Refer: https://forum.huawei.com/enterprise/en/smartqos-principles-and-features/thread/568269-891 Hello everyone, introduce the principles and features of Huawei SmartQos today. What is SmartQos ? SmartQoS helps set upper limits on IOPS or bandwidth for certain applications. Based on these upper limits, SmartQoS can accurately control the performance of these applications, thereby preventing them from contending for storage resources with critical applications. It provides the following functions: Assigns storage resources to critical applications on a preferential basis in the event of resource shortages in order to meet specific service level requirements across scenarios. Limits the resources allocated to non-critical applications to ensure better performance of critical applications. What working principles? I/O Priority Scheduling I/O priority sche...
