Single controller mode can be upgraded to dual controller mode please contact the distributor for upgradable In addition ISNS server is recommended It s important for keeping I O running smoothly when RG ownership is switching or single controller is failed Without ISNS server when controller 1 fails the running I O from host to controller 1 may fail because the time which host switches to the new portal is slower than I O time out With ISNS server this case would not happen 111 5 11 Replication Replication function will help users to replicate data easily through LAN or WAN from one IP SAN storage to another The procedures of Replication are on the following 1 Copy all data from source VD to target VD at the beginning full copy 2 Use Snapshot technology to perform the incremental copy afterwards Please be fully aware that the incremental copy needs to use snapshot to compare the data difference Therefore the enough snapshot space for VD clone is very important e Setup the Replication port on the source IP SAN storage The Replication uses the last iSCSI port on the controller to replicate the data When the ISCSI is configured as Replication port it is no longer available for the host to connected as iSCSI port until it is configured as the normal iSCSI port again 1 In the operation menu of the last iSCSI port on the controller select Enable Repication to set this port as the Replication port The last
