Just wondering what the is largest number of host machines that a proxmox cluster has reached so far? Just trying to get an idea of how it scales up and when the cross-node communication starts to become slower/impractical.
I'm also curious what kind of vps's you all run and on what hardware.
If you run 9 vps's, are these fully loaded webservers or just a single joomla install for instance.
@Marco114, I use Supermicroservers but run into severe io limitations, so make sure you test that before buying a heap of hardware.
@Clusterhq: How are those Atom 330 servers running? Thinking about a backupserver with a Atom 330.
First post!
I have a 7 server setup for a test bed before launch:
2 Masters rsynced (Intel Atom 330 - 2GB DDRII - 750GB SATAII)
- Master 1 - 2 VMs rdns1/ns1 & ISPConfig 3 Master
- Master 2 - 2 VMs rdns2/ns2 (w/ script to change IPs and host name) & copy of ISPConfig 3 Master (stopped state)
-- Master 2 monitors (pings) Master 1 - If no response for 15 seconds takes over rdns1/ns1 IPs and host names and updates the DNS entries and starts the ISPConfig 3 Master copy. DNS servers run MyDNSConfig.
2 Slaves each with 20 running VMs (Supermicro - Intel i7 920 - 12GB DDR3 - 2x 1.5TB SATAII Raid-1)
- All ISPConfig 3 Slaves
-- More of these and some in different DCs to come
2 Off Site DNS & HAProxy (Intel Atom 330 - 2GB DDRII - 250GB SATAII)
- Off Site 1 ns3 rsynced from master 1 - LB1 (HAproxy)
- Off Site 2 ns3 rsynced from master 2 - LB2 (HAproxy) rsynced from LB1 and scripted
1 Backup Server - (Supermicro - Intel Atom 330 - 2GB DDRII - 4x 1.5TB SATAII)
- NFS mount /backup on all servers
More Slaves to be added after launch. This is a setup for a HA hosting service. We are really just waiting on v2 of proxmox before we launch. We would really like a user interface and or API for proxmox before launch so we can more easily offer VM hosting as well. I think an API would be best as it would be easier for the devs to implement and we could keep our clients out of our management systems.
Besides the above proxmox has been running like a champ through multiple tests and is the best so far out of all the solutions we have tested.
