Features | HP Enterprise File Services WAN Accelerator specification

As shown in Figure 1-1the HP EFS RCU can be used to transparently prepopulate data from the server at the data center, to the HP EFS WAN Accelerator at the remote site. Thus, when clients at the remote site access data, they can observe LAN-like performance.

Features

With the HP EFS RCU running on the client and server, you can perform the following actions:

Data Transfer. The HP EFS RCU efficiently transfers data from a client to a specified target directory on a server across the WAN. The HP EFS RCU eliminates extra round-trips caused by Common Internet File System (CIFS), reducing that amount of time it takes to transfer data across the WAN.

Mirroring. The HP EFS RCU synchronizes a directory on the server with one on the client. Mirroring applies to files changed, added, and deleted on the client.

Monitoring. The HP EFS RCU can actively monitor client directories and perform a variety of actions such as mirroring or copying data, when it detects a change in them.
