Market research for a client project to find open compute (linux based) network switches

Our client requests expertise on getting used/refurbished open compute (linux based) network switches. You have already great expertise on open compute (linux based) switches? If so share us 2 good switches which fit to this requirement: - best price/value ratio - already or near EOL of the vendor - redundancy - 48 ports of 10G SFP or 48 ports 1G ports with at least 4 10G Uplinks - which open compute SDN is already installed Your task will be to create a comparission matrix of current and EOL products, which are available for open compute and which distributions of linux are supported along with the specification parameters each switch has (intern bandwidth, bandwidth per port-group, power consumption, price new, price used, ...) Do not apply if you have not at least 24 month of real hands on experience on open compute switch solutions. (you have to prove and to show us the administration of such a switch live, to prove your expertise) Please note we do not disclose our budget nor our hourly price rate, we are willing to pay. So please apply with your best offer to get considered.
