Description

 Flashcopy-based (vs. store-and-forward) async mirroring

 Periodic/automatic resynchronization from primary to

secondary (continuous, periodic, or manual)

 Stable/consistent image always preserved on secondary

volume (via PiTs)

 Mirroring over Fibre Channel and iSCSI

Benefits

 Simplify Storage and Data Management

o FlashCopy recovery point on disk reduces further protection

required for secondary copy (i.e., tape)

 Improve Data Protection and Data Integrity

o Rollback to secondary FlashCopy to recover from interrupted or

incomplete resynchronization

 Improve Performance

o Primary volume IO performance not impacted by link speed or

latency (no write-order consistency impact)

Enhanced Global Mirroring

Improved Protection against Local and Wide-Area Disasters
