HPE 3PAR Persistent Ports is a feature that enables a non-disruptive environment by allowing host-based multi-pathing software to remain unaffected during events such as firmware upgrades. With Persistent Ports, the active I/O paths are automatically moved to alternate ports if the primary ports are undergoing maintenance or upgrades, ensuring continuous data access and eliminating disruptions.
