4. Shut down or restart the system.

Appendix A. Gateway Protocol Support

This appendix provides information that may be useful to the CFS Protocol Gateway server

administrator or implementer.

Protocol Gateway Limitations

The CFS Protocol Gateway administrator or implementer should note the Dell DX Object Storage cluster

provides support for a metadata-rich set of attributes that may be used to describe binary objects that

are being stored. The use of file sharing protocols limits how these may be used since attributes that

are not known to the underlying network file system topography cannot be utilized.

Supported Protocols

CFS can be used with any file sharing technology however, Dell‘s development efforts to date have

focused primarily on SMB/CIFS and NFS. The focus of this deployment guide is upon specific support for

SMB/CIFS and NFS.

Access Control Lists

POSIX ACL (Access Control List) metadata will be mapped into the Dell DX Object Storage HTTP SCSP

metadata header content only if the underlying file system has been mounted with POSIX compliant

ACL support and with Extended Attributes (EAs) enabled.

Where the CFS protocol gateway is used to access the Dell DX Object Storage via the SMB/CIFS

protocols, Microsoft Windows NTFS and NTFS5 ACLs will be mapped to the nearest equivalent POSIX

ACLs, but this will be possible only where the underlying file system has been mounted with support for

POSIX ACLs and Extended Attributes.

It should be noted the mapping of MS Windows NTFS ACLs will be affected not only by a closely

approximated mapping to POSIX ACLs, but additionally may be overridden by specific share

specification parameters that can be used to enforce access controls in such manner that even the MS

Windows network administrator cannot change or override them. Description of such controls is beyond

the scope of this document.
