The experiences gathered with the deployment of Single VLAN architecture has been documented in the following Validated Reference Design: Single VLAN Architecture for WLAN.
This document is used by many customers to deploy single VLAN.
One of the things you should take care of is your wired infrastructure. If your environment grows large, the routers and switches you attach your controllers to should be able to handle a large number of MAC/CAM entries and ARP entries. I know a whitepaper on how to handle that with HPE Aruba switches is under development.
If you have urgent issues, please contact your Aruba partner or Aruba TAC.
