EX Design for review ;) |
|
|
Hy NG
We planning to implement Exchange 2003 until the middle of the year.
I´m currently working on the design for Exchange and have a lot of ideas,
but wan´t to know if i´m on the right way or completly wrong.
Current situation:
All Servers are W2k3 Standard
2 Locations connect through a VPN (bandwidth ~ 1 to 10 MBit/s)
root-domain (company.local)
child 1 (child1.company.local) child 2
(child2.company.local)
About 40 Users in child1, and 60 Users in Child 2. The Exchange 2003
Enterprise will be located in Austria(where child1 belongs to). I also wan´t
to install the EX2003 as Member of child1. This Server will act as Backend
Furthermore we will install a EX Frontend in the perimeter network. We have
to provide all protocols Exchange offers (POP3, IMAP, MAPI, OWA, and RPC
over HTTP). This server should also work as SMTP-Gateway (AV-Scanner and
AntiSPAM)
Now my questions:
Is it a better choice to let internal users connecting through POP3 or IMAP
directly to the Backend Server or also to the Front-End in the perimeter
zone?
Is it a problem if the EX-Server is a Member of child1 or are there any
advantages if we join it to the rootdomain (which is currently just
namespace-holder)
Do you think we will expect any performance problem over the VPN if ~ 60
people check there e-mail? Should we also have a 2nd exchange located at the
other location as member of child2?
I read today "Planning an Exchange Server 2003 Messaging System" so there
where just this few questions open.
btw. another question about the RAID configuration
6HDD´s every 70GB available
my thought:
either 1xRAID1 and 1x RAID5 (with 4HDD´s) -> System and TransLogs on Raid1,
Database on RAid5
or 3x Raid1 -> System, TransLogs, DB on separated Arrays (i know that would
be the best choice regarding performance and so one, but 70GB of available
Space for the DB is maybe to less for our requirements.
or the last idea => 2x RAID 5 (System and TransLogs on one array, Database
on the second array)
I´m thankful for any tips and hints.
kind regards
Hans

Some thoughts:
Furthermore we will install a EX Frontend in the perimeter network. We have
to provide all protocols Exchange offers (POP3, IMAP, MAPI, OWA, and RPC
over HTTP). This server should also work as SMTP-Gateway (AV-Scanner and
AntiSPAM)
Probably better to host this on an ISA server vs. a FE server. Or use both,
but it's not a best practice to put FE servers in the DMZ because that would
entail putting a domain member server in the DMZ. A generally bad practice
these days. ISA is much better for what you talk about.
VPN saturation will depend on too many factors not mentioned to make a
decent suggestion. However, you should look for total saturation of the VPN
link now and possibly consider letting them use the internet if available
instead (remember that you'll providing the protocols externally anyway).
Protocol type will make a difference as will GC placement.
Disk configuration? I wouldn't feel uncomfortable with this:

My thoughts anyway.

jep, i read that too late that its "better" to use a ISA instead of a FE.
And because i'm a real ISA fan i will propose that we install it that way.

our problem is that we use a university network. of course, we have more
then enough bandwith at our side, but the colleagues in ireland have a lot
of problems. but that will remain to be seen what is possible and was not.
but all in all i thought my design need more improvment ;)
so now just the harder part => implement the whole stuff
thanks for your help
kind regards
