How Does PFS Work?
PFS provides Windows file service in the HP EFS WAN Accelerator at a
remote site or branch office. The HP EFS WAN Accelerator is configured as a
Domain Member Server. Data volumes at the data center are configured
explicitly on the proxy-file server and are served locally by the HP EFS WAN
Accelerator. As part of the configuration, the data volume including the
Access Control Lists (ACLs) from the origin server are copied on to the HP EFS
WAN Accelerator.
PFS in the HP EFS WAN Accelerator allows a Domain Controller (DC) to
authenticate users accessing its file shares. The DC can be located at the remote
site or over the WAN at the main data center. The HP EFS WAN Accelerator
must be configured as a Member Server in the Windows 2000, or later, Active
Directory Services (ADS). Domain users are allowed to access the PFS shares
based on the access permission settings provided for each user.
Security Signature Specifies the definition for Windows SMB signing on your
client machine. Enabling PFS restricts SMB signing:
• Disabled. This is the default value. If the client has
security signatures set to required, PFS will not function.
This setting assumes that clients are not using security
signatures.
• Enabled. If the client has security signatures set to
enabled, PFS is supported. If not, PFS continues to
function in any case.
• Required. PFS only functions if the client has security
signatures set to enabled. If they do not, PFS will not
function.
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.
Remote Path The path to the data on the origin server or the Universal
Naming Convention (UNC) path of a directory to which
you want to copy and synchronize data to.
Share Server The name of the Windows server where the HP EFS
Remote Copy Utility (HP EFS RCU) is running.
Share Synchronization Synchronization runs periodically in the background,
ensuring that the data on the proxy-file server is
synchronized with the origin server. You set the
frequency, in seconds, by which the HP EFS WAN
Accelerator refreshes data.
