…nic-net#19681) A new SKUs for MSN4700 Platform: Mellanox-SN4700-O32 and Mellanox-SN4700-V64 Requirements for Mellanox-SN4700-O32: 8 x 400Gbps uplink to T2 switch (O13 to O20) 24 x 400Gbps downlinks to T0 switch (O1-O12, O21-O32) Breakout mode No breakout mode. All ports working in 400Gb mode. . FEC mode: RS Type of transceiver: 400Gb Optical. warm boot should be supported “No for T1 role” VxLAN source port range set N/A Static Policy Based Hashing supported N/A Cable length “T0-T1 40m default, 300m max; T1-T2 2000m” Tradition buffer model is must “Yes” Shared headroom should be supported “Yes” Over-subscription ratio: “2”. Requirements for Mellanox-SN4700-V64 16 x 200Gbps uplink to T1 switch (V-25&V26 to V-39&40) 48 x 200Gbps downlinks to servers (Left panel downlink ports: V-1&2 to V-23&24; Right panel downlink ports: V-41&42 to V-63&64) Breakout mode split from 400Gbps ports (2x200) FEC mode: RS Type of transceiver: 200Gb AOC between T0 and T1; 200Gb DAC between T0 and host. warm boot should be supported “Yes for T0 role” VxLAN source port range set N/A Static Policy Based Hashing supported N/A Cable length “T0-T1 40m default, 300m max, T0-Server 5m” Tradition buffer model is must “Yes” Shared headroom should be supported “Yes” Over-subscription ratio: “2”. Additional Details: QoS configs for Mellanox-SN4700-V64 updated in order to fulfill Dual-ToR buffer (+DSCP remapping) requirements Support for independent module added for both SKUs, so Auto-negotiation changed to NO Signed-off-by: Andriy Yurkiv <ayurkiv@nvidia.com>
