We conducted the validation tests to determine how S-1 works with Unity XT storage arrays.
The test results shown in the following table are based on a conservative model to ensure that the constant-bandwidth video traffic is unaffected during a single storage processor (SP) maintenance cycle, disk rebuild, or similar performance-intensive events.
