Benefits of VirtualizationBenefits 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

www.doubletake.com

Benefits of VirtualizationBenefits of Virtualization

• Reduce the number of physical servers– Savings on hardware acquisition/maintenance– Operational savings – power, cooling, real estate– 5:1 to 20:1 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%

www.doubletake.com

Benefits of VirtualizationBenefits 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”

DR/HA for Virtual HostsDR/HA for Virtual Hosts

• Virtual hosts have a high protection need– “All Your Eggs In One Basket”– Multiple critical workloads on the same server

• Disaster Recovery for virtual machines– Real-time replication of virtual machine data– Use DR data to rebuild virtual machines

• Replicate from within the virtual machine

• Replicate from the virtual host server

• High Availability for virtual machines– Real-time replication of virtual machine data– Monitoring/Failover of the virtual host server

“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.”

“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.”

“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.”
