4.5.2 Maximum disk space requirements for the management server in a single-server configuration system

Database folder

The following information used by the management server:

• Security policy

• Group

• Agent settings

Stored until deleted.

0.5 GB

The following asset information:

• Hardware asset information

• Managed-software information

• Software license information

• Contract information

Stored until deleted.

5 GB

Actually, the disk space might exceed 5 GB because the folder size increases with the number of registered items.

We also assume that the following information items have been registered, each item has no additional management items, and many large files are not registered. To register many large files to be managed, allocate sufficient free space separately.

• Hardware asset information: 20,000 items

• Managed-software information: 500 items

• Software license information: 100 items

• Contract information: 100 items

Device information for managed devices

Stored until deleted.

10 GB

This is based on the assumption that 10,000 devices are managed.

Revision history

Stored until the used disk space reaches the maximum. If the maximum space is exceeded, entries are deleted beginning from the oldest.

Approximately 7 GB

This is based on the assumption of a system with 10,000 managed devices, in which the number of device information changes recorded daily per device is the total of the following:

• Number of changes recorded in day-to-day operation: 14

• Number of invalid changes: 0.1 (one invalid change per device in 10 percent of devices)

Events

Stored until the used disk space reaches the maximum. If the maximum space is exceeded, events are deleted, beginning from the oldest.

(250 x 10,000 licenses owned + 10,000) x 1.5 KB = Approximately 4 GB

This is based on the assumption that the following conditions exist:

• 250 events are generated for one managed device per day

• The number of owned licenses (managed devices) is 10,000.

• 10,000 events are generated per day irrespective of the number of managed devices.

• One event requires 1.5 KB of disk space.

Reports for the specified storage period

Stored for the specified number of years (from 1 to 10) as the storage period.

10 GB

This is based on the assumption that reports are stored for 10 years.

Approximately 10 GB

This is based on the assumption that 1,000 10 MB packages are registered.

Data folder

Packages used by the distribution function

Stored until deleted.

Operation log database folder

Operation logs when only operations closely related to information leakage are logged (operation logs that can be referenced in the operation log list and that have not been restored from the backup folder)

Stored until either of the following occurs, whichever occurs first. If automatic backup setting is enabled, old operation logs are automatically saved in the operation log backup folder when they are deleted.

• The number of operation logs reaches the maximum.

  The maximum number of operation logs is obtained by multiplexing the number of computers with agents installed by 2,700 (logs per device per day) and then by 30 (days). If the maximum number is exceeded, operation logs are deleted, beginning from the oldest.

• Operation logs for 500 days are acquired.

  Operation logs which have been stored beyond 500 days are deleted, beginning from the oldest.

• Until the number of operation logs reaches the maximum:

  30 days x 3,000 managed computers x 80 KB = 7.2 GB^#1

• Until the operation logs for 500 days are acquired:

  7.2 GB

Operation logs when all operations are logged (operation logs that can be referenced in the operation log list and that have not been restored from the backup folder)

Stored until either of the following occurs, whichever occurs first. If automatic backup setting is enabled, old operation logs are automatically saved in the operation log backup folder when they are deleted.

• The number of operation logs reaches the maximum

  The maximum number of operation logs is obtained by multiplexing the number of computers with agents installed by 2,700 (logs per device per day) and then by 30 (days). If the maximum number is exceeded, operation logs are deleted, beginning from the oldest.

• Operation logs for 500 days are acquired.

  Operation logs which have been stored beyond 500 days are deleted, beginning from the oldest.

• Until the number of operation logs reaches the maximum:

  30 days x 3,000 managed computers x 1.5 MB = 135 GB^#2

• Until the operation logs for 500 days are acquired:

  135 GB

Operation logs restored from the backup folder for reference in the operation log list

Stored until deleted.

500 days x number of computers with agents installed x 1.5 MB^#3

Operation log backup folder

Automatically backed-up operation log

If automatic backup setting is enabled, excess operation logs are stored from the operation log database folder once a day. These logs are stored until deleted.

If you attempt to reference the restored operation logs in the operation log list, they are restored in the operation log database folder, but the operation logs in the operation log backup folder are not deleted.

There are no restrictions on the disk space.^#2

Set up the backup folder by referring to the value obtained as follows: Storage period (days) defined by the administrator x number of computers with agents installed x 1.5 (MB per device per day) x 0.5 (compression level).

Revision history output folder

Archived revision history

When you enable output of the revision history archive, revision histories are output to this folder as CSV files at regular intervals.

Approximately 10 GB

This is based on the assumption that 10,000 devices are managed, and the revision history archive spans five years.
