Good comments.

I have seen recently where a couple of areas
and organizations had everything on one box.
Usually, if email went down then the printers
and authentication still worked, etc. etc. etc.

Good planning ahead makes life easyyyyyyyyy

Howdy,
I agree with your consultant regarding putting the backup on a different
box.

After years working with ArcServe, Backup Exec, Retrospect, and other data
backup software and assorted internal and external tape systems, have come
to the conclusion that backup software and hardware is touchy. Putting the
backup system on a seperate box will enable you to do reboots and tweaks as
necessary, with no visible downtime to your users. 

Good luck.

Mark,

I have just gone through the exact items you have mentioned below.

First, I personally would never, ever put Exchange on a Domain Controller.
These are two different/separate functions and if one goes down, you could
take everything else down with it.

Our AD DC's authenticate, run DHCP an DNS and perform the AD/Global Catalog
functions.

Our Exchange Server is actually the big power-horse running and moving email
constantly all day. I never wanted to integrate or mix the two.

We are backing up Exchange with an actual tape drive built into the Exchange
Server hardware. These mailboxes are critical, so I want a local tape drive
for
backup.

Now, before I have backed up across the wire with no issues, so the call is
yours.
We have tape backups for the other servers and the one attached to the
Exchange
Server is ONLY for Exchange backups.

We, also configure a 'mirror' for the operating system with 2 large drives
and the
'data' drive is Raid 5. Good planning on your end.

Let me know if this helped at all.

Richard

Hello,

   I am currently building and Exchange 2000 server and Windows 2000 Active
Directory network.  We have on site an external consultant, and his
recommendations are that we make our Exchange server box as a Domain
Controller. His reasoning for this is that the Microsoft connector to Active
directory is not good, and with the power of computers in today's world, the
additional load should not be a problem.

   In addition, he recommends Disk mirroring for the system partition (drive
"C"), and RAID 5 for the data (Drive "D"). I was under the impression that
this would be a good idea if you have two controller cards, unnecessary with
one controller.

   Our server specs are as follows:

Dell PowerEdge 2500 933 with 1 Gig RAM
6 x 18 gig hot swappable removable hard drives
2 drives for mirroring
4 for data RAID 5

   Our consultant also recommends placing the backup on a separate machine
(not the exchange server) and backing up the store through the wire. Our
information store is currently 15 gigabytes. I think it would be better to
have the backup on the Exchange server.

Anyone have any comments or thoughts on the above three items?

Please let me know.

Regards,

Mark
