== | An [http://files.opencompute.org/oc/public.php?service=files&t=4baf98af7f736844e149508321370650 improved version of survey template v02] is created. | ||
All NIC suppliers are strongly recommend to participate to influence Mezz 3.0. | |||
Inputs from System supplier and Hyper-scale/CSP are welcome as well. | |||
Agenda for next meeting (4/5) | |||
1. Review overall Mezz 3.0 work schedule | |||
2. Review the boundary with the context of major options | |||
3. Pick major option branches to perform more detailed study | |||
'''3/22/2017''' | |||
A survey of boundary condition of typical use cases is going on. | |||
Detail see [http://lists.opencompute.org/pipermail/opencompute-mezz-card/2017-March/000003.html here] | |||
