Stack ring topology or routed access

Hello, I’m going to set up a news wired/wifi LAN. With a budget of 10k€ and all the SMF fiber uplinks going to one cabinet, I have selected a bunch of switches that will be placed all around an industrial plant: - 2x aruba 2930F 24G POE+ 4SFP+ - 1x aruba 2930F 48G POE+ 4SFP+ - 1x aruba 2930F 8G POE+ 2SFP+ plus six aruba AP-515.

My plan is to go “core-less” AKA a ring topology (every uplink is already on a single fiber closet) because we don’t have the budget for a stack of 2930M with sfp and stack modules or for a full-sfp 3810M, so there are two alternatives in my mind: - stack everything together - L3 routed access What I should choose to maximize manageability?

Second issue, I don’t know much of the aruba world, what software do I need to manage effectively all this hardware? Maybe aruba central? How does it works?

I know I should prefer a collapsed core topology in almost any case, but we need this port count in different closets and all the PoE and unified management stuff, that’s why I’m considering a ring.

Thanks in advance to everybody that will throw a rock there.
