Question
A systems administrator asks whether non-disruptive migration (NDM) is supported between their VMAX All Flash arrays. The arrays are located 800 km apart.
What information should be provided to the administrator?
A. NDM is only supported if the source array is running HYPERMAX OS 5977
B. NDM is supported between the arrays
C. NDM is not supported between the arrays
D. NDM is only supported if the target array is running PowerMax OS 5978
Answer
C. NDM is not supported between the arrays
Explanation
Non-disruptive migration (NDM) is not supported between VMAX All Flash arrays that are located 800 km apart. The maximum distance supported for NDM is 200 km. Beyond this distance, factors such as latency and signal degradation can impact the reliability and performance of the migration process. Therefore, in this scenario, where the arrays are separated by 800 km, NDM cannot be used, and alternative migration methods should be considered.
