Prepositioning is done to prime the CIFS cache on the remote WAE.Priming the CIFS cache allows the first user of a file to experience the same performance level as subsequent users normally get.
1)From the Dashboard go to Configure->File Services->Preposition and click the “Create” icon.
2) Enter the name for the preposition rule, file server name, and the Active Directory credentials the WAEs should use to retrieve the data.This AD username/password is only used by the WAEs for gathering prepositioned data.Enter the directories to preposition.If the AD credentials are correct you can click the Browse button to select the directories.
3) Go to the Assign Edge Devices tab and assign the appropriate devices to preposition the data to.
4) Go to the Schedule tab to schedule the preposition job.The screen shot below shows a job configured to run at midnight daily.Once finished click Submit.
5) Use the Preposition Status tab to monitor the status of the preposition job.
Can a new WAE pull prepositioning CIFS Cache from another WAE that has been in place for several months?
I have a new WAE 674 being stood up in 1 week, I have several WAE 512s in other branches today. How would I pull the content off a current WAE 512 to a File Server and tell the new WAE 674 to retrieve that content?
WAAS can only preposition content directly from an origin server. There is no tiered preposition capability.
The cached content on the 512s you have today is a copy of content on an orgin server. You would configure the 674 to preposition the content from that origin server directly. If it's possible to bring the 674 up at the same location at the origin server before you deploy it, the initial preposition could be done over the LAN for improved performance.
