GEO assures seamless failover and failback to the best performing and geographically closest datacenter for optimal use of web-based applications, including Microsoft Exchange. In the event of a service disruption, traffic is automatically controlled based on a set policy in order to minimize impact and the need for manual intervention.

The GEO product is available in two forms:

  • A standalone GEO product
  • A Global Sever Load Balancing (GSLB) Feature Pack that is part of the LoadMaster product

GEO offers many load balancing algorithms including round robin, weighted round robin, fixed weighting, real server load, location based and proximity. “Round Robin” load balancing can be used for all active data centers, which includes support for weights and a chained failover option for disaster recovery. Location Based load balancing allows GEO to direct a client to a data center based on the client's country or continent, as defined by the created policies. Proximity takes Location Based one step further and allows for longitude and latitude granularity for definition of proximity. GEO securely and seamlessly integrates with LoadMaster to offer “Real Server Load” load balancing, in which GEO uses local data center metrics provided by LoadMaster, allowing clients to connect to the least busy data center.

GEO can be deployed in a distributed (Active/Active) high availability configuration, with multiple appliances securely synchronizing information. Introducing GEO in your existing Authoritative Domain Name Services (DNS) requires minimal integration work and risk, allowing you to fully leverage your existing DNS investment.
