I am planing a cluster for a scientific application. I want to use 4 nodes and set up an HA cluster. The nodes have 6 NIC (1GbE) each.
Now I want to add redundancy for each network component. The primary focus is to get the cluster network redundant.
Right now I do not have a switch, but I have to keep costs in mind. I thought about buying used HP 3400cl or new Cisco SG300-20 hardware.
I have the following setup in mind:
DRBD network: 1x cross over between 2 nodes
cluster network : Proxmox (Bond) => 2x switch A, 1x switch B (Backup device)
vm's network: Promxox (Bond) => 1x switch A, 1x switch B
Switch to Switch connection with 2 cables (Tunk)
switch A => 2x (Trunk) datacenter switch
switch B => 2x (Trunk) datacenter switch
I have been using bonding on linux machines for a while, but have no experience with implementing it on switch level.
The question is, what is needed (and has to be configured on proxmox and the switches) to get this done.
Thanks for your thoughts
