Abstract

The emerging high-speed storage technologies increasingly use Nonvolatile Memory Express (NVMe) protocol to meet their high throughput and low latency needs. In a datacenter environment, applications accessing multiple such devices over the fabric (i.e. the network) tend to have Quality of Service (QoS) requirements pertaining to offered throughput and experienced latency. In this paper we describe a networked storage system simulator called NeSt that supports end-to-end (E2E) QoS differentiation across multiple classes of service. This is done by conveying the class designation end to end and using it to consistently but independently apply the differentiation in each segment of the path. We demonstrate the ability of NeSt to provide end-to-end QoS differentiation under a variety of situations. To the best of our knowledge, NeSt is the first simulator of networked storage (consisting of multiple NVMe SSDs) that supports E2E QoS differentiation.
NeSt:服务质量差异化端到端网络存储模拟器
新兴的高速存储技术越来越多地使用非易失性存储器 Express(NVMe)协议来满足高吞吐量和低延迟的需求。在数据中心环境中,通过结构(即网络)访问多个此类设备的应用往往对提供的吞吐量和体验的延迟有服务质量(QoS)要求。在本文中,我们介绍了一种名为 NeSt 的网络存储系统模拟器,它支持跨多个服务等级的端到端 (E2E) QoS 区分。这是通过端到端传递等级指定,并利用它在路径的每个段落中一致但独立地应用差异化来实现的。我们展示了 NeSt 在各种情况下提供端到端 QoS 区分的能力。据我们所知,NeSt 是第一个支持 E2E QoS 区分的网络存储(由多个 NVMe SSD 组成)模拟器。
