This model provides 36 QSFP ports, made up of 24 QSFP+ and 12 QSFP100 ports. It supports up to 12 x 100GbE, 36 x 40GbE, 48 x 25GbE or 120 x 10GbE using breakout modes, with 3.84 Tbps full-duplex throughput, 1.44 Bpps forwarding and latency from 3.8 us. An 8 GB packet buffer, Virtual Output Queues and AlgoMatch support demanding east-west and peering traffic. This SKU has front-to-rear airflow, 2 x 747W AC hot-swap power supplies in a 1+1 arrangement, four hot-swap fans and 8 GB of system memory.
