The following sections are included only as background information. No planning steps are included in them.
Micro Focus recommends having at least two Filr servers in a large, expandable deployment for basic performance and high-availability. You can add more as your deployment grows through your initial pilot to a phased-in production rollout.
Determine whether a hardware solution (such as an application delivery controller or L4 switch) or a software solution (such as NetIQ Access Manager, Apache, and so forth) will be used to front the Filr servers.
Micro Focus also recommends connecting a third Filr Appliance to the shared storage and not fronting it with a load balancer. This appliance can then be used for dedicated administration and Net Folder indexing and synchronization.
Having functional search appliances and the services they provide is vital to the health of the system.
Micro Focus recommends having two Search/Index servers for redundancy (fault tolerance) purposes. Having more than two is not recommended or needed, because there are no performance gains associated with multiple Filr Search appliances.
By using two Search Appliances, you can perform re-index operations at separate times, thus preventing the clients from re-downloading all their data. For instructions, see in the Filr 3.4: Maintenance Best Practices Guide.
