PFS requires an HP EFS WAN Accelerator DL320-1010, DL320-2010,

DL380- 3010, or DL380-5010 to ensure adequate disk capacity. PFS supports

only Windows 2000 and above domains.

Introduction to PFS

PFS is an optional feature that allows you to store local copies of files at a

remote site in an integrated virtual file server resident on 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 provides:

 Fast local access to files in mapped directories. LAN performance to files

residing across the WAN. File access performance is improved between

central and remote locations. File access performance is improved for

applications that access large numbers of very small files.
