Ingestion procedure
Ingest data into a workload as follows:
1. Ingest one or more files:
a. Choose
Generated from Imported Data
in the
Workload Source drop-down menu. The Select Imported Data list box is displayed.
|
Note: Your system model can ingest data from any system type. (See
Table 11
for a list of valid file types for import). It is not a problem if the type of device whose record you are importing differs from the device type in your new system model.

Figure 101 Select Imported Data dialog box
b. Select the checkbox for each files that you want to ingest. Choose files with the relevant
Type of statistics (Performance or IBM Z RMF statistics) and other attributes. Be sure to consider the
Suitability Index rating of the files. (See
“What makes a data report suitable?”.)
c. Click OK. The Workload Source message box prompts you to confirm your
action, because many fields in your workload will be updated:
|
Are you sure you want to generate this workload from Imported Data?
All previously entered workload characteristics will be discarded. Continuing will save this workload automatically. |
d. Click Continue. The Workload goes into “Analyzing” mode while Storage
Modeller analyzes the imported data file. This analysis phase can take many minutes and in some cases hours.
|
Tip: You can Save your workload immediately. That way, you can continue to work on other systems and projects in
Storage Modeller. Ingestion analysis continues to run in the background. After you click Save, the
Performance / Workloads
tab is displayed, and the status of this workload is “Analyzing”.

Figure 102
shows the section of a Workload form that displays a completed ingestion. The section reminds you of the characteristics of the imported files that you ingested.
2. (Optional) Take further ingestion-related actions, as needed, in the
Workload section that is shown in Figure 102:
a. Click Add/Change to add or change the records that your Workload ingests.

3. (Optional) After ingestion is complete, tweak the statistical data of the
workload to respond to any special customer requirements. For details, see
“Customizing the result of an ingestion in the Workloads form”.
a. Use the Selected Peak menu to change the default metric that Storage
Modeller references. The tool references Total I/O Rate by default.
Any type of peak that you select becomes the reference point for assessing your model. You can select a peak metric that matters most to your customer, such as data transfer rate.

b. Future growth (%): Enter a percentage value that reflects customer
expectations for future growth, for example, a 25% growth in system loads. The statistical values for the workload are increased accordingly.
4. Specify an Easy Tier Skew factor as described in the regular instructions
for workloads. See Step
16 on page 124
in
“Adding a workload”.

Tip: See
Table 19 on page 277,
which describes all fields of the Workloads form including Easy Tier Skew.

5. Click Save to save your newest settings for the workload.
The Performance / Workloads tab is displayed, with a listing of all workloads for your project. Here, you typically click the Solve All button to run the listed workloads against the systems in your project for which you have defined workloads.
