Resource based load balancing
2X LoadBalancer intelligently distributes the load on the Terminal Server machine which has the least usage. By retrieving information about the Terminal Servers' resource usage before establishing the connection, it is able to determine the best Terminal Server to handle the incoming session. By contrast, network load balancing in Windows Server simply distributes connections on a round robin basis, independent of the server load.
redundancy of Terminal Servers
2X LoadBalancer first checks whether the terminal service of a particular server is responding before forwarding a connection to it. This allows you to ensure complete redundancy of each Terminal Server. By contrast, network load balancing in Windows Terminal Server just checks if the machine is alive: If the terminal service is not responding the user’s connection will be forwarded regardless, thus resulting in the user not being able to connect.
Reconnects users to disconnected sessions
2X LoadBalancer also checks if a user has a disconnected session on any of the servers and if so, reconnects them to the right server. No need for Windows 2000 Advanced Server or Windows 2003 Enterprise Server with session directory - Use standard server licenses and save thousands of dollars in licensing fees and hours of installation & administration time.
Firewall friendly, end to end SSL encryption
When used in SSL Gateway mode, the 2X LoadBalancer provides end-to-end SSL encryption to your terminal servers. This not only greatly enhances security but also gives you a firewall/proxy friendly solution with true SSL/HTTPS capabilities.
