1. Performanceo Within Data Centres
o Server performance grown well beyond single 10G interfaceo Storage getting faster thanks to SSDs
o Within Metro WANso Aggregation capacities moving from 10G 100G… Driving
Access points to evolve from 1G 10G, and 10G 25G2. Costs
o Less expensive to use a single 25G interface than 2 x 10G or 1 x 40G (4 of 10G lanes)
o Significantly reduce Ethernet switches required
Why “25 is the new 10…. 50 is the new 40”
25G provides higher throughput through lane capacity expansion instead of lane aggregation
