A customer has systems with AIX 6.1 and 5.3 distributed across two data centers located 8km apart. They want to implement high availability with automated application restart and synchronous data replication between the IBM Systems Storage DS8700 systems which are installed in each datacenter. Which solution addresses the customer requirements？（）

• A、Use the Geographic Logical Volume Manager （GLVM） for MetroMirror， and Live Partition Mobility to automate partition migration upon failure
• B、Use MetroMirror for the AIX volumes and High Availability Disaster Recovery （HADR） to automate partition migration and restart upon failure.
• C、Use the Geographic Logical Volume Manager （GLVM） for MetroMirror to replicate the data between the two sites and automate application recovery.
• D、Use MetroMirror for the AIX volumes， and PowerHA SystemMirror Enterprise Edition to automate failover of MetroMirror pairs and automate application recovery.
