14.2 Filrsearch Sizing

The amounts shown in “Worksheet 22 - Filrsearch Appliances” are explained in Table 14-2. As before, you can adjust the numbers shown with solid or small-dotted borders. Numbers in cells with black dashes are calculated based on information you entered previously and you should not modify them directly.

Table 14-2 Filrsearch Appliance Sizing Guidelines

Item	Recommendations and Guidelines	Planning Worksheet Example
/ (System Disk)	20 GB fixed
/vastorage	Use the following guidelines when planning /vastorage for a Filrsearch appliance. Allocate 10 GB as a base amount. Allocate 11 KB per content-searchable file. Allocate 5 KB per name-search-only file.	The worksheet calculates this as follows: It includes 10 GB as a base disk amount. It multiples the total number of content-searchable files by 11 KB (.000011 GB). It multiples the total number of name-search-only files by 5 KB (.000005 GB). It multiplies the above by two in case index optimization is required.
/var	Use the following guidelines when planning /var for a Filrsearch appliance. Include 4 GB for system logs. Include space for core dumps by multiplying the total RAM allocation by 3.	The worksheet calculates this as follows: It automatically includes 4 GB for system logs. It multiplies the total RAM by 3 to accommodate core dumps.
RAM	Use the following guidelines when allocating RAM for a Filrsearch appliance. Plan to allocate 30% of amount calculated for /vastorage. You also need to adjust the JVM Heap size to be 50 - 60% of total RAM.	The worksheet calculates this as follows: It multiples the calculated amount for /vastorage by .3 to get 30% and displays the result as a whole number in the RAM (GB) cell. It then multiples the number in the RAM (GB) cell by .6 to get 60%.
CPUs	The default allocation at install time is 2 CPUs. However, large installations usually require 4 CPUs.	The planning worksheet reflects a large installation, so 4 CPUs are planned.
