How Application Failover Works

Failover Monitoring

User Data or Application Data Replication

• IP ICMP or Heartbeat Monitoring

• Detect Failure in Seconds or Minutes

• Failover Server Name and IP address

• Failover DNS Records

• Start up application services

• Users can reconnect within minutes of failure

• Failover can occur across a LAN, WAN and even NAT

• Failover more than one Server Identity to the Same Target Server

• Failover Scripting for Custom Configurations

Source Target



How Failback Works

Failover Monitoring

Source Target

• Recover or Replace Source Server

• Restore Data to the Source Server

• Failback Source Identity

• Bring Source Applications Online

• Users Reconnect Within Minutes

• Start Replication and resume Failover Monitoring for Continued Protection

Site to Site Migration

Migrate workloads efficiently

between sites over any distance

Migrate from multiple sites for

datacenter consolidation




• Double-Take Portability Solutions

– Physical Virtual

• Automatically provision virtual macMigrate workloads between

any combination of physical and virtual servers: P2P, P2V, V2V,

and V2P

• hines on VMWare ESX hosts for P2V conversion or V2V

migration

• “Physicalize” virtual servers with V2P conversions

– Save Time, Save Money

• Migrate data during normal business hours and perform fast

migrations within minutes instead of hours

• Eliminate costly downtime of business critical servers during

migration or conversion

• Consolidate and virtualize quickly and efficiently

Double-Take automatically provisions

VMDKs for each workload volume

When a full workload is replicated,

migration can be completed in minutes




• Migrate Any Windows Workload– Migrate domain controllers and SBS servers

• Across any Storage– Migrate data between dissimilar SANs or iSCSI appliances or from

DAS to SAN or iSCSI

• In Real-Time– Migrate workloads with real-time replication while users are online

and productive

– Reduce downtime to minutes instead of hours

• Virtual or Physical?– Either virtualize physical workloads or physicalize virtual workloads

– Automatic provisioning of virtual machines

• Efficiency– Perform dozens of migrations simultaneously
