80 2 - C ONFIGURING THE HP EFS WAN A CCELERATOR
PFS requires an HP EFS WAN Accelerator, Model DL320-1010, DL320-2010,
DL320-1020, DL320-2020, DL380-3010, or DL380-5010 to ensure adequate disk
capacity. PFS supports only Windows 2000 and above domains.
NOTE: The Setup: Proxy File Service - Configuration page only appears if you are running a
HP EFS WAN Accelerator, Model
DL320-1010, DL320-2010, DL320-1020, DL320-
2020, DL380-3010, or DL380-5010 . These models have the necessary disk capacity to
perform PFS.
Enabling PFS
Optionally, you can enable PFS support if you have a HP EFS WAN Accelerator,
Model DL320-1010, DL320-2010, DL320-1020, DL320-2020, DL380-3010, or
DL380-5010 in the Setup: Proxy File Service- Configuration page. PFS supports only
Windows 2000 and above domains.
PFS is an optional integrated virtual file server that allows you to store copies of files
on the HP EFS WAN Accelerator with Windows file access, creating several options
for transmitting data between remote offices and centralized locations with improved
performance and functions. Data is configured into file shares by PFS; and the shares
are periodically synchronized (updated) transparently in the background, over the
optimized connection of the HP EFS WAN Accelerator. PFS leverages the integrated
disk capacity of the HP EFS WAN Accelerator to store file-based data in a format that
allows it to be retrieved by Network Attached Storage (NAS) clients.
PFS runs in concert with the HP EFS Remote Copy Utility (RCU). The RCU must be
installed on the origin server or on a separate Windows host with write-access to the
data utilized by PFS. For detailed information, see the HP StorageWorks Enterprise
File Services Remote Copy Utility Reference Manual.
PFS provides:
‹ LAN access to data residing across the WAN. File access performance is
improved between central and remote locations. PFS creates an integrated file-
server periodically updated transparently, at intervals specified by the
administrative user, with data from the origin file server. This provides access to
the data from across the LAN as opposed to the WAN, drastically improving
speed and performance.
‹ Continuous access to files in the event of WAN disruption. PFS provides
support for disconnected operations. In the event of a network disruption that
prevents access over the WAN to the origin server, files can still be accessed on
the local HP EFS WAN Accelerator.
‹ Simplify Branch Infrastructure and Backup Architectures. PFS consolidates
file servers and local tape backup from the branch into the data center. PFS
running in concert with the RCU, enables a reduction in number and size of
backup windows running in complex backup architectures.
