Ram.  I have seen forum
messages about servers not using that much RAM or applications not using it
etc. and was wondering if anyone knows of any legit articles covering this.
I have noticed on these boxes that about 3 gig is actually being used and
our paging files are being used up to 50 to 70%.  I am trying to determine
if it is actually buying us anything by putting that much ram.  Or if there
is something else we need to do to get the systems to use the Ram.  
 
If you know of any articles or information I would much appreciate it.


Thanks,
Michael Boggan
