Soooo, I have been running my unicast Proxmox cluster for almost 2 years now with zero downtime and have been very pleased with it, but there are some things I would love to change and I now have the opportunity to do so.
We are about to get either GigE or 10GigE fiber installed in our office which means I can finally bring the cluster home instead of having to use dedicated server hosting through a supplier that does not provide multicast in a country thousands of miles away. This gives me more access, more control, more security and significantly reduces my costs.
But there is another side to this - using dedicated servers in a data center meant I didn't have to setup the network myself, I just had to configure the servers. Moving the servers to my office, I am going to need to setup the network for them so I was hoping I might be able to get some advice on this.
I will be starting with 3 nodes initially + 1 dedicated storage server and will potentially add new nodes in the future as required. My current setup is 3 nodes without any dedicated storage server so things are already going to be a little different from a configuration perspective but I want HA.
First things I need to consider is networking. I will need an 8 port managed switch for the multicast network with GigE on each port and I am unsure which one to purchase - there are a lot of them out there and I don't want to make a bad choice (should support IGMP Querier as well as IGMP Snooping too right?) - I have never setup a multicast network before so this is entirely new to me.
The servers will have 2 GigE ports each - one for the multicast internal network and one for containers/VPS that need public facing IP addresses - I presume this is a sensible approach to take? The non-multicast ports will connect directly to the gateway router. Currently my cluster is a mix of containers/VPS some which are only accessible on a private network via VPN and others which are public facing (web, DNS, mail etc.) and this will remain the case. Some of the containers/VPS are also connected to a second VPN so they can talk to each other (my database server is serving data to both private servers and public servers for example).
So I was hoping some of you might be able to recommend some SOHO managed switches which will give me full multicast support but won't cost me a kidney?
Also if anyone has any guides or links to resources beyond the wiki on setting up HA cluster I would appreciate it (I set my cluster up almost 2 years ago and it was non-trivial to say the least, it would be nice to find an up to date guide for Proxmox 5.*).
Thanks in advance for any help.
