Does DataMiner currently support SMSEagle hardware redundancy ? In case it is supported and 2 pcs SMSEagle are connected to the DMS, that would mean 2 SIM cards and 2 different mobile numbers. Will both be active at the same time (active/active or active/standby) ?
Hi Didier,
There are two types of redundancy that you can do with a SMSEagle gateway. Modem redundancy with a dual SIM device or hardware redundancy with two devices using the HA cluster feature.
With a dual SIM device and installing two SIMs cards, you can have a modem redundancy and also a network operator redundancy (if SIMs are from different operators). Also, you can increase the sending/receiving throughput of up to 60 SMS/min.
With the HA cluster feature, you can run two SMSEagle devices very close to how DMA FA works. It uses a virtual IP and the Virtual Router Redundancy Protocol. I didn't test this configuration but from the point of view of DataMiner is just one IP therefore one device, so it should be transparent.
There is more information about high availability cluster in this link

Hi Didier,
This is currently not supported.
Thanks Fernando !
