What software comprises Moab Cluster Suite?
Moab Cluster Suite consists of three components, Moab Workload Manager, Moab Cluster Manager and Moab Access Portal.
The three components work together creating a complete cluster management and administration resource. The main engine of the Suite is Workload Manager. To evaluate on your own cluster you at least need Workload Manager. Cluster Manager is the graphical administration tool that you can connect to Workload Manager or evaluate through an online demonstration cluster. Access Portal is an end-user submission portal that also connects to Workload Manager or you can evaluate through our online demonstration cluster.
Can I evaluate Moab if I do not have a cluster?
Yes. Moab Cluster Manager allows you to connect to our 256-node online demonstration cluster from your desktop. There you can view and demo most of Moab Cluster Managers capabilities. Cluster Manager online demonstration.
Moab Access Portal is also available through an online demonstration. You can view the features and usability of the end-user submission portal. Access Portal online demonstration
Can I evaluate Moab without affecting my workload?
Yes. There are two ways to do this:
You can install Moab Cluster Manager on your desktop and connect to our 256 node online demonstration cluster to view some of the capabilities, as well as view Moab Access Portal by connecting to the online cluster. Cluster Manager online demonstration and Access Portal online demonstration.
You can install Moab Workload Manager on you cluster, but set it to monitor in simulation mode (view the Simulation configuration demo). This mode will show what the Workload Manager would do to your workload, but without actually affecting it. Installing Workload Manager on your cluster will also allow you to use Moab Cluster Manager and Moab Access Portal on your cluster. Workload Manager evaluation

Yes. You can also add an additional layer of security between the end-user's browser and Access Portal by encrypting all data in a SSL connection.
How do I uninstall the Moab evaluation to install the production version?
