No. Never do this.
Namespaces using NFS, CIFS or WebDAV should NOT use S10, S30, S11, S31 or public cloud. We require service plans that are wholly backed by G10 nodes or SAN.
If there isn’t enough capacity in the G-nodes or SAN, then you might take a closer look at HCP Anywhere edge. Edge provides NAS gateway functions, using HCP on the backend, and can use any backend storage, including S-nodes and public cloud.
