Calculating Memory Usage

The amount of memory used by Directory and Resource Administrator varies depending on the enterprise structure. The following equations are meant to assist in calculating the average memory the Administration products will use in your environment. If you make frequent calls for large amounts of information, the corresponding memory usage will spike higher than values you calculete using the following equations.

Memory Calculation Equations

The following variables are used in equating cache memory usage:

• AvgName - Average bytes in name (user, computer, group, contact, or OU)
• AvgDesc - Average bytes in description (user, computer, group, contact, or OU)
• AvgSAM - Average bytes in SAM account name (user, computer, or group)
• AvgUPN - Average bytes in User Principal Name (user)

The following list shows the equations for calculating the memory used by the Administration products:

• Number of users x (54 + AvgName + AvgDesc + AvgSAM + AvgUPN) = User bytes
• Number of computers x (32 + AvgName + AvgDesc + AvgSAM) = Computer bytes
• Number of groups x (52 + AvgName + AvgDesc + AvgSAM) = Group bytes
• Number of contacts x (32 + AvgName + AvgDesc) = Contact bytes
• Number of OUs x (70 + AvgName + AvgDesc) = OU bytes
• User bytes + Computer bytes + Group bytes + Contact bytes + OU bytes = Total memory used

Example Memory Calculation

If the managed domains contain 3000 users with an average name of 12 bytes, an average description of 20 bytes, an average SAM account name of 8 bytes, and an average User Principal Name of 11 bytes, the total bytes of memory used for user accounts is calculated as follows:

 

3000 (54 + 12 + 20 + 8 + 11) = 315000

If the managed domains contain 200 computers with an average name of 12 bytes, an average description of 25 bytes, and an average SAM account name of 8 bytes, the total bytes of memory used for computer accounts calculated as follows:

200 (32 + 12 +25 + 8) = 154000

If the managed domains contain 700 groups with an average name of 8 bytes, an average description of 25 bytes, and an average SAM account name of 8 bytes, the total bytes of memory used for group accounts is calculated as follows:

700 (52 + 8 + 25 + 8) = 65100

If the managed domains contain 300 contacts with an average name of 14 bytes and an average description of 25 bytes, the total bytes of memory used for contact accounts is calculated as follows:

300 (32 + 14 + 25) = 21300

If the managed domains contain 100 OUs with an average name of 8 bytes and an average description of 12 bytes, the total bytes of memory used for OU accounts is calculated as follows:

100 (70 + 8 + 12) = 9000

The total number of bytes calculated by adding the totals for each object type. The total amount of memory used in the example, therefore, is calculated as follows:

315000 + 154000 + 65100 + 21300 + 9000 = 564400 (564KB)

Server Hardware Requirements
Element	Requirements
CPU	Intel Pentium III computer, 450MHz or higher (32-bit hardware only)
. RAM	384MB The amount of memory required depends on the number of objects in the managed domain. For more information about calculating memory usage, see "Calculating Memory Usage" below.
Drive Space	200MB and 200MB temporary space
Other Considerations	Application Event Log The Administration products record entries in the Windows 2000 application event log. You may need to increase the size of your application event log. Registry The Administration products require about 5MB of disk space for the security data stored in the Windows 2000 registry. Domain Files To improve performance, the Administration server caches trusted domain information in domain files stored on the Administration server computer. If there is insufficient disk space the Administration server logs warning messages in the event log and will not be able to load information from some trusted domains. These domains are marked Incomplete in the right pane of the MMC interface Domain files vary in size based on the number of user accounts, groups, OUs, and contacts in a domain. For example, a domain with 470 computers, 65 groups, and 3,000 users with the average user in 5 groups yields a domain file of 320KB. A domain with 10,000 users yields a domain file of 1MB.
