4.5.8 Guidelines for recommended disk space

The following describes the guidelines for the recommended disk space for all data (including operation logs) managed by JP1/IT Desktop Management 2. These guidelines vary depending on the types of operation logs to be acquired.

For the management relay server, add disk space for the information to be sent to the higher management server (24 GB), to each recommended disk space value in the guidelines below.

When all operations are logged

Number of managed devices	Recommended disk space (GB)^#1
Number of managed devices	1 year^#2	2 years^#2	3 years^#2	4 years^#2	5 years^#2
100	240	242	243	245	247
500	259	267	275	283	291
1,000	281	297	313	329	345
2,000	371	403	435	467	499
3,000	464	512	560	608	656
5,000	645	725	805	885	965
10,000	1,218	1,374	1,538	1,698	1,858
30,000	3,164	3,644	4,124	4,604	5,084
100,000	3,417	3,897	4,377	4,857	5,337
300,000	4,137	4,617	5,097	5,577	6,057

#1: The value is based on the assumption that a constant amount of data is generated per day, and the data is accumulated every day according to an assumed environment.

#2: Operation log storage period. For calculation of the amount of data, one year is handled as 240 days (20 business days per month).

When only operations closely related to information leakage are logged

Number of managed devices	Recommended disk space (GB)^#1
Number of managed devices	1 year^#2	2 years^#2	3 years^#2	4 years^#2	5 years^#2
100	236	236	236	236	236
500	237	237	238	238	239
1,000	238	239	240	241	242
2,000	241	243	245	247	249
3,000	246	249	252	254	257
5,000	251	256	261	266	271
10,000	386	396	405	415	425
30,000	614	643	672	701	730
100,000	867	896	925	954	983
300,000	1,587	1,616	1,645	1,674	1,703

#1: The value is based on the assumption that a constant amount of data is generated per day, and the data is accumulated every day according to an assumed environment.

#2: Operation log storage period. For calculation of the amount of data, one year is handled as 240 days (20 business days per month).

The following table describes the assumed environment used for calculating the recommended disk space.

Item	Assumed environment
Device	100 types of groups, including department and location, are created. The number of devices excluded from management is 15% of the number of managed devices. 300 software products (installation software) are installed on one managed device. One managed device has 300 Windows updates applied. One managed device has 100 Windows updates that have not been applied yet.
Operation log	If only operations closely related to information leakage are logged, 120 operation logs are acquired for one device. If all operations are logged, 2,000 operation logs are acquired for one device. 30 (days) is specified for Period for storing automatically restored operation logs. Operation logs for 200 computers for 3 months (20 business days per month) are manually restored. However, if there are 100 managed computers, operation logs for 100 computers are manually restored. Periodic export of the operation logs is not performed. In the Capacity to be added to the cache of setup, specify 1 GB for every group of 2,500 managed computers.
Asset	The number of registered items of hardware asset information (excluding USB devices) is twice as many as the number of managed devices. 100 items of hardware asset information (USB device) are registered. 500 items of managed-software information are registered. 100 items of software license information are registered. 100 items of contract information are registered. We assume that many large files are not registered for each asset information item. To register many large files to be managed, allocate sufficient free space in addition to the disk space shown in the two tables above.
Revision history	Periodic output of the revision histories to be restored is not performed.
Distribution	10 GB of data is registered for packages.
Event	250 events are generated for one managed device per day.
