Jetstress Test Result: SV110
The purpose of this test is to verify the storage configuration which the customer is planning to deploy. The test run has been successful, meaning the database read latency and log write latency are below 20ms; Database page fault stalls/sec is 0. However, Microsoft strongly recommends that you perform further validation of this storage solution (additional tasks listed below):- 1.You should refer to the table below to determine if the actual
disk IO (achieved IO) has exceeded the targeted IO (expected IO). If not,
you may want to increase the thread count to increase the load, provided
that the disk latency will not exceed the threshold.
- 2.You need
to confirm whether the storage solution has synchronous replication as
part of the implementation. If the solution does not utilize synchronous
replication, then you should check für the database write latency, the
desired value should be under 20 ms. (Please refer to http://support.Microsoft.com/?kbid=895847 für synchronous replication definitions.)
- 3.Please check the
status pane in the Jetstress window, to make sure that no errors were
logged during the database checksum validation.
