win2003, Exchange2003, NUMA & 4 gig mem limit

[jose]

Hi everyone,

Is there any way to use more than 4 gigs of ram when using win/exchange 2003 32-bit ? Can't switch to 64bit os.

What about using Dual Opteron mobo's w/ NUMA support ?


Thanks for the help.

Regards,
Jose

I believe Exchange is both /3GB and /PAE aware so yes.

Search on PAE. (oh, and *never* use both of those switches together. Pick one)


Edit: Here ya go.. http://www.microsoft.com/whdc/system/platform/server/PAE/pae_os.mspx

I found some info stating that 2k3 enterprise supports 8gigs and datacenter supports 32gigs of ram..

Anyone have any server benchmarks comparing Xeon to Opterons ?

Exchange 2003 is not PAE aware, so it can't use more than 4GB of RAM.

Here's a good article about the use of /3GB with Exchange 2003 and Server 2003: http://support.microsoft.com/kb/823440/en-us

Wow, so you can buy new hardware but not a 64-bit OS. That's kind of wierd.

oh and your best solution:

4 64bit Quad-core CPU's + 64bit server 2003 R2 (+ any SP's) + 64bit Exchange 2007 + 16 (or more) GB RAM.

Done deal.

MS says you have to have 8 servers to run all the stuff they're runnnig on 2 right now(2 diff. locations).

Add all the CAL's and that up's the cost .. 100+ user's x CAL's for each server = not enough vasaline to make it bearable ... haha..
