PFS Operating
Modes
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.
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.
