Introduction to Storage Networking
Storage Networking Applications
• Backup applications:
– LAN-free and serverless backup
– Remote backup
– Snapshots and split mirrors
– Synchronous mirroring
• Key benefits of SAN:
– Reduced backup and restore times
– Remote connectivity
– Continuous operation
SANs can provide substantially increased performance for backup and
In a 24x7 operation, there is no good time to take systems down for
backup or maintenance.
Continuous operation requires fault-tolerance, rather than recovery.
Disaster-tolerance requires complete, current, and accurate copies of
data in widely dispersed locations.
