� N_Port ID Virtualization or NPIV allows multiple Fibre Channel initiators to occupy a single physical port.
� NPIV virtual adapter definitions & PowerHA work just like an environment using dedicated adapters
� The NPIV functionality presents an attractive offering for customers trying to circumvent under utilized resources. In one way standby configurations the

circumvent under utilized resources. In one way standby configurations the fallover server would not need a dedicated HBA
� NPIV allows you to run an environment with dedicated HBAs on the prod side and virtual on the target machine, or both virtual emulating a direct attached environment

WebSMIT
� Observe status of all your clusters– Get the status of a cluster– Get the status of a node within a cluster– Generate reports on any cluster as desired
� Manage a cluster Make configuration changes
– Add, remove, edit, create HACMP configuration� Install WebSMIT on one system
– No footprint of WebSMIT on managed nodes– No performance impact on managed clusters
© 2009 IBM Corporation20
– No performance impact on managed clusters– Single sign-on for all of your WebSMIT managed
clusters � Security management
– Implement WebSMIT on a system outside of the managed clusters
– Same communication daemon as used by HACMP (clcomd) with the same encryption technology
– Access control for all of your WebSmit users– Enable administrators with read only access
