Process overview for data ingestion
You import data reports for use in Workloads and Safeguard Copy (SGC) Capacity Sizing through this general process:
1. Import: You import data files from existing systems into Storage Modeller to support performance modeling. See Table 11 for valid file types.
 
Note: The data files that you import are valid to use in projects for any type of device in Storage Modeller, regardless of the type of device that generated the data files.
Table 11 Valid file types in the Import Data dialog box
“Import Type” options
File types
Storage Insights Performance statistics
*.csv file (or ZIP files containing multiple CSV files1) from these sources:2
 – IBM Storage Insights
 – IBM Storage Control
DS8000 Performance Summary statistics
*.csv file (or ZIP files containing one or more CSV files3) from IBM DS8000 user interface with version 9.2. code bundle 89.21.25.0 or later.
IBM i Disk Performance statistics
*.csv file (or ZIP files containing multiple CSV files).
IBM Z RMF statistics
*.trs files from the IBM Z Resource Measurement Facility (RMF), in IBM Z tersed format.5
1 The *.csv files in a *.zip file must come from a single type of storage system. Otherwise, the import process cannot be completed.

2 Storage Modeller validity checks include a requirement that the file name retain the naming convention of the source. For example, IBM Storage Control names files as in this example:
PerfReport_CSS21-EZB2_Volumes_20200202-011900_36hrs0mins.csv
This requirement also applies to *.csv files that are stored inside a *.zip file.

3 If the version is older than the specified version (9.2. code bundle 89.21.25.0 or later), the file import will fail.

4 These files might contain statistics for multiple storage systems. Storage Modeller creates a separate imported Data file for each system.
Note: For IBM i systems, Storage Modeller accounts for internal, direct-attached disks (DAS) and also creates a separate imported data file.

5 These files might contain statistics for multiple storage systems. Storage Modeller creates a separate Imported Data entry for each system. The *.trs files are generated by processing the dumped RMF records through the native z/OS AMATERSE utility.

2. Ingest:
a. Select: Based on Storage Modeller’s “suitability” analysis, you choose specific data files to ingest for a Workload in a specific project. (See “What makes a data report suitable?”)
b. Analyze: Storage Modeller analyzes the imported data and identifies baseline statistics from existing systems. These baseline statistics are integrated into the Workload to provide a point of reference for assessing your new model.
3. (Optional) Customize: You tweak optional Workload parameters.
You cannot modify the set of baseline statistics. However, you can tweak key Workload parameters to address customer concerns. For example, customers often want to model growth in system loads. See “Customizing the result of an ingestion in the Workloads form”.
4. Report: Click a solve button to run the completed Workload against your model, and view the resulting Performance reports. Based on “suitable” imported data, Storage Modeller generates insightful performance assessments for your model.
