I am planning to create a new infra MaaS 2.9 for three Datacenters, each containing about ~500 servers.
I am wondering how many Rack Controllers should I create and what should be the minimum requirement for this infra.
As I read here :
One rack controller can handle 1000 servers, so ideally:
- One global region controller
- Three rack controllers.
(No need for high availability.)
Or maybe You suggest to create more controllers ? Do You have any experience ?
Rack controllers will have :
4GB of ram
A lot of disk space
Finally, do You know how many OS Deployments in parallel MaaS can handles at once ? I do not want to Deploy servers one by one but rather use the API to do bulk actions.
Thank You in advance for Your help.
