Buffer size has nothing to do with feature richness. Assuming you are asking about DC - in a wide radix low oversubscription network shallow buffers do just fine, some applications (think map reduce/ML model training) have many to one traffic patterns and suffer from incast as the result, deep buffers might be helpful here, DCI/DC-GW is another case where deep buffers could be justified.

Once again, which is better shared buffer featurerich or fat buffer switches? When its better to put big buffer switch? When its better to drop and retransmit instead of queueing?
Thanks. Dmitry
