What is the performance of SmartX hyper-converged storage in the financial innovation scenario?

Preface

The quality of infrastructure determines people's safety and feelings. Just as a Boeing 747 cannot land safely on a runway made of inferior cement, no matter how excellent a business system is, it will not be able to perform adequately if it is not supported by an efficient and reliable infrastructure.

Thanks to its software-defined architecture and broad hardware compatibility, hyper-converged architecture has become the first choice for many financial users to promote IT cloudification and information innovation transformation. However, some users still have concerns about the application and performance of hyper-convergence in financial innovation scenarios, and hope to verify the real performance of hyper-convergence through more tests. This article will explore and verify the performance of Zhilinghaina SmartX hyper-converged Xinchuang cloud infrastructure through two scenarios (database scenario and general block storage scenario), so that users can have a glimpse of the performance level of hyper-convergence in Xinchuang scenarios. Two .

1. Zhilinghaina SmartX in financial innovation

With its professionalism and reliability in enterprise cloud infrastructure products such as hyper-convergence and distributed storage, as well as its ability to support mainstream domestic manufacturers, SmartX has been widely recognized by financial institutions. As of the fourth quarter of 2022, SmartX hyper-converged Xinchuang cloud infrastructure has become the choice of 40+ financial institutions, and has successfully implemented 700+ Xinchuang nodes, covering production (including office), disaster recovery, development and testing and other scenarios .

Among them, supported application types include:

2. Exploration of hyper-converged storage performance based on database scenarios

Data is the core asset of an enterprise. Nowadays, the storage and use of data require increasingly higher performance requirements on the infrastructure. The core of hyper-converged architecture is distributed storage. As a new generation of IT infrastructure, one of the most important criteria for evaluating hyper-convergence is whether it can efficiently support core business scenarios of enterprises such as databases.

值得注意的是,数据库对存储性能的综合要求,使得金融行业的客户不仅仅只关注 IOPS,而是需要存储在满足特定延时的基础上,也能够提供较高的 IOPS。经调研,延迟控制在 0.5ms 内,同时存储具备足够高的 IOPS,才能满足不同业务数据库对性能的极致要求。

综上所述,本次探索将存储延时限制在 0.5ms 范围内,来验证配置不同国产芯片(海光和鲲鹏)的 SmartX 超融合对数据库场景的支撑能力。本次测试设置 block size 为 8k(常见数据库),分别测试 100% 随机读、100% 随机写、7:3 混合读写、5:5 混合读写场景下 SmartX 超融合的性能表现。

经充分探索和性能评估,搭配国产芯片的 SmartX 超融合存储性能不仅能满足数据库场景的要求(指定延迟在 0.5ms 内),同时其在指定延迟下表现出的 IOPS 可充分应对绝大多数业务场景对性能的要求。

三、基于通用块存储场景的超融合存储性能验证

IT 基础架构信创转型,服务器虚拟化先行,但重点和难点在于存储。如上所述,超融合软件的核心是分布式存储,市场上主流的分布式存储产品有两类,一类是基于开源软件封装路线,代表产品是 Ceph,另一类是自主研发路线,SmartX 超融合的分布式存储组件属于此类。

某金融机构综合评估后,选择在海光平台上,基于某国产超融合产品(Ceph)和 SmartX 超融合产品进行全面的选型评估,并在存储性能维度上制定了以下几个评估要点:

  • 存储基准性能(性能越高越好)。

  • 扩容存储节点性能可做到线性增长。

  • 存储空间利用率在高低负载下的性能抖动(抖动越低越好)。

  • 长时间压测存储性能抖动(抖动越低越好)。

该场景测试 3 节点集群扩容 1 节点后,性能能否做到近似线性增长,3 扩 1 后如满足性能线性增长要求,性能提升比例为 33.3% 左右。

场景 3:高低负载存储性能对比

说明:低负载定义为存储空间利用率在 20% 以内,高负载定义为存储空间利用率 80% 以上。

场景 4:长时间压力测试对比

说明:测试时间 16h,蓝色为 SmartX 超融合性能表现,红色为某国产超融合(Ceph)性能表现。

3.测试结论

在主流国产国芯服务器平台上,与主流开源软件 Ceph 相比,SmartX 自主研发的分布式存储具备业内领先的存储性能,且节点扩容后性能近似线性增长。同时,存储性能的稳定性经受住了严苛的考验,在存储利用率高低负载和长时间压力测试场景中,性能抖动不明显
