Read/understand
sizing, scalability,
capacity guidance
• Documentation on
technet, Exchange
team blog, etc.
Collect data on
existing deployment
• User profile
(messages
sent+received per
day)
• Average message
size
Define constraints
based on customer
requirements
• # of copies
• Backup
requirements
• Storage architecture
• SafetyNet duration
• Virtualization
• Growth plans
• 3rd party products
Input profile data and
design constraints into
calculator tool (or
calculate manually)
• Always use the latest
calculator
Consider impact of
various options
provided by sizing
results
• Cost
• Rebuild times
• Impact on high
availability
Finalize design
• Storage calculator
provides
configuration scripts
• Archive the
calculator as
documentation of
the sizing process
