Based on the defined files and folder, indexing, and search requirements, define the estimated space needed for the Filr, MySQL, and Search servers. Check the Novell Filr 1.0.1 Installation and Configuration Guide for the latest data and start with the recommended minimums. Use the following as a guide:
When using multiple appliances for production deployments: 8 GB memory and 2 CPUs. At least 66% of the memory should be dedicated to the Java processes [heap]. More memory might be required.
If memcached has been offloaded to the Filr Search appliances, or elsewhere, then it might be possible to dedicate as much as 75% of the memory to the Java processes.
