Explanation
Persistent Ports This is a really cool feature as well - it gives the ability to provide redundant connectivity to multiple controllerson a 3PAR array without having to have host-based multipathing software.How is this possible? Basically it isNPIV for the array. Peer controllers can assume the world wide names for the ports on their partner controller. If a controller goes down, it's peer assumes the identities of that controller's ports, instantaneously providingconnectivity for hosts that were (not directly) connected to the ports on the downed controller. This eliminatespauses for MPIO software to detect faults and fail over, and generally makes life a better place.
