Hi,

at CERN we have 3 regions regions with a total of 75 cells (>8000 compute nodes).

In the past we had a cell with almost 2000 compute nodes.

Now, we try to not have more than 200 compute nodes per cell.

We prefer to manage more but smaller cells.

Hi everyone,

As part of the Large Scale SIG[1] activities, I'd like to quickly poll
our community on the following question:

How many compute nodes do you feel comfortable fitting in a
single-cluster deployment of OpenStack, before you need to scale it out
to multiple regions/cells/.. ?

Obviously this depends on a lot of deployment-dependent factors (type of
activity, choice of networking...) so don't overthink it: a rough number
is fine :)

Thanks in advance,
