Configuring SmartQoS
Before configuring SmartQoS, understand the SmartQoS configuration process and obtain the I/O characteristics of file systems by using the service monitoring function of storage systems. Then configure SmartQoS policies based on the I/O characteristics to control storage resources allocated to applications, thereby ensuring continuity of critical services.
- Configuration Process
This section describes the SmartQoS configuration process. - Monitoring Application Performance
The storage system's built-in performance monitoring function provides visibility into object performance. This function helps you know the service level agreement (SLA) requirement of each application and adjust the performance goals of SmartQoS accordingly, thereby ensuring performance of critical services. - Configuring I/O Priorities
The I/O priority of a file system is determined by the importance of applications processed by the file system. There are three I/O priorities available: high, medium, and low. - Creating a Traffic Control Policy
A traffic control policy is a group of I/O classes and their performance goals, telling a storage system what performance targets the I/O classes have and how to achieve those goals.
