Shares are filesystems and LUNs that are exported over supported data protocols to clients of
the ZFSSA. Filesystems export a file-based hierarchy and can be accessed over SMB, NFS, HTTP/WebDav, and FTP. LUNs export block-based volumes and can be
accessed over iSCSI or
Fibre Channel. The project/share tuple is a unique identifier for a share
within a pool. Multiple projects can contain shares with the same name, but a single project cannot
contain shares with the same name. A single project can contain both filesystems and LUNs, and they
share the same namespace.
