HP Enterprise File Services WAN Accelerator manual When to Use PFS, 1. PFS Deployment

When to Use

PFS

The proxy file server can export data volumes in local mode, broadcast mode, and stand-alone mode. 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.

Figure 8-1.PFS Deployment

PFS can be configured with any number of file shares in different modes. Shares are configured into different operating modes based on the use of your data:

‹For environments seeking to broadcast a set of read-only files to many users at different sites. Broadcast Mode quickly transmits a read-only copy of the files from the origin server to your remote offices.

‹For environments that need to efficiently and transparently copy data created at a remote site to a central data center, perhaps where tape archival resources are available to backup the data. Local Mode enables read-write access at remote offices to update files on the origin file server.

‹For network environments where it is more effective to maintain a separate copy of files that are accessed locally by the clients at the remote site. In Stand-Alone Mode, create a proxy file server at a remote office using the remote office HP EFS WAN Accelerator, creating extra storage space.

If any of the above advantages can benefit your environment, then enabling PFS in the HP EFS WAN Accelerator is appropriate.
