Buffer Details
The Trident II has 12 MB of on-chip packet buffer. The memory is split between dedicated per-port buffers and a dynamic shared pool. Most of the memory is in the shared pool. A single congested port can absorb up to 8 MB of the shared pool dynamically.
See the Trident II architecture page for more details.
