1:1 Configuration
RC sync, async streaming and periodic
P S
3PAR Remote Copy Asynchronous Streaming
Continuous operation with RPO close to 0
• Efficient with higher latency links
• Local write acknowledgement • Maintains local server write IO performance and latency • Write IO data is queued in local cache and replicated at max available link speed

3DC Peer Persistence Solution
• Combines the metro-distance synchronous Peer Persistence HA solution (RTO=0) with continental distance asynchronous Remote Copies for Disaster Tolerance (DT) New with 3PAR OS 3.3.1
Create new Source Volume
New Target Volume created autonomically
Autonomic Remote Copy Volume Group
•
Volumes grouped together to maintain write ordering across sets of volumes Useful for databases or other applications with dependencies Secondary groups and volumes are autonomically created and credentials inherited
