A.2 All-in-One Appliance Planning

As noted elsewhere, you can adjust the numbers shown with green borders. Data numbers in white cells are fixed and should not be changed. Cells with black dashes are calculated based on information you entered previously and you should not modify them directly.

Table A-2 Using Worksheet 10-a - All-in-One Appliance

Item

Recommendations and Guidelines

Worksheet Calculations and Examples

  • / (System Disk)

  • 20 GB fixed

  • This is set at 20 GB. You cannot alter the size.

  • /vastorage

An all-in-one appliance stores the following in /vastorage:

  • Configuration files that are used for appliance upgrades.

  • Ganglia files that store monitoring information.

  • Attachments that users upload to share.

The worksheet calculates this as follows:

  • It automatically includes 10 GB for configuration and Ganglia files.

  • It includes 40 GB as a base database amount.

  • It adds the user-generated storage total on Worksheet 6 - Gen’d Storage and Limits.

  • It multiples the total number of users by 20 KB (.000020 GB) and adds that to the total.

  • /var

TeamWorks 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 and adds it to the system log amount.

  • CPUs

  • 4 CPUs is the standard.

  • The worksheet uses the default.

    You can input a different number if desired.

  • RAM

Use the following guidelines when planning RAM for an all-in-one appliance:

  • No less than 16 GB should be allocated.

The worksheet calculates total RAM required as follows:

  1. It includes 16 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.
