Hybrid Tagged Performance Test (LOGO)

  • Artikel

This test is testing for performance of I/O with priority. This is to satisfy the requirement that a read or write that has a priority assigned must not incur a latency penalty larger than 10% of an identical I/O without priority information.

Additional documentation

Tests in this feature area might have additional documentation, including prerequisites, setup, and troubleshooting information, that can be found in the following topic(s):

Running the test

Before you run the test, complete the test setup as described in the test requirements: Hard Disk Drive Testing Prerequisites.

Troubleshooting

For troubleshooting information, see Troubleshooting Device.Storage Testing.

Hybridflt.sys must be installed for this test to work properly.

More information

The test should automatically turn the hybrid information on before checking the logs if it was not on already.

In general, the test will do the following:

  1. Generate a baseline for an I/O situation without priority

  2. Generate a baseline for an I/O situation without priority

  3. Compare against the baseline. If the average is more than 10% worse or if a single I/O is greater than 100 milliseconds, the test case will fail.

The scenarios that are run:

  1. Sequential 128k Read/Write from rotational media

  2. Sequential 128k Read/Write from cache

  3. Random 4k Read from rotational media

  4. Random 4k Read from cache

  5. Random 4k Write to rotational media

  6. Random 4k Write to cache

To ensure that the cache is in a clean state before running a specific scenario, the test will turn the cache off and on before running each test case.

Use the Command Syntax section to execute a specific test case.
