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.

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	214	222	230	238	246
500	220	228	236	244	252
1,000	236	252	268	284	300
2,000	281	313	345	377	409
3,000	343	391	439	487	535
5,000	464	544	624	704	784
10,000	825	985	1,145	1,305	1,465
30,000	2,048	2,528	3,008	3,488	3,968

#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	205	206	206	207	208
500	206	206	207	207	208
1,000	207	208	209	210	211
2,000	209	211	213	215	217
3,000	212	215	218	221	224
5,000	216	221	226	232	237
10,000	284	294	304	314	325
30,000	334	365	395	426	457

#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.
