2.8.2 Network Attached Storage (NAS)
The ETERNUS CS800 system has the ability to serve as a NAS backup system (see "Network
Attached Storage (NAS)" on page 34) where the following protocols are supported:
l "CIFS/SMB Protocol" on page 34
l "NFS Protocol" on page 35
l "Application Specific Protocol" on page 35
Figure 5: NAS Backup using CIFS/SMB and NFS
NAS shares are optimized for backup (i.e. typically large files) rather than file
sharing. When used with many small files, the performance may be degraded.
2.8.2.1 CIFS/SMB Protocol
The CIFS/SMB (Common Internet File System) protocol defines a standard for remote file
access from many computers at a time in Windows environments.
