#1 If you specified a value for Capacity to be added to the cache during management server setup to improve the performance of the operation log search function, the specified value (a maximum of 16 GB) must be added.
#2 If there are 30,000 to 50,000 managed computers, with 10 to 20 users simultaneously manipulating the operation windows, use an additional 512 MB of memory. For details, see the section describing the settings for simultaneously manipulating the operation windows with 10 to 20 users in the JP1/IT Desktop Management 2 Configuration Guide.

The required value can be calculated from the following formula: 20 + 0.002 x a MB a: number of displayed data items The number of displayed data items is the total of the data items (shown below) that are displayed in Remote Install Manager windows. If you want to display more than one of the same windows, multiply the number of data items by the number of those windows.

If you added the capacity of the database cache to improve the performance of the operation log search function, the value specified for addition (a maximum of 16 GB) must be added. |
Drive of the database storage folder (database capacity) |
|
Drive on which the data folder is stored |
A value equal to or greater than the sum of the following values:
|
Drive of the operation log backup folder |
You must estimate the data capacity#4 appropriate for the operation. #7 |
Drive on which the revision history output folder is stored |
You must estimate the data capacity#5 appropriate for the operation. |
#1: For details about the data capacity required for the operation log database, see 4.5.4 Guidelines for disk space requirements for the operation log database. If the number of managed computers is in the range from 10,000 to 30,000, Hitachi recommends that you use a dedicated physical disk for the operation log database.
#2: For details about the data capacity required for the revision history database, see 4.5.7 Guidelines for disk space requirements for revision history database.
#3: For details about the data capacity required for the data folder, see 4.5.5 Guidelines for disk space requirements in the data folder for acquiring operation logs.
#4: For details about the data capacity required for the operation log storage folder, see 4.5.3 Guidelines for disk space requirements for operation log backup folder.
#5: For details about the data capacity required for the revision history output folder, see 4.5.6 Guidelines for disk space requirements for revision history archive.
#6: If you added the capacity of the database cache to improve the performance of the operation log search function, the value specified for addition (a maximum of 16 GB) must be added.
#7: When the number of managed computers is 30,000 to 50,000 and you want to collect operation logs, you must use a multi-server configuration. Because the primary management server does not collect the information, the capacity for operation logs is not included in the estimate.
