How many openVZ vps on a server?
Just being curious (No I don't plan to sell anything; got a job and no time for this.);
Lets say I have a root server with an i7-920 - or a XeonE3 if that's a big difference(?), - 24GB ram - how many 128MB openVZ vps could I run on it? Like they should run with decent speed.

By your words, I take you are looking at Hetzner. The bottleneck will be the HDDs, before reaching the limits of the CPU / RAM. Also the IPs will be problem as well, as they are expensive at hetzner. With good HDD configuration, an E3 server can handle a LOT 128 VMs.
lol yes; was the first one that came to my mind and I just looked for the cpu/ram of a few root servers. (How did you see that?)
What is a lot? I have no idea of this field; 10, 50, 100 ?
The whole problem is playing the resource balancing game. You have 4 major resources, CPU/RAM/HDD Space/HDD IOPS. An E3-1230 onwards should handle better than a 920 in the CPU department. RAM as you said 24GB, gives you about 192 VMs, or 180 VMs to be in the safe zone. Problem is at 180 VMs, your CPU is going to be 4 core 8 thread, which will literally go to hell if half of the VMs are actively churning stuff. Not to mention IOPS will be an issue at 180VMs as well. If you assume that each VM needs an average 5 IOPS constantly, that's 900 IOPS to factor in. One drive is capable of between 70-100 IOPS, you're going to need 9 drives (18 drives if RAID10) to be safe.
Of course if all those 128MB VMs were doing nothing then even 200 VMs would be a problem, but unless you can control each and every one of your customers, you can't avoid trying to play the balancing game.
The more experienced LEB hosts would probably be able to give you more actual figures, I'm still pretty new in the LEB market. Most of my experience revolves around 512MB+ VMs at my main company, so I'm not sure if my figures are overinflated.
40,000
@Kenshin I agree with the things you've said. SAS drives can be used for improved IOPS with less HDDs, as 18 drives RAID10 will be an overkill. I asume that atleast half of the VMs will be IDLEing, so I'd shoot at 150VMs hosted on a new E3 machine with carefully chosen HDD configuration.
I'm with jarland on this, 40,000 should be just about fine.
It depends. You need the 15k SAS or 10k Velociraptors drives to make a decent impact, and these are horribly expensive and reduce storage space at the same time. Again another balancing act involving costs vs capacity. Considering how CPU is going to also become a bottleneck, probably better off just running like 80-100 VMs so you only need 8 drives RAID10 and CPU won't be an issue.
In the past 12 years of providing hosting, I've learnt that assumption is a very very dangerous thing. Try hosting 80 cPanel VPSes on the same host node, then watch your host node die at 1AM daily due to cPanel's daily backup even though it's idle most of the time. Doesn't hurt as much at the start when the servers don't have much data, but over time is when things happen and accumulate.
I see your 80,000 and raise you 80,000
42
Over 9000?
maybe you should think about how many you wanna setup to decide to buy a dedicate servers.
Just overload the server with 1 billion vms
The people in a position to know are providers, and they're not going to come in here and tell you the degree that they're overselling their nodes.
I say 60 VPS's with 375mb ram 12gb HDD @ $4/month would be a good medium..
Breakdown:
i7-920 59 €
Flexi pack 15 €
/26 (62 IP's) 43.40 €
solusvm $10
Total approximate cost $160
60 vps's @ $4 = $240/month
so you make $80/month per server
60 vps's @ $4 = $240/month
of course this is in a perfect world when you fill the node on the first month and keep it full each month
Not to mention for all the possible work involved and making $80/month you'd probably be better off finding a full time job instead.
Yeah I'm sure after the tests are done people pretty much lose interest..
I forgot to include Paypal fees..
Well if $80 is not enough you could go for the /25 (126 IP's) so now you could do 190mb of ram @ $3/month
server with /26 = $206
124 clients @ $3/month = $372
$166/month profit per server
not sure how well the server would run with 124 VPS's
This might be slightly off-topic, how ever GoDaddy makes exactly $7672.32 per 48GB shared hosting server that costs them maybe $250/month. Now that's what I call profit!
166/month = 8.30/day (20 days /month) = 1.04/hour (8 hrs/day)
I'm sure MacDonalds pays more. Though you don't get to call yourself CEO.
@bamnael Sounds like you're following @subigo 's guide: http://www.lowendtalk.com/discussion/4473/how-to-become-the-ceo-of-your-very-own-vps-hosting-company-in-ten-easy-steps-and-for-under-200
@Jack if not, he's getting awfully close to it
The server cost $250/month but the girls with the big boobs that advertise their services must cost a bit more than that..
Not too many business where you can be profitable or at least break even in the first month!! most expect returns in 3 years..
But McDonald's is not scalable.. you are being paid time for money and since there is only one of you your potential to make money is very limited.
with a VPS you could get another server so now your making $166 x 2 you could even hire support.. you can't hire someone else to work for you at Mcdonald's!

True. But who would work for you for $166/month? Again that person would be better flipping burgers. Maybe at 7 servers, which would make that $7/hour, makes more sense. But that's 868 VPSes to sell, lol.
@earl I hate their commercials and their attitude towards their customers.
Fun trivia about GoDaddy shared servers:
@Kenshin then why bother doing any of this? You could earn $65K+ / year by driving an 18 wheeler, you would get 10 hours a sleep every day and 2 days off every week.
you guys also needs to market right?
Because if you succeed in the business, after a good number of years you can make 65K+/year by effectively watching your employees do the grunt work while you just make the decisions. That's when your deeply-hidden system admin senses/blood starts tingling due to the lack of hands-on work and you find LowEndBox/Talk, which makes you want to start all over again with this new concept of low end VPS servers.
True story.
@Kenshin It is a good concept and I was thinking about setting up a 64GB+ 12 core server with a RAID-10 array just for this community, but then I'm thinking about the stupid IPv4 limit. I guess that before I do anything I will poll the community.
@jcaleb I guess their marketing budget is Zero, and it's not a bad thing. Most companies spend more on advertising than on the services that they provide -> hint !GoDaddy! hint
