High availability / What means "same hardware" for HA
« on: April 27, 2024, 04:22:44 pm »
For an HA configuration, the exact same hardware is required, as is said time and again. What exactly does that mean?
Do the boxes have to be exactly the same, or is it only important that the order of the interfaces is correct?
LAN = LAN
WAN = WAN
OPT1 = OPT1
OPT2 = OPT2
What does this mean for virtual machines? For example, if one is running on VMware ESXi and the other on KVM/QEMU? Does this work or not, because it is not the same “hardware”?
Or if e1000 is used as the interface in one VM under VMware ESXi and VMXNET3 in the other?
