HP Enterprise File Services WAN Accelerator manual PFS Terms, Proxy File Service Description Term

PFS runs in concert with the HP EFS Remote Copy Utility (HP EFS RCU). The HP EFS 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 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, enabling clients to access data directly from the PFS on the LAN as opposed to the WAN. Transparently in the background, data on the PFS is synchronized with data from the origin file server over the WAN.

‹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 enables a reduction in number and size of backup windows running in complex backup architectures.
