ZXTM LB is available as software, as a hardware appliance and as a Virtual Appliance (for VMware Virtual Infrastructure 3 and Windows Server 2005 R2).
ZXTM LB allows you to create a fully fault-tolerant cluster of server machines by protecting against failures of back-end server nodes and front-end load balancer units. Providing that sufficient balancer and server machines are functioning, the cluster will continue to operate without failure.
If a server goes down, you need to know that your web sites will keep running. ZXTM LB can seamlessly handle server failure, redirecting traffic to a different, healthy machine without your customer ever knowing. What's more, because ZXTM LB can be deployed in fault-tolerant pairs, if a balancer machine is unavailable, another machine will automatically handle the traffic until the problem is fixed.
ZXTM LB is a future-proof and scalable solution that can be adapted to meet changing business requirements. The functionality of the ZXTM product family is vertically-scalable enabling businesses to upgrade from load balancing (ZXTM LB) to a full application traffic management system (Zeus eXtensible Traffic Manager) as more enhanced features are required, all without complicated migration.
