Async mirroring always uses FC verses IP for better performance.

Async mirroring can span long distances without performance loss.

Async mirroring was designed for server-to-server or disk-to-disk mirroring.

Based on the async mirroring standards, it is only good for distances in excess of 1000 (1600 km) miles.

multiView can take a PiT of the application that can be kept for recovery from disk and then backed up to tape during quieter processing times.

multiView can take a PiT of the application and then copy it over IP to another site for resilience.

multiView will take a full copy of the application which the backup application can then backup offline during less busy processing times.

A view of a PiT can be mounted on a backup server and backed up to tape with no data flow or processing overhead on the application server.

multiMirror will require FC-to-IP converters for better performance.

Snapshot-enabled mirroring requires less WAN bandwidth.

multiMirror eliminates the need to backup at all sites.

Repurposing existing storage will reduce the cost at the target site.

multiMirror will not corrupt data based on its internal ECC correction code.

Host-based mirroring uses IP which can be less reliable than FC.

multiMirror uses the reliability of the RAID devices to accomplish a much more reliable copy.

Snapshot-enabled mirroring allows multiMirror to retain several recovery points at the remote site for rollback purposes.
