HP 3PAR Persistent Ports
HP 3PAR Persistent Ports is another Tier 1 resiliency feature that provides non-disruptive online software upgrades on HP 3PAR StoreServ Storage without relying on multipathing software to initiate failover. This feature, available on all HP 3PAR StoreServ models, brings Tier 1 resiliency across the 3PAR StoreServ product line, including midrange models, by helping to ensure that host paths remain online throughout the software upgrade process.
The use of standard NPIV (N_Port ID Virtualization) technology enables a single host-facing 3PAR StoreServ port to assume the identity of additional predesignated partner ports, thus enabling transparent switchover of host path connections.
