IOPs and/or MBps Limits (maximums)
QoS is a means to ensure specific performance levels for applications and workloads. There are two ways to accomplish this:
1. Ability to set limitations to avoid unwanted behavior from non-critical clients/hosts.
2. Ability to set guarantees to ensure service levels for mission-critical clients/hosts.

VxFlex OS currently supports only the first method.

VxFlex OS Limiter: Users can adjust the amount of IOPs and/or bandwidth (MBps) that one SDC can generate for a volume. These parameters are configured using the VxFlex OS CLI (Command Line Interface), and the REST interface, on a per client/per volume basis.
