Calculation and changing of disk space for storing Administration Server data

Administration Server data includes the following objects:

• Information about assets (devices).
• Information about events logged on the Administration Server for the selected client device.
• Information about the domain in which the assets are included.
• Data of the Application Control component.
• Updates. The shared folder additionally requires at least 4 GB to store updates.
• Installation packages. If some installation packages are stored on the Administration Server, the shared folder will require an additional amount of free disk space equal to the total size of all of the available installation packages to be installed.
• Remote installation tasks. If remote installation tasks are present on the Administration Server, an additional amount of free disk space equal to the total size of all installation packages to be installed will be required.

Calculation of the minimum disk space for storing Administration Server data

The minimum disk space required for storing the Administration Server data can be estimated approximately by using the formula:

(724 * C + 0.15 * E + 0.17 * A + U), KB

where:

• C is the number of assets (devices).
• E is the number of events to store.
• A is the total number of domain objects:
  • Device accounts
  • User accounts
  • Accounts of security groups
  • Organizational units
• U is the size of updates (at least 4 GB).

If domain polling is disabled, A is considered to equal zero.

The formula calculates the disk space required for storing typical data from managed devices and the typical size of updates. The formula does not include the amount of disk space occupied by data that is independent of the number of managed devices for the Application Control component, installation packages, and remote installation tasks.

Changing of the disk space for storing the Administration Server data

The amount of free disk space allocated to store the Administration Server data is specified in the configuration file before the deployment of Kaspersky Next XDR Expert (the ksc_state_size parameter). Take into account the minimum disk space calculated by using the formula.

To check the disk space used to store the Administration Server data after the deployment of Kaspersky Next XDR Expert,

On the administrator host where the KDT utility is located, run the following command:

./kdt invoke ksc --action getPvSize

The amount of the required free disk space in gigabytes is displayed.

To change the disk space used to store the Administration Server data after the deployment of Kaspersky Next XDR Expert,

On the administrator host where the KDT utility is located, run the following command and specify the required free disk space in gigabytes (for example, "50Gi"):

./kdt invoke ksc --action setPvSize --param ksc_state_size="<new_disk_space_amount>Gi"

The amount of free disk space allocated to store the Administration Server data is changed.
