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	153	155	158	161	163
500	178	187	196	205	214
1,000	209	226	243	260	277
2,000	272	305	338	371	404
3,000	334	383	432	481	530
5,000	459	540	621	702	783
10,000	772	933	1,094	1,255	1,416
30,000	2,024	2,505	2,986	3,467	3,948

#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	147	148	149	150	151
500	149	151	152	154	155
1,000	152	154	156	158	160
2,000	157	160	163	166	169
3,000	162	166	170	174	178
5,000	173	179	185	190	196
10,000	199	210	221	231	242
30,000	305	335	365	394	424

#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.
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.
