WinPE Peer Cache RRS feed

  • Question

  • Experts,

    Could you please give me an insight of WinPE Peer Cache?

    If we plan to make use of WinPE Peer Cache on a remote branch office, Will the scope limited to the same subnet ?

    Or clients from all subnets from that remote branch office can make use of the peer cache source and get the content from cache during a Wipe/Load task sequence. We are in the planning phase of upgrading Windows 7 machines in the remote offices to Windows 10 and trying to see if peer cache could help us.

    Cheers !

  • Its just called peer cache. Clients in WinPE or full OS can get content from other clients.

    The scope is not limited to clients on the same subnet. Instead, the scope is based on your boundary definitions.

  • Thanks Kevin.

    I got confused after seeing the technet documentation.

    https://docs.microsoft.com/en-us/sccm/osd/get-started/prepare-windows-pe-peer-cache-to-reduce-wan-traffic

    Consider a scenario with a branch office that does not have a distribution point but does have several clients enabled to use Windows PE Peer Cache. You deploy the task sequence configured to use peer cache to several clients that are configured to be part of the peer cache source. The first client to run the task sequence broadcasts a request for a peer with the content. It doesn't find one so it gets the content from a distribution point across the WAN. The client installs the new image and then stores the content in its Configuration Manager client cache so it can function as a peer cache source to other clients. When the next client runs the task sequence, it broadcasts a request on the subnet for a peer cache source, and that first client responds and makes its cached content available.

    In the above details provided by Microsoft, This works through a broadcast on the subnet.  Could you please clarify?

    Cheers !
