Npv Mode Connectivity Guidelines; Npv With Flexattach; Npv Device With Dual Redundant Fabrics - HP StorageWorks 4000/6000/8000 - Enterprise Virtual Arrays Reference Manual

Failover between NP_Ports (uplinks) is supported.
Direct storage attachment is not supported, (requires at least one external Fibre Channel switch).
F_Ports, NP_Ports, and SD_Ports are supported.
NPIV-capable module servers (nested NPIV) are supported.
Local switching is not supported. All traffic is switched using the NPV core switch.
Remote SPAN is not supported.
NPV mode is managed separately from the BladeSystem; however, if used with C-series switches,
it uses a common SAN-OS.

NPV mode connectivity guidelines

NPV solutions are best suited for C-series-only fabrics in which you want multivendor switch
interoperability through NP_Ports instead of E_Ports.

NPV with FlexAttach

The Cisco MDS 9124e Fabric Switch for HP c-Class BladeSystem, MDS 9124 switch, and MDS 9134
switch support NPV with FlexAttach. FlexAttach provides automatic mapping of physical WWNs to
virtual WWNs using NAT. When NPV mode is enabled, FlexAttach allows SAN and server
administrators to install and replace servers without having to rezone or reconfigure the SAN.
