Heartbeat links and arbitration links between active-active arrays are physically isolated and cannot share the links.

Ports to be activated between the SVN and the EMM server
Ports to be activated between the SVN and the EMM server are 8080, 8081, and 8443. After ports are activated, run the telnet ip-emm server IP address port command on the SVN to check whether the communication is normal.

Do AR routers support dual SIM cards in being configured as active and backup links
AR routers support the dual SIM cards in being configured as the active and backup links that are connected to different LTE networks. The active SIM card is used for communications in general. If the RSSI of the main SIM card is lower than the threshold, the traffic switches over to the backup SIM card. When the RSSI of the active SIM card is higher than the threshold, the traffic switches over from the backup SIM card to the active SIM card.

Problem and solution when the active/standby switchover is not performed sometimes when the interface is faulty
Check the HRP priorities on both firewalls. When the interface of the active firewall is faulty, the priority is decreased by 2. If the decreased priority is still higher than or equal to the priority of the standby firewall, active/standby switchover does not occur.

Rival to the MacroSAN active-active solution
MacroSAN active-active solution realizes disaster recovery switchover at the application level by adopting the storage remote replication feature (synchronous/asynchronous), third-party arbitration, and multipathing software equipped in the host OS. Huawei’s active-active solution has the following countermeasures: 1. MacroSAN active-active solution is asymmetric, and the system works in active/standby mode. I/Os of the standby site are forwarded to the active site. In essence, the solution uses the volume mirror. The active-active solutions of other vendors and Huawei are symmetric. There is no active/standby site and I/O requests are processed at both sites. 2. MacroSAN active-active solution has distance limitation. In this solution, devices are mirrored by 10GE links. The high latency does not allow the distance between sites to be longer than 10 km. However, Huawei active-active solution allows the distance between two sites to be 100 km.
