5. Select Broadcast, Local, or StandAlone from the Mode drop-down list.
6. Type the remote path for the share in the Remote Path text box.
TIP: You specify the remote path using the Uniform Naming Convention (UNC) for the
mapped drive. For example, \\<origin-file-server>\<local-name>.
7. Type the server name and port in the Server Name and Port text boxes.
8. Type frequency of updates (synchronization) in seconds, in the Synch Frequency
text box.
9. Optionally, type a comment that describes the share in the Comment text box.
10. Click Add Share to add the share to the Shares list.
Mode Description
Broadcast In Broadcast mode, the share originates on the origin server and a read-
only copy is available as a share on the branch office HP EFS WAN
Accelerator. 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 In Local mode, after the HP EFS WAN Accelerator receives the initial
copy, new data generated by clients is periodically synchronized to the
origin server. The folder on the origin server essentially becomes a
back-up folder of the share on the HP EFS WAN Accelerator and it has
read-only permissions; as such, users cannot directly write to this
folder.
Check the permissions of the folder on the origin server where the
share will be synchronized to and make sure that domain users have
read and write permissions.
For Local mode, make sure that the target directory on the origin server
is either not shared or is only shared as a read-only folder.
TIP: Change the permissions of the folder on the origin server to read-
only for all domain users except the domain administrator. The domain
administrator must have write permissions because the RCU uses that
to update this folder. This change must be propagated to all files and
subdirectories in this directory. (This prevents any other user from
writing to this directory.)
CAUTION: In Local Mode, the HP EFS WAN Accelerator copy of
the data is the master copy, do not make changes to the shared files
from the origin server while in Local mode. Changes are propagated
from the remote office hosting the share to the origin server.
StandAlone Provides read-write access to data on a branch office HP EFS WAN
Accelerator. There may or may not be an origin server at the data
center with which the share has to synchronize data to. For example, if
you want to load temporary data that does not need to be backed up at a
data center, you can create a share in Stand-Alone mode with or
without a remote path.
