14.1 Filr Sizing

The amounts shown in “Worksheet 21 - Filr Appliances” are explained in Table 14-1. 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 14-1 Filr Appliance Sizing Guidelines


Recommendations and Guidelines

Planning Worksheet Example

  • / (System Disk)

  • 20 GB fixed

  • This is set at 20 GB

  • /vastorage

A large, Filr-clustered appliance store the following in /vastorage:

  • Configuration files that are used for appliance upgrades.

  • Ganglia files that store monitoring information.

In most cases, 10 GB should be more than sufficient.

  • The worksheet assumes that 10 GB is sufficient.

    You can input a different number if desired.

  • /var

Filr appliances store the following in /var:

  • System event logs

    • The maximum size is 100 MB per log file.

    • The system automatically deletes log files older than 30 days.

    • Therefore, log files are basically capped at 3 GB but the worksheet allows for 4 GB as a buffer.

  • Memory core dumps

    Micro Focus recommends reserving space for three core dumps, so total RAM times 3

The worksheet calculates this as follows:

  1. It automatically includes 4 GB for system logs.

  2. It multiplies the total RAM by 3 to accommodate core dumps.

  • RAM

Use the following guidelines when planning RAM for Filr appliances:

  • No less than 8 GB should be allocated. (12 GB is the default)

  • If 8 is used as the base, then 1 GB should be added for each increment of 2,000 users over 2,000.

The worksheet calculates total RAM required as follows:

  1. It includes 8 GB as the base amount.

  2. It takes the total user count, subtracts 2,000, and divides the remainder by 2,000.

  3. It then adds the results from the two steps above and displays it as a whole number.

  • CPUs

  • 4 CPUs is standard.

  • The worksheet uses the default.

    You can input a different number if desired.
