4.5.6 Guidelines for disk space requirements for the operation log database

The following describes the guidelines for disk space requirements for the operation log database on the management server and site server.

Guidelines for the management server

The following table shows the guidelines for disk space requirements for the operation log database (operation log database folder) based on the number of devices for which operation logs are acquired and the period of operation logs to be restored.

Number of managed devices	Required disk space (GB)
	Not restored	10 days#1	30 days#1	50 days#1	100 days#1	300 days#1	500 days#1
100	23	40	45	49	60	103	145
200	29	49	58	66	87	173	258
300	36	58	70	83	115	243	371
400	43	67	84	100	143	314	485
500	49	75	97	118	171	384	576
600	55	83	109	135	199	454	583
700	62	92	122	151	226	525	589
800	68	100	134	169	254	595#2	595#2
900	74	109	147	186	282	601#2	601#2
1,000	81	118	161	203	310	608#2	608#2
3,000	209	288	416	544	736#2	736#2	736#2

#1: The period of operation logs to be restored from the backup.

#2: This value applies when the number of records in the database reaches the maximum (approximately 500 million). Because the required space per record depends on the number of devices for which operation logs are acquired, the disk space required for the database varies.

Guidelines for the site server

The following table shows the guidelines for disk space requirements for the database folder based on the number of devices connected to the site server and the operation period.

Number of devices connected to the site server	Required disk space (GB)
	1 year	2 years	3 years	4 years	5 years
100	9	14	19	25	31
300	19	35	51	67	82
500	31	56	82	109	135
1,000	56	108	161	213	265

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