5. Use the controls to modify the configuration, as described in the following table.
Control Description
Comment Optionally, specify a comment to help you identify the share.
Mode Select one of the following options from the drop-down list:
• Broadcast. 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 when and how frequently updates (that is, synchronization) are to occur
when you configure a share.
IMPORTANT: For Broadcast mode: if you are performing directory moves regularly
(for example, mv ./dir1/dir2 ./dir3/dir2), incremental synchronization will not reflect
these directory changes. You must perform a full synchronization more frequently to
keep the PFS shares in synchronization with the remote site.
IMPORTANT: While performing a incremental synchronization for Broadcast mode
share, if files are deleted on the server, they are not deleted on the HP EFS WAN
Accelerator.
• Local. 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. Users must not directly write to this folder on the origin server. You
specify when and how frequently updates (that is, synchronization) are to occur when
you configure a share.
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.
NOTE: PFS does not support non-domain accounts other than Administrator accounts.
If you create Local mode shares on a non-administrator account, your security
permissions for the share will not be preserved on the origin server.
• Stand-Alone. Provides the branch-office HP EFS WAN Accelerator with a one time
working copy of data mapped from the origin server. You can specify a remote path to
a directory on the origin server, creating a copy at the branch-office. This data is not
synchronized back to the origin server. The stand-alone share is an initial and one-time
only synchronization.
Version 2 Port. Specify the port for the server.
Version 3 Account. Specify the fully qualified Windows login (including domain) to be used to
access the shares folder on the origin file server. For example,
<Domain>\Administrator.
IMPORTANT: Make sure the users are members of the Administrators group on the
remote share server, either locally on the file server (the local Administrators group) or
globally in the domain (the Domain Administrator group).
Password/Password Confirm. Specify and confirm the password to be used to access
the shares folder on the origin file server.
Incremental Sync Schedule, Date
and Time Specify the date and time that you want updates (synchronization) to start. The first
synchronization, or the initial copy, retrieves data from origin file server and copies it to
the local disk on the HP EFS WAN Accelerator. Subsequent synchronizations are based
on the synchronization interval.
IMPORTANT: For Local mode, changes are synchronized from the HP EFS WAN
Accelerator to the origin file server; Broadcast mode changes are synchronized from
the origin file server to the HP EFS WAN Accelerator.
