Case Projects

Case Project 7
-
1: Choosing an Administrative Groups Model


Because you

are transitioning from Exchange Server 5.5 to Exchange Server 2003, your
administrative and routing group model will mirror the site model within Exchange
Server 5.5. After you have finished the transition from Exchange Server 5.5 to Exchange
Server 2003,

you have the opportunity of restructuring the model to better fit your
organization’s administrative requirements.


Case Project 7
-
2: Designing Routing Groups


As part of your migration from Exchange Server 5.5, you have considered your
administrative mod
el and now want to consider the routing model for your organization.
What are some of the issues you should consider when designing the Routing Group
Model for your organization?

When considering a Routing Group model for a new organization, some of the fa
ctors
you should take into consideration include:




The availability of connectivity between servers



Whether all servers will be part of a common Active Directory forest



The bandwidth between servers

The most important factor to consider when planning your

routing group boundaries is
the stability of the network connection, not the overall bandwidth of the connection. If a
connection is prone to failure or is often so saturated that the effect is a loss of
connectivity, you should place the servers that the

connection serves in separate routing
groups.


Case Project 7
-
3: Designing Front
-
end/Back
-
end Server Implementations


Because you are implementing a Web e
-
mail infrastructure for distinct organizations that
you will host, the most advantageous model is to

implement separate HTTP virtual
servers and a front
-
end/back
-
end server configuration. This allows mailboxes to be
moved on the back end without requiring the infrastructure to be modified to
accommodate this load balancing. In addition, each company can
be represented as a
distinct organization via separate SMTP domains even though they are implemented on
the same infrastructure. This allows them to reference the e
-
mail infrastructure using a
single SMTP namespace instead of referencing it using a name th
at is common to all the
hosted organizations. This, in turn, masks the physical infrastructure, providing additional
security by not revealing the physical topology.


Case Project 7
-
4: Managing HTTP Virtual Servers


Because the organization is experiencing

heavy load, it is possible to alleviate some of
this load by reducing the connection timeout value from 15 minutes to something lower.
This terminates persistent connections sooner and allows connections by other servers
that are trying to communicate wit
h the server. This, in turn, increases the throughput, as
more connections are achieved in a shorter period of time.
