What is the maximum number of active paths per director to a LUN?

The maximum number of active paths per director to a LUN in a VPLEX environment is four. This design allows for enhanced availability and load balancing across the multiple paths connecting hosts to storage resources. Using four active paths means that if one path experiences issues or fails, the other active paths can handle the traffic without interrupting service, which contributes to the overall resilience and performance of the storage solution. This is a fundamental aspect of VPLEX's architecture, as it leverages the ability to provide multiple paths to ensure that data remains accessible even in the event of hardware or configuration failures.

This capability also allows for effective resource utilization by balancing the input/output operations across the various active paths, thus optimizing performance.
