Edgecore AS7726-32X (DCS204)
The Edgecore AS7726-32X (also marketed as DCS204) is a pure enterprise and data center bare-metal top-of-rack (ToR) and spine switch. It is certified for several NOS platforms, notably including IP Infusion OcNOS.
| Field | Value |

| ASIC | Broadcom Trident 3 (BCM56870) |
| Total Buffer | 32 MB |
| Architecture | Fully Shared On-Chip |
Buffer Architecture
Unlike the deep-buffered Qumran family tailored for carrier routing, the AS7726-32X uses the datacenter-optimized Broadcom Trident 3 ASIC. It features a fully shared 32 MB on-chip packet buffer.
While much shallower than a router, the 32 MB pool is dynamically allocated across all active ports via a shared-memory threshold mechanism. This is optimized for east-west traffic flow within data centers where latency is prioritized over absorbing massive internet-scale TCP bursts.
