Abstract

Nowadays, solid-state drives (SSDs) have become the best choice of storage devices, when compared with hard-disk drives (HDDs). More and more scenarios adopt a multi-SSD architecture to improve performance and expand storage capacity for cloud services, database centers, distributed systems and virtualized environments. When multiple users (flows) are competing for shared multiple SSDs concurrently, if the multi-SSD architecture lacks a fairness strategy among multiple users, a user that takes up more resources can affect other users. Meanwhile, if the multi-SSD architecture lacks a load-balance strategy among multiple shared SSDs, some specific SSDs may receive too many I/O requests to degrade the performance and shorten the lifespan. Therefore, we will propose a state-aware method to consider flows with fairness on NVMe SSDs with load balance.

具有负载平衡的NVMe ssd上具有公平性流的状态感知方法

目前，固态硬盘(ssd)已经成为存储设备的最佳选择，而不是硬盘驱动器(hdd)。在云服务、数据库中心、分布式系统和虚拟化环境中，越来越多的场景采用多ssd架构来提升性能和扩展存储容量。当多个用户(流)并发竞争共享的多个ssd时，如果多ssd架构缺乏多用户间的公平策略，则某个用户占用资源较多会影响其他用户。同时，如果多ssd架构缺少多个共享ssd之间的负载均衡策略，可能会导致某些特定ssd收到过多的I/O请求，从而降低性能，缩短寿命。因此，我们将提出一种状态感知方法来考虑具有负载平衡的NVMe ssd上具有公平性的流。
