Implementing HA storage cluster - Open-E DSS V7 Active-Active Load Balancing iSCSI HA SAN cluster

The setup that I used for this implementation is mentioned below :

-Two DELL PowerEdge R710 servers (ESXI01 and ESXI02)

-Implemented Open-E DSS V7 Active-Active iSCSI HA SAN Cluster – using two VSA’s running on different ESXI 5.5 hosts

-In Active-Active mode, both nodes of the cluster will simultaneously run volumes providing high availability of data

-Overall cluster performance will be improved compared to Active-Passive mode since the read, write and replication traffic can be balanced on both nodes

-Open-E cluster nodes :

• Node A1 on ESXI01 
• Node B1 on ESXI02 
• Configured separate network interfaces for heartbeat, volume replication and WEB GUI management
• Added direct point-to-point connection between the above two ESX hosts for reliable volume replication
• Configured iSCSI volumes and targets on Node A1 and Node B1
• Configured replication tasks and failover cluster with multiple auxiliary paths
• Configured virtual target IP address and added targets to cluster
• Started cluster

Note :

Detailed configuration guide is given in Open-E website itself
