Each I/O scheduler has a default set of tunable options that may be adjusted to help improve performance or fair sharing for your particular use case. The following kernel documentation covers these per-I/O scheduler tunable options: deadline (and mq-deadline) deadline-iosched.txt cfq cfq...
Sio is a mix between noop & deadline. No reordering or sorting of requests.Advantages:Simple, so reliable.Minimized starvation of requests.Disadvantages:Slow random-read speeds on flash drives, compared to other schedulers.Sequential-read speeds on flash drives also not so good.6) V(R)Unlike ...

This is false. It might appear that way at first glance because individual components (etcd, kube-apiserver, kube-controller-manager, kube-scheduler, kubelet) each run in their own process, but the overall footprint in terms of CPU, memory, and disk space will be higher. ...
