Subject: RE: Introduce E2K10 and remove E2K7
In Exchange 2010 it doesn't matter where you locate your HT. It can be on MB or
CAS. If you were to set up a load-balancing scenario, it is _SLIGHTLY_ easier
to configure load-balancing (when using Windows NLB) if the HT is on the MB.
The configuration is _EXACTLY_ the same if you are using non-on-board LB.
In Exchange 2010, MAPI (that is, Outlook) users connect to the CAS, not to the
MB server. Ever. If you add MB servers, they don't have to reconfigure. Ever.
(Unless you move them to a different site, but that should happen
automagically.)
If you have a DAG and one of the servers goes down - then the other one comes
up - unless it's set to not automatically activate.

Thanks Mike,
We are an ISV operating from 8 different countries of which 3 countries are
having close to 200 users.
Right now these 3 countries are operating as separate disjoint internal domains
and using their own email servers. We want to integrate all these 3 domains
into a single domain over site-to-site VPN and use a consistent email id across
the organization.
Right now we are using a...@path-solutions.commailto:a...@path-solutions.com,
a...@lb.path-solutions.commailto:a...@lb.path-solutions.com etc based on the
country code. We want to avoid this different email address.
My reasoning to split off CAS from MB, is so that even if there is any change
in MB server names due introducing new MB servers, the remote users shouldn't
be affected with reconfiguring Outlook Anywhere.
Moreover what will happen if the complete MB server with CAS HT is down even
though I have with SCR / DAG as backup repository?
The most important thing I can't comprehend is where to host the HT. Should it
be on MB or CAS?
Later we will have DR between sites. UM is not important.
Appreciate and thank you for your consistent help

Ok, then you have an Edge at each site and that brings you down to 3.
I recommend you don't collocate any roles with UM. So that's two.
Now, the question is whether you really want to split off your CAS from your
MB, and if so - why?
Secondly, what is your goal in having two separate sites? Is it HA based? Or
are you trying to cover two separate locations with no site-based HA?

Thanks Mike,
But I guess I made a mistake. Its 4 servers per site and not 4 server all
together.

First, DAG is part of the MB role. It provides HA for the MB role.
You can collocate all roles on the MB and still use DAG (this is a change from
Exchange 2007 HA roles).
If you only have four servers and you have to support two sites then your only
choice is to have an Edge server at each site and have a multi-role (HT, CA,
MB, UM) server at each site.

Oops. I am sorry.
I don't have the budget to host different roles on different servers.
The maximum I can have is 4 servers. 1 each for MB, CAS, Edge DAG.
So basically, I need 1 server with MB. 1 server to host CAS. On which server
should I have my HT? on MB server or CAS server?
I forgot to add an important point that is, I will be moving to multi site
(different geo location) domain with each site having its own MB, CAS, HT
EDGE (for only outbound mails from that site).

I don't understand this question: What all are the roles that is required on
Mailbox server and CAS server?
