System performance changes
HP Scalable NAS provides a script called /etc/opt/hpcfs/SizingActions
that sets system parameters to provide good performance in a file serving environment.
By default, the script is integrated into the system startup and runs each time the
system is booted. For more information, see Adjust operating system
parameters, page 200.
Virtualized NFSD RPC reply cache
The virtualized NFSD RPC reply cache feature is enabled by default. This feature
provides a more transparent transition when a Virtual NFS Server fails over to another
