4.5.9 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. These guidelines vary depending on the types of operation logs to be acquired.

When all operations are logged(management server)

Number of managed devices	Recommended disk space (GB)
Number of managed devices	1 year^#	2 years^#	3 years^#	4 years^#	5 years^#
100	97	126	155	184	214
500	267	412	556	701	846
1,000	478	768	1,058	1,347	1,638
2,000	901	1,474	2,063	2,640	3,223
3,000	1,322	2,192	3,066	3,931	4,806

#: Operation log storage period. For calculation of the amount of data, one year is handled as 365 days.

When only operations closely related to information leakage are logged (management server)

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	70	71	72	74	76
500	129	135	142	148	155
1,000	201	215	228	241	255
2,000	346	376	401	428	456
3,000	489	535	572	613	655

#1: The value is based on the assumption that the environment shown below is used, a constant amount of data is generated per day, and the data is accumulated every day.

#2: Operation log storage period. For calculation of the amount of data, one year is handled as 365 days.

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, 2,700 operation logs are acquired for one device. 30 (days) is specified for Maximum restore period for operation logs used for browsing the past operation logs.
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.
Distribution	10 GB of data is registered for packages.
Event	250 events are generated for one managed device per day.

When all operation logs are collected on the site server

Number of devices connected to the site server	Recommended disk space (GB)
Number of devices connected to the site server	1 year	2 years	3 years	4 years	5 years
100	33	63	92	123	153
500	153	300	447	596	744
1,000	300	595	892	1,188	1,483

Note: The value is based on the assumption that 2,700 operation logs are generated for one device per day.

When only operation logs closely related to information leakage are collected on the site server

Number of devices connected to the site server	Recommended disk space (GB)
Number of devices connected to the site server	1 year	2 years	3 years	4 years	5 years
100	6	7	10	11	12
500	12	20	27	35	43
1,000	20	35	51	66	82

Note: The value is based on the assumption that 2,700 operation logs are generated for one device per day.
