Overview
SmartQoS is an intelligent QoS control feature developed by Huawei that dynamically allocates a storage system's resources to meet specific performance goals of certain applications.
SmartQoS extends the Information Lifecycle Management (ILM) strategy of a storage system. It is an essential add-on to a storage system, especially when certain applications have demanding SLA requirements. In a storage system shared by two or more applications, use of SmartQoS derives the maximum value from the storage system:
- SmartQoS controls the performance level for each application, avoiding conflicts between applications and ensuring the performance of critical applications.
- SmartQoS prioritizes critical applications in storage resource allocation by limiting the resources allocated to non-critical applications.
SmartQoS is supported for both LUNs (block services) and file systems (file services).
