Branchcache over ONTAP CIFS

lucabisceglia — Wed, 04 Jun 2025 09:52:21 GMT

Hi,

I have a customer with over 200 branches each with a Windows server. They wish to implement a central caching solution. We evaluate the Global File Cache solution but it's very expensive for the licensing model.

I heard about Branchcache and I'm wondering if this could be a good solution. We only need to have a central FAS and then caching the shares across the branches.

Did you have some experiences so far ? Many thanks Luca

Considering your scenario, I think Microsoft BranchCache can do the job for you. Sorry, I don't have practical experience of using it but from whatever I have read, it does the job, especially for your case-requirement (200 branches etc).

Use BranchCache to cache SMB share content at a branch office overview:

BranchCache supported versions of ONTAP:

Configure BranchCache:

Another option: NetApp FlexCache (Not suitable for your requirement)
FlexCache is supported on AFF, FAS, and ONTAP Select systems running ONTAP 9.5 or later versions. A cache is a temporary storage location that resides between a host and a source of data. The objective of a cache is to store frequently accessed portions of source data in a way that allows the data to be served faster than it would be by fetching the data from the source. FlexCache in ONTAP solves these problems by providing a writable, persistent cache of a volume in a remote place that is consistent, coherent, and current.
