Traditional NFVi high performant dataplane deployments rarely focus on availability & consumption of dark resources such as CPU Cache and Memory Bandwidth. Much of the Quality of Service fine tuning often leads to over-subscription ending up with shared resource contention often termed as noisy neighbor effects. We present the architecture, methodology and test scenarios using open source solutions - OPNFV-VSPERF Framework, Collectd monitoring solution, Stress-NG workload generator and Resource Management Daemon client for (a) analyzing the performance impact due to presence of noisy neighbors and (b) controlling resources like Last Level Cache (LLC) for consistent & deterministic performance & availability in the presence of noisy neighbors.
