HP Enterprise File Services WAN Accelerator manual Control Description

	4. Use the controls to complete the configuration, as described in the following table.
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.)
Default Volume		Enable Default Volume with Policy. Specify this option and select one of the following
		options from the drop-down list to configure the default policy for NFS volumes:
		• Global Read-Write. Specifies a policy that provides a trade-off of performance for

		NFS clients (which do not go through the HP EFS WAN Accelerators) and clients
