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 37) where the following protocols are supported:
l "CIFS Protocol" on page 37
l "NFS Protocol" on page 38
Figure 5: NAS Backup using CIFS 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.
2.8.3 CIFS Protocol
The CIFS (Common Internet File System) protocol defines a standard for remote file access
from many computers at a time in Windows environments.
