Question/Problem Description

What additional licences are required when deploying OpenEdge on Fault-Tolerant or High-Availability environments?

What additional licences are required when deploying OpenEdge on a VMWare vSphere Fault-Tolerant (FT) environment?
What additional licences are required when deploying OpenEdge on a VMWare vSphere High-Availability (HA) environment?

Is a disaster recovery (DR) license required in Fault-Tolerant or High-Availability environments.

Steps to Reproduce

Clarifying Information

High Availability Solutions

High availability solutions traditionally consist of a set of loosely coupled servers which have failover capabilities. Each system is independent and self-contained, yet the servers are health monitoring each other and in the event of a failure, applications will be restarted on a different server in the pool of the cluster. Windows Server Failover Clustering is an example of an HA solution. HA solutions provide health monitoring and fault recovery to increase the availability of applications. A good way to think of it is that if a system crashes (like the power cord was pulled), the application very quickly restarts on another system. HA systems can recover in the magnitude of seconds, and can achieve five 9’s of uptime (99.999%)… but they realistically can’t deliver zero downtime for unplanned failures. They also are flexible in that they enable recovery of any application running on any server in the cluster.

Fault Tolerant Solutions

Fault tolerant solutions traditionally consist of a pair of tightly coupled systems which provide redundancy. Generally speaking this involves running a single copy of the operating system and the application within, running consistently on two physical servers. The two systems are in lock step, so when any instruction is executed on one system, it is also executed on the secondary system. A good way to think of it is that you have two separate machines that are mirrored. In the event that the main system has a hardware failure, the secondary system takes over and there is zero downtime.

Cause

Resolution

In High-Availability (HA) and Fault-Tolerant (FT) environments, since those architectures provide failover or redundancy capabilities, a Disaster Recovery(DR) license is required, should you own single server licenses (concurrent, CPU, agent).

However, a Disaster Recovery(DR) license is not required under a multi-server license such as "Named User License".
