About CIFS prepopulation
CIFS prepopulation settings are under Optimization > Protocols CIFS Prepopulation.
This feature enables SteelHead to perform an initial read of the data on the prepopulation share. The appliance’s primary interface acts as a client and prerequests data from the share you want to use to warm the data store. This request goes through the LAN interface to the WAN interface out to the server-side appliance, causing the in-path interface to see the data as a normal client request.
When data is requested again by a client on the local LAN, the appliance employs SDR and sends only references and new or modified data over the WAN, dramatically increasing the rate of data transfers. The first synchronization, or the initial copy, retrieves data from the origin file server and copies it to the appliance data store. Subsequent synchronizations happen at intervals.
The AWS Cloud Accelerator supports CIFS Prepopulation only with WCCP or PBR.
Enable CIFS Prepopulation prewarms the data store. Disabled by default.
Enable transparent prepopulation support using RCU opens port 8777 to allow manual data store warming using the Riverbed copy utility (RCU).
