Apologies in advance if the title is confusing, I’m not sure if that’s the best way to phrase my question… I have some servers running at a datacenter (Leaseweb New Jersey if it helps). They all have dedicated IPv4s in the same IP block. Since the storj algorithm favors geographical diversity, I assume each storj node I were to add would be competing against each other to some degree. In your opinion, how many storj node can I run before the increase of the overall utilization is no longer linear (Let’s say if running only 1 node it fills its hard drive in 6months, I want to stop when each node fills its hard drive in 9 months)? Are there any experiments I can do to find out? The servers don’t have spare storage space at the moment but spare hard drive bays. I’ll need to buy some second hand drives, so I can’t just do it and see what happens. ---

Hello @kommie1949 and welcome! One tool you can checkout to estimate how long it’s gonna take to fill up space is this community-made estimator: > [@Realistic earnings estimator](https://forum.storj.io/t/topic/6693/1): > > The original earnings estimator is no longer online, so I’m altering this suggestion to advocate for the return of a realistic earnings estimator. In the mean time SNOs can use this community version to get a good estimate of the earnings potential. Please be respectful of others using this sheet. If someone else is looking at their results, give them a moment before overwriting their inputs or copy the sheet to your own Google account to fill in your own inputs. The sheet is protected against … All nodes behind a /24 subnet are all considered as one. Which means that if you’ve got 1 node behind IP a.b.c.d getting 4GB/day (e.g.), adding 1 another node as a.b.c.(d+1) would split the traffic between the two (that is 2GB/day each). Overall, you wouldn’t get anymore data. On the other hand, if you’re able to run each node on a different /24 subnet, then you’re very lucky and each one would get full ingress traffic. I reckon adding more nodes in different /24 subnets wouldn’t really impact your other nodes traffic wise, unless you add like hundreds of nodes… ---

Very interesting! Thanks for letting me know. I think that gives me a pretty good idea.
