NFS Cache storage query

[Sanjeev Neelarapu]

Hi,

I have a query on how to add NFS Cache storage.
Before creating a zone if we create a secondary storage with s3 as the storage 
provider and don't select NFS Cache Storage then we treat it as S3 at region 
level.
Later I create a zone and at "add secondary storage" creation wizard in UI if I 
select NFS as secondary storage provider will it be treated as NFS Cache 
Storage? If not is there a way to add NFS cache storage for that zone?

Thanks,
Sanjeev
