SMTP on cluster (and more) |
|
|
Hi all.
Is there any reason that a smtp virtual server can't be run on a back end
cluster? Seems that the more I read here, the more I find that won't work
in a clustered environment.
I am migrating from 5.5 to a front-end, clustered back-end topology. I now
see that the SRS will not run on a cluster or on a front end server. I am
planning on having a temporary box be the SRS until Exchange 2003 is in
native mode. Is this a good plan?
Thanks for all the great information.

That is how they programmed it. Best Practice is to separate it to the front
end. I like the temp box for SRS, that would also make a good front end
server :)

Rod,
What is the advantage of having the smtp virtual server on the front end
box? My thinking in putting it on the back end was that it was one less
point of failure (since back end is clustered). With my original plan, if
the front end box fails, I can still send mail.
On the other part of your response, were you recommending 2 front end
servers? My plan was active/passive clustered back end, single front end,
temporary, SRS box, single owa/isa box in the dmz. Flawed??
Thanks,
Aaron

Think holes in the firewall. Either on the front end or an appliance in the
DMZ. This is just my guess as to why they (Microsoft) block it.
Only 1 FE, after the fact. Two during the migration.

Re: SMTP on cluster (and more) |

I forgot one thing on my list. I have 2 webshield e1000's in the dmz doing
smtp relay. That's why I didn't think of security for the back end cluster
housing smtp virtual server.
Just so I am clear, MS wants SMTP on the front end, and not the back end,
but they don't support clustering for front end servers? If this is the
case, waht are people doing for fault tolerance on the front end?
Thank you very much. Without the information from this forum, I would be
hosed!

You can do NLB with the front end servers, works great and is fully
supported.

Re: SMTP on cluster (and more) |
|
|
My environment is as follows
I have 2 sites , Site A and Site B .
Site A has a) Exchange 5.5 Mailbox server running IMS that directs incoming
/ outgoing internet mail to mail relay server in DMZ.
b) 1st Exchange 2003 non clustered Bridgehead server that would be
configured with RGC for mail flow between Exchange 5.5 in Site B and
Clustered Exchange in Site A once Exchange 5.5 in Site A is brought down as
well as RCA will be configured on ADC Server between Exchange 5.5 in Site B
and Exchange 2003 AD
c) 2 node Active Passive Clustered Exchange 2003 Server
Site B has Exchange 5.5 server.
My question is
Can I configure SMTP connector on Clustered Exchange 2003 Server in Site A
that will direct incoming/outgoing internet mail to mail relay server in DMZ
instead of the current Exchange 5.5 Server in Site A
OR
Should I be configuring the SMTP connector on the Exchange 2003 Bridgehead
server in Site A?
Thanks in advance,
Manoj
