software differences b/w 2k server/adv_server

I know the hardware support diff. b/w win 2k adv server and win 2k server, but what are the other differences? IE what software comes with adv server that doesn't come with server, and what functionality does server not contain that adv server does? i searched around for this and could only find hardware differences for the two. Thanks.
 
The only software difference I can think of is clustering, you can run cluster server on adv server but not regular server.
 
I recently read an article somewhere on aceshardware.com (I think it was actually a CPU article) that detailed some of the differences.

I think Win2K server is limited to using 4 gigs of RAM and can only allocate a max of 2 gigs per process (the same as 2K pro), whereas Advanced Server can access 16 gigs of RAM and allocate 3 gigs per process.

Xeon processors have extensions called PAE or something like that that allows the 32 bit x86 CPU to address more than 4 gigs of RAM by copying data between memory above 4 gigs and a "memory window" below the 4 gig border. The performance isn't that great on it (and that's why some high performance tasks are on MIPS, Sparc, and 64 bit platforms.

Also, I think Server only supports like 2 or 4 CPUs whereas Advanced server will support up to 8 (or maybe 32 ... not that anyone has made a 32 way x86 system)

I provide a little support for some servers and advanced servers at work. I know Advanced server is also required for clustering, but I have seen little software difference beyond that.

I believe the /3G switch (to split the 32-bit 4G limit per process 3/1 instead of 2/2 is available in Server, but not totally sure. If you have a process that needs that much memory you're much better off running on a 64-bit system anyway.

The PAE limit is 64G and it's similar to the old 16-bit segmented access, i.e. real ugly and clunky. Even 1G and up can get ugly because no ISA cards and some PCI cards can DMA to there making tight memory situations hard to cope with.

Pro supports 2, Server 4, Adv Server 8 and Data Center server up to 32 IIRC. There are 32 way x86 systems, they're just not used often because 99.99% of the time it's more cost effective, and reliable, to cluster 8 quad boxes instead.
 
hm. if you read his original post, he said he already knew the hardware differences... and wanted to know purely the software.

btw, what need do you have of server or advanced server anyways? just out of curiosity...

yes, i knew alread about the hardware.

my need for server/adv server is the client licenses included and domain controller/active directory/dhcp capabilities. later
