  29. 29. 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 can’t 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
  30. 30. 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 Darcy User Support Specialist Massachusetts Housing Financing Agency
  31. 31. Customer – “Protect Production VMs&quot; “ 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. Praneeth Machettira Online Technical Director Suffolk University Business School
