Transparent Prepopulation. With transparent prepopulation the HP EFS RCU warms the data store of deployed HP EFS WAN Accelerators with data from the client. When a data store is warm, the HP EFS WAN Accelerator has already seen the data. When data is sent again over the WAN only new or modified data is sent, dramatically increasing the rate of data transfer over the WAN.

Static Backup. With the HP EFS RCU, when a scheduled static backup window occurs, because the data is already prepopulated in the HP EFS WAN Accelerators (using the transparent prepopulation feature), only new and modified data is transported to the backup site. Static backup allows enterprise customers to reduce their backup windows.
Proxy File Service (PFS). The HP EFS RCU can be run in concert with PFS, an optional feature on the HP EFS WAN Accelerator. PFS provides LAN access to files originating across the WAN and continuous access to files in the event of WAN disruption. PFS allows you to store local copies of files at the remote site in an integrated virtual file server resident on the HP EFS WAN Accelerator. For more information on PFS see, the HP StorageWorks Enterprise Files Services WAN Accelerator Deployment Guide.
