Increasing network bandwidth delivers limited performance gains. Find out what key areas to focus on instead to reduce latency and congestion, and to improve workload completion times.

It's not how many gigabits you have, but how you use them.
It’s not uncommon for 90% of the traffic in traditional spine-leaf architectures to be routed through 20% of the links, creating route collisions and driving up congestion.
Increasing bandwidth doesn't resolve the efficiency problem, but makes it easier for more data to travel over the network faster on its way to the switches - increasing congestion and workload latency.
Oversubscription compounds the problem for both scale & budget.
Cerio makes it possible to extend PCIe beyond the compute node – and the compute rack – to provide configurable, efficient row-scale computing that changes the economics of the data center.
