Why ARM Servers and Why Now?

Contributing Factor Trend in Data Center Arena

Economic & environmental

motivation to switch from

traditional approaches

Modest barrier to entry for new

solutions – prevalence of open

source in scale out deployments

Opportunity for innovation

Diversification of server

workloads mean one size

does not fit all

RAN Evolution

Trend: Cloud RAN (C-RAN)

•Benefit: Centralised macro BST with fibre

link to intelligent antennas

•Proposition: power efficient server,

signalling and control macro BST platforms

Trend: large & small cells in

heterogeneous networks

•Benefit: Increased QoE with better edge-

of-cell capacity

•Proposition: scaleable C-progammable

power efficient HW & SW BST platforms

Trend: RAN IT functionality

•Benefit: Reducing backhaul traffic &

improving QoE through distributed caching

and open-API cloud apps

•Proposition: energy efficient server

platforms

Network evolution challenges

• LTE topology: IP backhaul & flatter net

• Multiple RATs with intelligent antennas

• Higher frequencies

• Better QoS through local services

• Power consumption
