Benefits of Virtualization

• Compelling Value to IT
• Server Consolidation
• Reduced hardware costs
• Server Rationalization
• Efficient use of resources
• Operational Flexibility
• Rapid provisioning and allocation
• Easier and Less Costly DR

Virtualization Enables Reduced Costs and
Complexity
10
Benefits of Virtualization

• Reduce the number of physical servers
• Savings on hardware acquisition/maintenance
• Operational savings power, cooling, real estate
• 51 to 201 consolidation ratios
• Improve resource utilization
• Utilization of standalone servers 10-20
• Increase capacity without more hardware

Typical ROI is 6-12 Months Reduce TCO by up to 60
11
Benefits of Virtualization

• Streamline and standardize deployments
• Server provisioning goes from weeks to days
• Virtual machines share common/standardized
  configurations
• Reduce DR costs without sacrificing capabilities
• Less hardware required at DR site
• Simplified operations at DR site
• Virtual machines are hardware agnostic
• Virtual machines are portable

Customer - Virtualized Target for DR
We have 25 Windows servers including 5 SQL
servers in production in San Francisco,
replicating with Double-Take to a VMware server
in New York. I cant imagine how we could have
implemented anything else as effective for
disaster recovery. Double-Take and VMware are
true solution providers, not just software
companies. Our executives demanded the best in
disaster protection for our organization. This
combination was it. Kenny Tam Network
Manager Shorenstein Realty Services, LP

Customer - Virtualized Target for DR
Currently, we have nine production servers
replicating data to four ESX hosted virtual
servers for disaster recovery purposes. Utilizing
Double-Take in conjunction with VMware enabled us
to consolidate our disaster recovery environment
and ensure a cost-effective approach to
protecting our systems and data. Thad

Customer Protect Production VMs"
The performance of Double-Take has enabled us to
go about business as usual so that system outages
if they occur are essentially transparent to
the students and faculty who use our online
platform. If a primary server goes down in
Boston, we now have the capability to minimize
the disruption to seconds. Double-Take provides a
much needed buffer for our small IT staff. Dr.
