- You have a Windows Server 2012 failover cluster that is configured by using continuously available file shares.
- An I/O stress test is running on a Windows 8 or Windows Server 2012-based client against the failover cluster. The stress test has a high ratio of open and close operations to data operations. For example, the test repeatedly opens a file on the file share, reads the file, and then closes the file.
Note This scenario may be found in stress tests but does not map directly to customer-usage scenarios.
