About Gil Lalo

Enhanced system resiliency: simple yet powerful HA and disaster recovery functionality

Compliance, archiving and IRM built in Exchange 2010 can run on inexpensive SATA or JBOD disk

without sacrificing performance or availability Powerful protection against SPAM and malware User self-service features means fewer help desk calls Greater support for mobile workers – including support for all

major internet browsers Position Contoso to deploy Unified Messaging Seamless co-existence and movement between cloud and on-

premise mailboxes**once BPOS/Exchange Online is upgraded

Exchange 2010 Benefits to Contoso

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?

What type of firewall and other security is in place?

Additional Infrastructure Information Needed

What is the desired end result of this project?

?

The Big Questionto be discussed offline

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

Worksheet Sample

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
