Four nodes cluster

[Juve]

Hi all,

Has anyone already setup a four nodes cluster ?
In a situation where I have two physical location, connected at layer 2 with redundant path, I am planning to install two nodes on each site in order to have full redundancy.
Is this supported ?

I mean, if I configure the second node to replicate its settings to the third one and the third one to the fourth, will the carp interface have a priority higher than 100 on the third and fourth ?

Thanks
:-)

This is interesting,

I've never heard of a replicated firewall installation across different locations before

Wouldn't there be some settings that would need to be different? Why would the states need to be shares over multiple sites?

It is a highly critical datacenter (healthcare systems with critical patients at the other end of the wire) splitted on two sites (10 minutes by car)

Two sites but one network, I have full layer 2 continuity between the sites, over two physical path.
Sites are in active/active mode :

• same network
• servers (physical or vsphere VM) are in active/active or active/passive failover
• SANs (mostly VMware datastores) are replicated with on-the-fly failover(datacore) over 8gb/s fiberchannel links (two fabrics per site, two physical path)

Internet and mpls access are provided through optic fiber with layer 2 continuity/failover (plus copper backup) between the sites. Internet peering is also secured with BGP failover over another ISP (copper + fiber).

At this moment I have only one firewall per site, I'm thinking of how to have two firewall per site.
