High-performance computing (HPC) storage systems become increasingly critical to scientific applications given the data-driven discovery paradigm shift. As a storage solution for large-scale HPC systems, dozens of applications share the same storage system, and will compete and can interfere with each other. Application interference can dramatically degrade the overall storage system performance. Therefore, developing a flexible and effective storage solution to assure a certain level of resources per application, i.e. the Quality-of-Service (QoS) support, is critical. One of the common solution to achieve QoS assurance for storage systems is using provisioning technique~cite{3}. Provisioning refers to the ability of providing certain amount of resources for applications and expected workloads. However, provisioning has limitations such as requiring the detailed knowledge of the expected workloads. addition, the storage workloads are transient hence expensive to be satisfied. Due to these limitations, providing QoS storage systems through provisioning is challenging. In this research, a software-defined approach~cite{0} is proposed as a flexible solution to achieve QoS guarantee for storage systems. The driving force of using a software-defined approach instead of the traditional approaches, is that it has the ability to enable a more flexible, scalable, and efficient platform. For example, if any changes occurred in the system, it does not necessarily need to re-configure thousands of devices; instead, with re-configuring a logically centralized component, other devices will be automatically notified. |
