6. Local replication – Volume copy/mirror
Production Server
• Volume Copy
Immediately usable (Read/Write)
point-in-time (PIT) full data
copies within a single system
Uses
- Support secondary tape
applications such as analysis, Target
backup
testing and backup
Source Target
Benefits Target
- Minimize performance
degradation and data
corruption risk of production decision
volume support
application testing

7. Local replication – Volume copy/mirror
Production Server
• Volume Mirror
Sync or async full data copies
within a single system
Uses
- Restart services within
minutes after source volume tape
fatal failure Target
backup
Source Target
Benefits
- Highest data availability Target
users can achieve in single-
system configuration
decision
support
application testing

8. Remote replication
• Sync or async full data copies across • Uses
systems Restart services in minutes after
Via FC or iSCSI host ports disaster
Support remote snapshot Centralize backup data
- Used with async mode, take Achieve continuous data
snapshot whenever protection while offloading source
synchronization session ends system

9. Thin Provisioning
Capacity is dynamically allocated when
data blocks are written
Cost benefits
Delay equipment acquisition
Optimize capacity utilization: 30-
40% 80-90%
Reduce power, space and cooling
expenses
Management benefits
Expand volume without downtime
Simplify capacity planning
Eliminate individual volume
utilization monitoring efforts
