[Ask] How many oversold that allowed for OpenVZ node?
Hi all,
I have dedicated server with this spec's
Intel Quad core x3460, 16GB of RAM, 2TB (Raid-1) disk, 10TB monthly bandwidth on 1 gbps shared uplinks...
I create a VPS plan which have 512MB of guaranteed ram (may be with 768MB or 1GB busrtable ram) & 300GB monthly bandwidth.
How many vps can be created in terms of safely oversold for RAM, Bandwidth and CPU?
Thanks in advance
-sorry for my bad english-
regards,

You should host 16 - 24 VPS, depending of the burstable RAM you offer. Do not oversell. You will run into troubles.

When you have 30 VM's you will have this for every VM (without overselling):
* 512MB RAM
* 60GB HDD
* min. 30Mbit (when everybody max it!)
* 341GB traffic
* CPU: 0,25 So 1/4'the of a core
But leave some space for customers with more needs. (when they want to upgrade)
It all depends on what you want to do. Here every VM with a dedicated core, but the price will be different ... (Xen virtualisation)Tim Bracquez

The only other issue I see here, is that you're only using 2x2tb drives in raid 1. A 4 drive raid 10 of 1tb drives will offer at least double the performance with the same amount of disk space. This will allow you to fit more users on there before everything starts to run slowly.

As others have said, limiting is important. We have had many customers switch over to us because their old provider kept going out. Probably because they were overselling.

Yeah, you will reach the I/O limit of those hdds pretty soon. Raid10 may help you a little bit but far from double the IO.
Everything else looks ok, your first bottleneck will be the hdds. Keep in mind that there is no option to limit IO for a VM (ioprio is overrated) so any VM can bring your node to an unusable state and it will be pretty hard to figure out which of the VMs is responsible.

When we built out our first node, we had an Intel C2Q Q9550 with 8GB of RAM and 2x1TB RAID 1. We fit about 20 VMs on that box before things started falling down around us. Not sure with your CPU/RAM though.

I think with time you will see how much VPS's you can add, how much VPS's you can delete.
There will be costumers that use less resources then the allocated ones, and there will be costumers that use more then the allocated resources.
So, my sugesttion is actually when you think that you reached the max, you just stop adding and buy another machine to host more Virtual Private Servers.Best Regards / Melhores Cumprimentos,

Be careful with overselling. Because most sites will grow over time, you`ll run into troubles sooner or later if you oversell to much.

Of course you can always use the live migration features of xen when you are reaching your limits.
I also believe you will hit your IO limit first... maybe you want to investigate if your hw supplier/datacenter offers nas boxes which can be used for storage. I'm not sure if someone ran vps systems on nas storage, I'd be very curious too ...Need XEN Hosting? www.topxen.com

what do you mean multiple people? Like multiple vps systems on a server or more?
