Due to the success of the Jetstress 2010 field guide, we have decided to continue the tradition by releasing an updated version of the guide for Jetstress 2013 . As with the previous version, the aim of the document is as follows:
Explain how Jetstress works.
Provide storage validation planning and configuration guidance.
Provide Jetstress results interpretation guidance
So, what’s changed? Well, the good news is that Jetstress 2013 is very similar to Jetstress 2010. There are some modifications to accommodate the storage changes within Exchange Server 2013, however the planning, configuration and results interpretation process remain largely the same as they were in Jetstress 2010.
Change overview in Jetstress 2013
The Event log is captured and logged to the test log. These events show up in the Jetstress UI as the test is progressing.
Any errors are logged against the volume that they occurred. The final report shows the error counts per volume in a new sub-section.
A single IO error anywhere will fail the test.
In case of CRC errors (JET -1021), Jetstress will simulate the same behaviour as Exchange “page patching”.
