Ordered 2x HEX as I saw they can run on those.
Only for small networks. Was not stable for us. Rb1100AHX4 is the device to run the Dude.
is not about stability, you must be aware of computational power of rb750gr3 cpu, its a little dual core like a cheap smartphone cpu you must size the dude accordingly:
maximum of 40 services monitoring and maximum 4 days of raw value data storage and maximum 75 mega-byte database size
maximum of 80 services and maximum 4 days of raw value data storage and maximum 150 mega-byte database size
maximum of 160 services and maximum 4 days of raw value data storage and maximum 300 mega-byte database size
Anything beyond that you will have not good results
beyond that you need a separate x86 device to host the dude
for big networks multiple virtualized instances of the dude will be needed, ssd storage etc etc
always keep the dude database size under 500mega-byte to keep good performance
