EPLOYMENTS

After the HP EFS WAN Accelerator receives the initial copy of the data and ACLs, the

shares can then be made available to local clients. The shares on the HP EFS WAN

Accelerator will periodically be synchronized with the origin server at specified

intervals, or manually by the system administrator. The HP EFS WAN Accelerator

uses Scalable Data Referencing (SDR) during the synchronization process which

optimizes the traffic across the WAN.

The HP EFS WAN Accelerator is configured as a Domain Member Server or a Local

Workgroup.

Figure 9-1. PFS Deployment

Domain Mode In Domain mode, you join the Windows domain for which the HP EFS WAN

Accelerator will be a member. Typically, this is the same domain as your company’s

domain. Use Domain mode if you want the HP EFS WAN Accelerator to be more

integrated in terms of permissions. Also, by joining the Windows domain you do not

have to manage local accounts (local workgroup mode) in the branch office.

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 ACLs from the origin server are copied on to the HP EFS

WAN Accelerator. PFS allocates a portion of the HP EFS WAN Accelerator data store

for users to access as a network file system.

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. Domain users are allowed to access the PFS shares based on the access

permission settings provided for each user.
