- Visit http://www.intel.com/storage-snapshot for the latest product download package.
- Download the Linux or Windows collector file to your local system.
- Extract the contents to a writeable location on your local system.
- Windows:C:\Program Files (x86)\IntelSWTools\VTune Profiler\storage_snapshot
- Identify a typical workload for the system under analysis. Systems in a data center or those running a continuous workload could use a sample time period.
- Collect data.If this is the first time you are running the analysis, make sure your system meets the prerequisites listed in the readme file.On Linux*:
- Open a command prompt.
- Run thesps-start.shscript to begin collecting data.The collected data is added to afile in the current directory.<hostname>_<timestamp>.dat
- Run thesps-stop.shscript to stop collecting data and close the result file.
- In Windows Explorer, right-click thesps-vars.cmdscript and selectRun as administrator. A command prompt with Administrative privileges opens and runs the script to sets up the data collection environment. Alternatively, run"from a command prompt with Administrative privileges.<install-dir>\sps-vars.cmd"You may need to change your PowerShell execution policy to RemoteSigned before running the Storage Performance Snapshot scripts. Additional information on PowerShell execution policies and how to manage them is available from https://technet.microsoft.com/library/hh847748.aspx.
- Run thesps-start.cmdscript to begin collecting data.
- Run thesps-stop.cmdscript to stop collecting data.The collected data is added to afile in the current directory.<hostname>_<timestamp>.dat
- View the report in a supported web browser.
- If the offline viewer is installed on your local system, open thefile.<install-dir>/storage_snapshot/index.htmlIf the offline viewer is not installed on your local system, go to the main page for the Storage Performance Snapshot tool in your web browser: http://www.intel.com/storage-snapshot.A list of supported browser versions is available from theindex.htmlpage.
- ClickSelect snapshot file to view.
- Browse to the.datresult file and clickOpen.The results are displayed in your browser. Results remain local to your system and are not uploaded to Intel servers.
- Analyze the data shown in the report.A short video demonstration of the Storage Performance Snapshot is available at https://software.intel.com/en-us/videos/meet-the-new-intel-storage-performance-snapshot-tool (4:40 minutes).
- Determine appropriate next steps based on result analysis. Common next steps may include working with a system analyst to evaluate the results, reviewing user forum posts or creating your own post to discuss your findings, or conducting additional analysis withIntel® VTune™.ProfilerA user forum for all Intel Performance Snapshot tools is available from https://software.intel.com/en-us/forums/intel-performance-snapshot.
- The thread is idle due to networking bottlenecks or load imbalance. In this case, improving storage performance will not improve application performance.
- The thread is blocked behind threads waiting for IO on another core. In this case, improving storage performance may translate to improved application performance.
