There would be a little more to gain than that but often that's the

I can honestly say I'd agree with him on this one. Software mirroring
for this type of application is never a good idea. The slower spindle
speeds likely won't be enough of an issue to matter in your
configuration. Unless you have a very large DIT <queue jokes here> or
applications that pound the snot out of the individual servers spindle
speed won't be nearly as important. Since it's 64 bit you're after,
spend some money on the memory and take advantage of the cache as much
as you can.

What would the partitions on the first configuration gain you (over

The mirrors would be in hardware. Software raid - only time I've ever
lost customer data was due to software raid. Never again.
Splitting a large volume into two partitions gains nothing IMO.
Personally I like my databases on different spindles than the OS.
We have some Unix based apps that hit the DC's pretty hard. Their use is
only going up. We should be able to fit the DIT in memory so I think
I'll push for that. Not sure it's a battle I can win but it's always fun
to try.

Subject: [ActiveDir] DC Configuration
We have some budget money to replace domain controllers this year. Not
all of them but probably half of them. We've pretty much decided on 64
bit Dell PowerEdge servers. Most of the discussion is about disk
configuration. Two schools of thought exist here.
1) 2x73GB 15K drives in RAID1. Carve up the volume at the OS level with
20GB or so for the OS and the remainder for NTDS, Sysvol, and system
state backups
2) Two sets of 2x73 10K drives in RAID1. The first set is for the OS,
the second is for NTDS, Sysvol, and system state backups.
I've always liked physically separating the OS from the application
data. Others here like carving up the volume at the OS.
Any thoughts, opinions, suggestions?
tia, al
