Abstract: Techniques are provided for managing, within a storage system, the sequence in which I/O requests are processed by the storage system based, at least in part, on a one or more logical characteristics of the I/O requests. The logical characteristics may include, for example, the identity of the user for whom the I/O request was submitted, the service that submitted the I/O request, the database targeted by the I/O request, an indication of a consumer group to which the I/O request maps, the reason why the I/O request was issued, a priority category of the I/O request, etc. Techniques are also provided for automatically establishing a scheduling policy within a storage system, and for dynamically changing the scheduling policy in response to changes in workload.

Abstract translation: 提供了技术，用于至少部分地基于I / O请求的一个或多个逻辑特性，在存储系统内管理由存储系统处理I / O请求的序列。 逻辑特征可以包括例如提交I / O请求的用户的身份，提交I / O请求的服务，I / O请求所针对的数据库，消费者组的指示 I / O请求映射到哪里，发出I / O请求的原因，I / O请求的优先级等。还提供了用于在存储系统内自动建立调度策略，并且为了动态地 根据工作负载的变化改变调度策略。
