Setting up BranchCache

You can use System Manager to configure BranchCache on a CIFS-enabled storage virtual machine (SVM) to enable caching of content on computers local to requesting clients.

1. Click the SVMs tab.
2. Select the SVM, and then click Manage.
3. Click the SVM Settings tab.
4. In the BranchCache tab, click Set Up.
5. In the BranchCache Setup dialog box, enter the following information:
   1. Specify the path to the hash store.
      The path can be to an existing directory where you want the hash data to be stored. The destination path must be read-writable. Read-only paths, such as Snapshot directories, are not allowed.
   2. Specify the maximum size (in KB, MB, GB, TB, or PB) for a hash data store.
      If the hash data exceeds this value, older hashes are deleted to provide space for newer hashes. The default size for the hash store is 1 GB.
   3. Specify the operating mode for the BranchCache configuration.
      The default operating mode is set to all shares.
   4. Specify a server key to prevent clients from impersonating the BranchCache server.
      You can set the server key to a specific value so that if multiple servers are providing BranchCache data for the same files, clients can use hashes from any server using that same server key. If the server key contains any spaces, you must enclose the server key in quotation marks.
   5. Select the required BranchCache version.
      By default, all the versions supported by the client are selected.
6. Click Set Up.
