The disk performance of the Manager affects the performance of each display function (the Monitor view, the Drill Down view and the Report view).

If Systemwalker Centric Manager is installed on the same machine as the Manager for this product, it is recommended that an environment that takes disk performance into account be prepared (by preparing separate disk partitions, for example).

3.1.1.1 How to estimate the amount of space required for the performance database 

Managers require disk space for a performance database.

The size of this database depends on the number of Agents and on the number of instances of the resources being managed.

To estimate the disk space required:

1. First, calculate how much data will be collected by each of the Agents on the servers being managed.
2. Next, calculate the total of the results from step 1. This total gives the disk space required for the database.

This section explains how to calculate the amount of data that will be collected by a single Agent. Make this calculation for each instance of the resources that the Agents are managing. Multiply the number of instances of each resource by the coefficient shown in the table below, and add up these totals.

For example, to estimate the amount of data required to manage a server with Symfoware Server installed, determine the totals for each resource shown in the "OS (Windows)" and "Symfoware Server" rows of the following table by multiplying the number of instances by the corresponding coefficient, and then add up these totals.

Managed resource	Instance	Coefficient (MB)
OS (Windows)	1	11.8222
	Number of logical drives	6.2062
OS (Solaris)	1	39.7501
	Number of (mounted) logical disks	3.1031
OS (Linux)	1	39.7501
	Number of (mounted) logical disks	3.1031
Symfoware Server	Number of RDB systems	3.1031
	Number of RDB systems number of DB spaces	3.1031
Oracle Database Server	Number of instances (SIDs)	22.3626
	Number of instances (SIDs) number of table spaces	3.1031
