How to Use PowerLink and DNS for Redundancy and Failover

Organizations with critical applications are exploring the benefits of disaster recovery sites for their datacenters to ensure business continuity. Special network technology is needed to ensure site failover and fallback occurs reliably and predictably.

Download this white paper to discover how companies requiring WAN link redundancy, site redundancy and disaster recovery for their datacenters can use PowerLink for an integrated, affordable alternative to BGP routing and global load balancing.

Discover how to achieve Internet connectivity, site redundancy and failover using PowerLink as the DNS authoritative server to:

• Enable WAN link redundancy, ISP failover and Internet high-availability with multiple links for critical application delivery
• Ensure users get the best network experience possible over the WAN
• Guarantee traffic will be directed only to “available” WAN links and sites
• Manage inbound and outbound traffic over multiple WAN links
• Provide failover to a secondary datacenter if all links at the primary datacenter are down
• Remove deployment barriers and the high cost of multi-homing with BGP
