Hi everyone,
We’ve heard rumors suggesting that an on-premises Cambium instance can only manage up to 1,000 clients—clients meaning actual end-user devices (not Cambium hardware).
We are currently planning to migrate 5 on-prem instances onto a single on-prem server so we only have to manage one server.
Is there any truth to these rumors?
We don’t really believe it ourselves, given that the account capacity alone is 25,000, but we want to double-check just to be sure.
Thanks in advance for your feedback!
Best regards,
Marco
We’ve more than 1000 currently:
Hi Andrew,
Thanks for your reply.
The unique clients only show how many distinct devices were connected over the last 24 hours, but not how many were connected simultaneously.
On our on-prem server, when I add the wired and wireless clients together, we reach between 800 and 900 end devices—though so far, it’s never been more than 1,000.
As I said, I don’t think there’s any truth to the rumors, but I’d still like to get it confirmed beforehand.
Do you get over 1,000 if you add the wired and wireless clients together?
Our cambium APs handle the radius auth so I wouldn’t think that they would care what is being shown on the cnMaestro dashboard. They will serve as many users as the hardware allows.
You can definitely have more than 1,000 clients.
Hi Mitchell,
Thanks for your reply and the picture.
What do the performance specs of your on-prem server look like? How much RAM and what CPU, etc., are you using?
We want to manage approximately 2,000 Cambium devices on an on-prem server with about 600 sites and roughly 1,000 SSIDs.
What requirements need to be met for this?
Best regards, Marco
@Marco_Schimo The cnMaestro install guide lists these requirements:
Historically Xirrus/Cambium (most vendors actually) recommend way more resources than they should simply to account for the sloppy/inefficient code of their application. Rather than produce a quality product they just tell their customers to “throw more hardware at it”. I never liked that model and in general, most of the systems I manage use less resources that the manufacture suggests.
In my case, my on-prem instance of cnMaestro is allocated 4 CPUs (older Xeon 4110 @ 2.1Ghz) and 6GB of RAM. That is currently managing 450 devices, and this morning it was reporting 8,000 unique clients. The system works fine and is not taxed at all, in fact, judging from the performances graphs, I could drop it down to 3 CPUs and still have breathing room.
