I'm currently investing Spread vs JGroups vs Hazelcast, and had some
questions on Spread and networking.
I'm trying to provide some HA/redundancy to my application by mandating that
all nodes in the cluster, running this application should have multiple
NICs, each NIC connected to a completely different network (e.g. NIC1 on
network 10.1.3.*, NIC2 on network 172.16.1.*). This way, if one of the
networks go up in flames, there are redundant networks available to route
application traffic.
*Questions: *
1. Does Spread support this kind of network failover configuration?
2. In the case of a network fault (e.g. bad NIC, bad router), is there a way
to configure Spread so that it will failover communications to a working
interface on a given node?
3. Given the following network configuration, would all Spread nodes be able
to see each other:
- 1. Three nodes (node1, node2, and node3) in the cluster
- 2. node2 has two NICs (each on a different network)
- 3. node1 and node2 are connected through one network (e.g 10.1.3.*)
- 4. node2 and node3 are connected through a totally different
network (e.g 172.16.1.*)
Or is it a requirement that each Spread node should be reachable through the
network from all other Spread nodes?
Thanks in Advance!
