Data is written and read from Array 1
Data is periodically replicated to Array 2
In case of raid array error or disk drive error on the Raid Array 1, the server will send an e-mail notification to the administrator and/or users
The administrator then switches from Array 1 to Array 2
After switching, replicated data is available on Array 2
Data is written and read in System 1
Data is periodically replicated from System 1 to System 2 over the LAN
In case of raid array error, or disk drive error on System 1, the system will send an e-mail notification to the administrator
Administrator then switches users to System 2
After switching, replicated data is available on System 2
Data is written and read in System 1
Data is periodically replicated to System 2 via an Internet connection
In the event of a raid array error or disk drive error on System 1, the server will send an e-mail notification to the administrator, In the event of a loss of system 1 users will be notified,
Administrator then switches users to System 2 over the WAN.
After switching, replicated data is available on System 2

Synchronous Volume Replication with Failover over a LAN |
Volume Replication (synchronous) over LAN or WAN is block based and supports iSCSI, FC and NAS logical volumes. It provides data availability in case the source system is offline from a disaster and the destination will have the replicated data of the source server.
Volume Replication with Auto Failover is a fault tolerance process via iSCSI Volume Replication, that creates mirrored target data volumes.
Data is written and read to System 1
Data is continiously replicated to System 2
In case of raid array error or disk drive error on the System 1, the server will send an e-mail notification to the administrator, In the case of a failure of system 1, users will be notified,
Administrator then switches users to the System 2
After switching, replicated volume is available on System 2
Data is written and read to System 1
Data is replicated to System 2 via an Internet connection
In case of raid array error or disk drive error on the System 1, the server will send an e-mail notification to the administrator, In the case of a failure of system 1, users will be notified,
Administrator then switches users to the System 2 over the WAN.
After switching, replicated volume is available on System 2
Data is written and read to System 1 (primary)
Data is continually replicated to System 2 (secondary)
In case of raid array or disk drive error on System 1 (primary), the server will send an e-mail notification to the administrator. iSCSI Auto Failover determines there is no connection between the servers
After a few seconds Automatic Failover is executed and users are switched to System 2 (secondary)
After switching, the replicated volume is available on System 2 (secondary)
