Observium uses RRD to store data. The size of the RRD files will not grow after creation so there is no archiving concern. Data will just get averaged out as it ages. What I would be more concerned with is IOPs rate of your storage. RRD has to do lots of small writes to every file on every polling run. I think that the current suggested method for large sites is a RAMdisk that is flushed to spinning disk every hour or two. That many devices would require quite a bit of ram. I'm using a RAID10 setup with 6 10k SAS disks and it keeps up pretty well, but I only have 266 devices. You might want to think about splitting up your servers.

Hey everyone;
I mentioned in a previous e-mail that we’re rolling out a deployment of Observium, and we absolutely love the product. I know that it’s designed as a historical data gathering tool, but I am concerned about the storage requirements for the system. I have approximately 600 routers and switches on my campus, and eventually would like to get my servers involved (pushing the device count beyond two-thousand), and I’m concerned at the storage requirements for this. I couldn’t find this information anywhere online, so I figured I would check with you guys.
Does Observium have any kind of roll-over archiving for device history beyond a certain point, or will it continually just grow the data in the files?
