Control Description
Server Settings Server Policy. Select one of the following options from the drop-down list to configure
the default policy for NFS servers:
• Global Read-Write. Specifies a policy that provides a trade-off of performance for
data consistency. All of the data can be accessed from any client, including LAN based
NFS clients (which do not go through the HP EFS WAN Accelerators) and clients
using other file protocols like CIFS. This option severely restricts the optimizations
that can be applied without introducing consistency problems. This is the default
configuration.
• Custom. Enables you to turn on or off the root squash feature for NFS volumes from
this server.
• Home Directory. All accesses to each directory are by a single user. This policy allows
aggressive caching of data and metadata.
Apply. Click Apply to apply your settings to the running configuration. (Apply your
settings to test a new configuration before saving them permanently.)
