- Why I did it
A new SKU for MSN4700 Platform i.e. Mellanox-SN4700-V16A96
Requirements:
Breakout:
Port 1-24: 4x25G(4)[10G,1G]
Port 25-28: 2x100G[200G,50G,40G,25G,10G,1G]
Port 29-32: 2x200G[100G,50G,40G,25G,10G,1G]
Downlinks: 96 (1-24) + 4 (25-28)
Uplinks: 4 (29-32)
Shared Headroom: Enabled
Over Subscribe Ratio: 1:4
Default Topology: T0
Default Cable Length for T1: 5m
VxLAN source port range set: No
Static Policy Based Hashing Supported: No
Additional Details:
QoS params: The default ones defined in qos_config.j2 will be applied
Small Packet Percentage: Used 50% for traditional buffer model Note: For dynamic model, the value defined in LOSSLESS_TRAFFIC_PATTERN|AZURE|small_packet_percentage is used
SKU was drafted under the assumption that the downlink ports uses xcvr's that will only support the first 4 lanes of the physical port they are connected to. Hence for the ports 1-24, the last four lanes are not used
Cable Lengths used for generating buffer_defaults_{t0,t1}.j2 values
