We're planning to upgrade our DC networks, 6 DCs in 3 different cities. Dark fibers within city, 2x10G WDM/L2VPN between each city. We've been offered Cisco ACI (2x 9332 + 4x9180 per DC) or Juniper (2xQFX5200+4x5110/5120). Running mostly HCI stuff so no need for that many ports or SAN network.
We run our own MPLS network in the campus and between cities, currently the WDM/VPLS links are connected to our DC PEs (switches that don't support EVPN/MPLS) that handle all the routing in the DCs. Wondering if we actually need a device capable of doing EVPN/MPLS or could we just connect the current WDM/VPLS links to our DC switches and run our MPLS over that? And just run L3 between VXLAN fabrics. For Juniper we would need MX204 for DCI if we plan to do EVPN/MPLS.
Juniper is about 15% more expensive if we compare the switches only (Cisco price includes ACI controller and switches). Not sure what kind of routers we would need for ACI.
Any ideas or thoughts?
