The document summarizes a presentation about Contoso Corp's planned upgrade from Exchange 2010. It includes details about the presenter Gil Lalo's background and experience. The benefits of upgrading to Exchange 2010 are then outlined, such as improved high availability, compliance features, and support for mobile users. Several questions are asked to understand Contoso's current infrastructure configuration. Specific recommendations are provided for the Exchange 2010 implementation including a database distribution plan across 8 mailbox servers in two data centers. A conceptual diagram illustrates how the new Exchange 2010 infrastructure would be set up.

Exchange 2010 Benefits to Contoso

4.  What version of MS -Office is deployed at Contoso?
 What is the OS level on PCs?
 Are the PCs centrally managed?
 Is this an opportunity to deploy Windows 7 and/or
Office 2010 globally?
 What type of connectivity exists to sites C and D?
 How is the company connected to the internet?
 How many remote users?
 How much movement between sites by users?
 Will all role servers be virtualized?
Additional Infrastructure Information
Needed

5.  What is the desired end result of this project?
?
The Big Question
to be discussed offline

6. Evaluation Process for Exchange Solution
to Determine Level of Co-existence

7. Worksheet Sample

8.  Deploy 2 DAG groups of 4 servers each across both sites
 Create 4 copies of each database and distribute across
servers
 Deploy 8 Mailbox Servers total
 Deploy 4 Hub Servers total
 Deploy 2 Edge Transport Servers in both sites configured
for failover/redundancy using multiple MX records with
equal priority
 Deploy 4 Client Access Servers in an array using Reverse
Proxy load balancing via TMG
Some Specific Recommendations
