BTW, I'm not the same Chris that started this thread. Just wanted to chime in about the 4GB/32-bit thing. Thanks for the info. I'll be reading those articles as I can throughout the day.

See TechNet articles 268363, 283037, 255600 and 170756 and I think all will become clear. As I understand the applications don't even know of the extra memory and don't need to. I must admit this is something I only recently found out about. I have to confess that I really don't see why you need so much memory especially considering it is DDR 1600. I really do believe the money would be better spent elsewhere. the machine spec. I attached was for the exact same machine you are considering. Hope that helps and don't hesiate to get back to me if I can help further at all.

In the 32-bit computing world 4GB of memory is a hard limit. 32-bit processors and 32-bit applications are incapable of addressing more memory than that (2^32 = 4GB). I also believe in the Intel MP arena the processors share the memory bus so even MP boxes can't use more than 4GB. The machines you're listing are likely non-Intel chipsets or specialized high-end MP chipsets, and if so they're above my knowledge horizon and could very well handle more than 4GB. But I think the 4GB limit for any single 32-bit application still holds true (which should even include all 32-bit versions of Windows Server). I'm not familiar with Advanced Server's ability to address more than 4GB of RAM. This is something I'd very much like to learn about.

Windows 2000 Advanced Server does up to 4GB out of the box or with /pae in the boot.ini 8GB. I hope you don't mind me saying but if I were you I would go with 2GB and get 3Ghz processors instead. Also make sure you use 15K drives. I believe you will get much better performance than simply supplying more memory. I am confused why you are giving so little disk space to the Store since the smallest drives Dell do for that server are 36GB? I asume you will be running a R1 + R5 + HS disk combination? Remember that in practice the Store should never consume more than half of the available space at the most to allow for maintenance operations. In fact why do you need Advanced server and with so little disk space in your suggested combination why use E2K Advanced at all? Windows 2000 Standard supports 4GB of RAM and Exchange 2000 Standard supports a database size of up to 16GB. Are you planning on multiple stores. Is the extra cost for Exchange Advanced server for that worth it for only 50 users. Below is a basic spec of the sort of machine I hope to purchase soon as I am considering the same machine with similar user base.size.
