Viewing the Final Output Using the GUI

After the analysis is complete, the Presenter button is enabled.

Select any of the analyzed trace file, and click Presenter, to view the graphical representation of the analyzed workload.

Based on the analyzed workload, the following summary on the console provides the three different situations when the analyzer is run in the GUI.

Analysis 1

Upon successful completion of the IO trace analysis, the Nytro Predictor tool shows the statistics providing enhanced understanding of the application IO workload, and charts substantiating the predicted application performance acceleration.

Workload Characteristics

Workload is characterized by read and write mix or percentage, and by the frequently accessed hot data size of the application.

The hot data size provides accurate insight into the size of the application’s most frequently accessed data. This size is determined by the total amount of cache fills required to move the most frequently accessed application data to Nytro accelerated storage providing the highest level of cache hits and the highest potential for application performance acceleration.

Cache Hits and Fills

The cache hits and fills provides the Nytro Predictor analysis statistics supporting the predicted application performance acceleration improvement. The subsequent sections provide a more detailed description of this chart.

If the storage type is SAN, the following figure appears showing the benefits of using Nytro XD.

Figure 7. Presenter Status – Nytro XD Benefits

If the storage type is DAS, the following figure appears showing benefits of using Nytro MegaRAID or Nytro XD.

Figure 8. Presenter Status – Nytro MegaRAID Benefits

NOTE  The preceding figure reflects the Nytro MegaRAID in the Write Back (WB) write policy with virtual disks in the Write Through (WT) write policy.

Analysis 2

The following dialog appears indicating that the workload might not benefit from the Nytro Predictor software tool. You might have to collect the I/O traces for a longer duration, and then run the Nytro Predictor software tool again.
