Bryan, Thanks for raising an important point. IMHO 2 NICs are the minimal setup. This allows for performance focused setups (i.e. traffic enters on one NIC and leaves on another NIC), and it also allows for setups where you use the NICs for different purposes (e.g. dedicate a NIC to the kernel, and another one to VPP).
We can of course handle all three "types" of networks (admin, public, tenant/private) using VLAN/VLAN-ranges - but for some deployments a physical decoupling might ease things. Per your suggestion: In order to allow for better flexibility, let's plan with 3 NICs for now. We can always scale back in case there are budget constraints. Lights-out-management is something that is often vendor specific - and it may, or may not require a dedicated port (IPMI 2.0 even runs over VLANs) - but as part of the requirements list, we should spell out that lights-out-management is something we absolutely require. I'll update the wiki accordingly. Thanks, Frank From: opnfv-tech-discuss-boun...@lists.opnfv.org [mailto:opnfv-tech-discuss-boun...@lists.opnfv.org] On Behalf Of Bryan Sullivan Sent: Dienstag, 15.

I thought the NIC requirements were more substantial. IMO we should require at least IPMI + 3 NICs (Admin/PXE, Private, Public). The lab we are building as described at https://wiki.opnfv.org/display/joid/MAAS+as+Lab+Admin+Server will be designed that way. Our vision for how we will use this lab (initially, for internal development/CI activities only) is very similar to your vision for LaaS dynamic assignment of server resources. We plan to use MAAS, Ansible, and Jenkins to manage the admin and distribution of development/CI/etc activities across these servers.
