In-Depth Information
Specifying server i/o capacities are estimates with oracle. if you click the Specify Server i/o Capacity button,
you'll be presented with a dialog box that enables you to specify multiplier factors or absolute values to update the
capacities for all selected servers.
Note
For Consolidation Planner to make correct estimations on savings or resources, it is going to be based on the
amount of data collected. In the Data Collection section of the Create Consolidation Project screen, the administrator
can specify the minimum and maximum number of days that should be used to estimate consolidation. Like many
other tasks within Enterprise Manager, the collection of data is handled by a job that will be created. As part of the
data collection, the option to start data collection immediately or later can be specified.
The last step in creating a consolidation project is to specify whether the project should use any preconfigured
scenarios. By default, no scenarios are selected. However, a preconfigured scenario can be selected from three
options; these scenarios use the metric for CPU, Memory, and Disk Storage to analyze the consolidation project.
Figure 5-33 provides the breakdown of these scenarios.
Figure 5-33. Preconfigured scenarios
After selecting a preconfigured scenario, the project can be submitted and created. If the project is created
successfully, the Consolidation Planner page will reflect the project being created and the current status of the project.
At the bottom of the screen, you will also notice three tabs providing specific information on the project. These tabs
are General, Source Servers, and Source Workload.
The General tab gives you all the specific information related to the project, including the project name,
identification number, consolidation type, and current status of data collection. The Source Servers tab gives you
information similar to that presented when adding the source targets to the project. Items such as CPU utilization,
memory utilization, and disk storage are presented. What is interesting on this tab is the information that is provided
by telling you the start and end dates of data collection. The Source Workload tab gives you a 24-hour view, in a table
format, of the resources that are being measured for consolidation (see Figure 5-34 ). These can be viewed by using the
Resource Type drop-down menu.
