HP Enterprise File Services WAN Accelerator manual PFS Operating Modes

PFS Operating Modes

Proxy File Service	Description
Term
Domain Controller (DC)	Specifies the domain controller name, the host that provides
	user login service in the domain. (Typically, with Windows 2000
	Active Directory Service domains, given a domain name, the
	system automatically retrieves the domain controller name.)
Share	The data volume exported from the origin server to the remote
	HP EFS WAN Accelerator.
Local Name	The name that you assign to a share on the HP EFS WAN
	Accelerator, this is the name by which users identify and map a
	share.
Remote Path	The path to the data on the origin server or the Universal
	Naming Convention (UNC) path of a share to which you want
	to make available to PFS.
RCU Server	The name of the Windows server where the HP EFS Remote
	Copy Utility (HP EFS RCU) is running. The RCU server may
	be the same as the origin server.
Share Synchronization	Synchronization runs periodically in the background, ensuring
	that the data on the proxy file server is synchronized with the
	origin server. You have the HP EFS WAN Accelerator refresh
	the data automatically by setting the frequency, in seconds; or
	manually at anytime.

Each individual file share on the HP EFS WAN Accelerator is configured in one of the following operating modes:

‹Broadcast Mode. Provides branch-office HP EFS WAN Accelerators with local read-only copies of data stored on the origin server. CIFS clients who map a Broadcast mode file share on the HP EFS WAN Accelerator cannot make changes to the files in that file share. The data is updated periodically on the HP EFS WAN Accelerator with the data from the origin server. You specify the frequency of updates (synchronization) when you configure a share.

‹Local Mode. Provides read-write access to a given file share hosted on the branch-office HP EFS WAN Accelerator. CIFS clients mapping a Local mode file share have read-write access to that share. Changes made to the share are sent back to the origin server. For any remote path, there can exist only one local share on any HP EFS WAN Accelerator, this prevents conflicting data from being written to the same path.

NOTE: In Local Mode, the HP EFS WAN Accelerator copy of the data is the master copy, do not make changes to the shared files on the origin server directory while in Local mode. Changes are propagated from the HP EFS WAN Accelerator to the origin server.
