基于华为高端NAS存储双活的POC测试

基于华为高端NAS存储双活的POC测试【摘要】近年来，银行业积累了越来越多的非结构化数据，在业务场景和存储系统建设上都在不断进行优化。

本文以作者所在企业的业务需求以及存储系统优化实际出发，在高端NAS存储双活系统上线前进行了深度POC测试。

从双活系统组网、架构健壮性以及业务系统适配上进行了多维度的测试，并形成了本POC测试报告，最终作为行里高端NAS双活系统规划和建设的依据。

1. 项目背景我行自2018年开始建设NAS存储资源池，从而正式开启了业务数据的存储架构优化之路，对于文件类的数据由先前的GPFS向NAS存储逐步迁移转型。

此外，结合存储系统分级体系建设以及业务系统的分级标准，在NAS存储资源池建设上同样也进行了分级存储建设。

为此，近两年来随着新核心系统的建设我行开始调研并构建高端NAS存储资源池。

同时，在同城双中心构建高端NAS存储的双活架构以满足我行新核心、重要及重要支撑系统的文件共享需求及其文件的高可用需求。

然而，高端NAS双活在我行首次实施，无论是该技术本身在我行网络架构中的适配性，还是在业务场景中的匹配上，甚至是存储运维人员对于这一新技术的全面掌握上都存在不确定性，甚至是盲点。

因此，运维部门作为该项目建设的牵头部门，开展了深度的高端NAS双活POC测试。

2. 测试目的和测试思路本项目计划通过深度的POC测试对高端NAS双活系统在应用场景、安全性以及功能性上进行充分验证，然后形成详尽的POC测试报告，最终作为高端NAS双活系统的规划和建设依据。

测试目的主要包括以下方面：第一，验证高端NAS双活架构在我行分区域建设的网络架构中的组网可行性。

第二，验证高端NAS双活架构在各种单点和双点故障场景中的自身架构健壮性。

第三，验证基于细粒度的单个业务系统的计划性站点切换演练的易用性和安全性。

对于POC测试原则最重要的是真实模拟或尽量贴近生产实际，因为在客户真实环境中的POC测试是最有说服力的，尤其是网络环境的真实性。

Conventional SAS-based all-flash storage cannot break the bottleneck of 0.5 ms latency. NVMe all-flash storage, on the other hand, is afuture-proof architecture that implements direct communication between the CPU and SSDs, shortening the transmission path. In addition, the quantity of concurrencies is increased by 65,536 times, and the protocol interaction is reduced from four times to two, which doubles the write request processing. Huawei is a pioneer in adopting end-to-end NVMe architecture across the entire series. OceanStor Dorado all-flash systems use the industry-leading 32 Gb FC-NVMe/100 Gb RoCE protocols at the front end and adopt Huawei-developed link-layer protocols to implement failover within seconds and plug-and-play, thus improving the reliability and O&M. It also uses a 100 Gb RDMA protocol at the back end for E2E data acceleration. This enables latency as low as 0.05 ms and 10x faster transmission than SAS all-flash storage. Globally shared distributed file system: The OceanStor Dorado 8000/18000 high-end all-flash storage systems support the NAS function and use the globally shared distributed file systems to ensure ever-fast NAS performance. To make full use of computing power, the many-core processors in a controller process services concurrently. In addition, intelligent data prefetching and layout further shorten the access latency, achieving over 30% higher NAS performance than the industry benchmark.Linear increase of performance and capacity: Unpredictable business growth requires storage to provide simple linear increases in performance as more capacity is added to keep up with ever-changing business needs. OceanStor Dorado8000/18000 support the scale-out up to 32 controllers, and IOPS increases up to 21,000,000 linearly as the quantity of controller enclosures increases, matching the performance needs of the future business development.Always-On Applications with 5-Layer Reliability Industries such as finance, manufacturing, and carriers are upgrading to intelligent service systems to meet the strategy of sustainable development. This will likely lead to diverse services and data types that require better IT architecture. OceanStor Dorado 8000/18000 high-end all-flash storage systems are an ideal choice for customers who need robust IT systems that consolidate multiple types of services for stable, always on services. They ensure end-to-end reliability at all levels, from component, architecture, product, solution, all the way to cloud, supporting data consolidation scenarios with 99.99999% availability.Benchmark-Setting 5-Layer ReliabilityComponent –SSDs: Reliability has always been a top concern in the development of SSDs, and Huawei SSDs are a prime example of this. Leveraging global wear-leveling technology, Huawei SSDs can balance their loads for a longer lifespan of each SSD. In addition, Huawei's patented anti-wear levelingtechnology prevents simultaneous multi-SSD failures and improves the reliability of the entire system.Architecture –fully interconnected design: Huawei OceanStor Dorado 8000/18000 use full-interconnection design at front and back-ends and intelligent multi-protocol interface modules to build the SmartMatrix architecture with ultra-high reliability. High-speed interconnection of multiple controllers is supported via the 100 Gb/s RDMA protocol, and the uniquefull-interconnection design tolerates failures for 3 out of 4 and even 7 out of 8 controllers and failure for 1 out of 2 controller enclosures to ensure zero service interruption, setting a new benchmark for storage reliability. The front-end interface modules connect to 4 controllers simultaneously. If a controller fails, services can be switched to an operational controller in seconds, without any host link interruption or any impact on upper-layer services. Application servers can access LUNs through any controller, instead of just a single controller. Multiple controllers share workload pressure using the load balancing algorithm. If a controller fails, other controllers take over services smoothly without any service interruption. Product –enhanced hardware and software: Product design is a systematic process. Before a stable storage system is commercially released, it must ensure that it meets the demands from both software and hardware, and can faultlessly host key enterprise applications. The OceanStor Dorado8000/18000 are equipped with hardware that adopts a fully redundant architecture and supports dual-port NVMe and hot swap, preventing single points of failure. The innovative 9.5 mm palm-sized SSDs and biplanar orthogonal backplane design provide 44% higher capacity density and 25% improved heat dissipation capability, and ensure stable operations of 2U 36-slot SSD enclosures. The smart SSD enclosure is the first ever to feature built-in intelligent hardware that offloads reconstruction from the controller to the smart SSD enclosure. Backed up by RAID-TP technology, the smart SSD enclosure can tolerate simultaneous failures of three SSDs and reconstruct 1 TB of data within 15 minutes. In addition, the storage systems offer comprehensive enterprise-grade features, such as 3-second periodic snapshots, that set a new standard for storage product reliability.Solution –gateway-free active-active solution: Flash storage is designed for enterprise applications that require zero data loss or zero application interruption. OceanStor Dorado8000/18000 use a gateway-free A-A solution for SAN and NAS to prevent node failures, simplify deployment, and improve system reliability. In addition, the A-A solution implements A-A mirroring for load balancing and cross-site takeover without service interruption, ensuring that core applications are not affected by system breakdown. The all-flash systems provide the industry's only A-A solution for NAS, ensuring efficient, reliable NAS performance. They also offer the industry's firstRoCE transmission to improve performance by 50% compared with traditional IP solutions. In addition, the solution can be smoothly upgraded to the geo-redundant 3DC solution for high-level data protection.Cloud –gateway-free cloud DR*: Traditional backup solutions are slow, expensive, and the backup data cannot be directly used. Huawei OceanStor Dorado 8000/18000 high-end all-flash systems provide a converged data management solution. It improves the backup frequency 30-fold using industry-leading I/O-level backup technology, and allows backup copies to be directly used for development and testing. The disaster recovery (DR) and backup are integrated in the storage array, slashing TCO of DR construction by 50%. Working with HUAWEI CLOUD and Huawei jointly-operated clouds, the solution achieves gateway-free DR and DR in minutes on the cloud.Efficient O&M with Intelligent Edge-Cloud Synergy Intelligence throughout service lifecycle: Intelligent management covers resource planning, provisioning, system tuning, risk prediction, and fault location, and enables 60-day and 14-day predictions of performance bottleneck and disk faults respectively, and immediate solutions for 93% of problems detected.On and off-cloud synergy: Huawei OceanStor Dorado8000/18000 high-end all-flash systems combine general-purpose cloud intelligence with customized edge intelligence over a built-in intelligent hardware platform, providing incremental training and deep learning for a personalized customer experience. The eService intelligent O&M and management platform collects and analyzes over 190,000 device patterns on the live network in real time, extracts general rules, and enhances basic O&M.Extreme convergence: Huawei OceanStor Dorado 8000/18000 high-end all-flash storage systems provide multiple functions to meet diversified service requirements, improve storage resource utilization, and effectively reduce the TCO. The storage systems provide both SAN and NAS services and support parallel access, ensuring the optimal path for dual-service access. Built-in containers support storage and compute convergence, reducing IT construction costs, eliminating the latency between servers and storage, and improving performance. The convergence of cross-generation devices allows data to flow freely, simplifying O&M and reducing IT purchasing costs.FlashEver: The intelligent flexible architecture implements component-based upgrades without the need for data migration within 10 years. Users can enjoy latest-generation software and hardware capabilities without investing again in the related storage software features.Technical SpecificationsModel OceanStor Dorado 8000 OceanStor Dorado 18000 Hardware SpecificationsMaximum Number of3232ControllersMaximum Cache (Dual512 GB-32 TB512 GB-32 TBControllers, Expanding withthe Number of Controllers)Supported Storage Protocols FC, iSCSI, NFS*, CIFS*Front-End Port Types8/16/32 Gbit/s FC/FC-NVMe*, 10/25/40/100 GbE, 25 Gb NVMe over RoCE*Back-End Port Types SAS 3.0/100 Gb RDMA28Maximum Number of Hot-Swappable I/O Modules perController Enclosure96Maximum Number of Front-End Ports per ControllerEnclosureMaximum Number of SSDs6,4006,400SSDs 1.92 TB/3.84 TB/7.68 TB palm-sized NVMe SSD,960 GB/1.92 TB/3.84 TB/7.68 TB/15.36 TB SAS SSDSCM Supported800 GB SCM*Software SpecificationsSupported RAID Levels RAID 5, RAID 6, RAID 10*, and RAID-TP (tolerates simultaneous failures of 3 SSDs)Number of LUNs65,536Value-Added Features SmartDedupe, SmartVirtualization, SmartCompression, SmartMigration, SmartThin,SmartQoS(SAN&NAS), HyperSnap(SAN&NAS), HyperReplication(SAN&NAS),HyperClone(SAN&NAS), HyperMetro(SAN&NAS), HyperCDP(SAN&NAS), CloudBackup*,SmartCache*, SmartQuota(NAS)*, SmartTier*, SmartMulti-Tenant(NAS)*,HyperMetro-Inner(SAN&NAS), SmartContainer*DeviceManager UltraPath eServiceStorage ManagementSoftwarePhysical SpecificationsPower Supply SAS SSD enclosure: 100V–240V AC±10%, 192V–288V DCController enclosure/Smart SAS SSD enclosure/Smart NVMe SSD enclosure: 200V–240VAC±10%, 192V–288V DCTechnical SpecificationsModel OceanStor Dorado 8000 OceanStor Dorado 18000 Physical SpecificationsDimensions (H x W x D)Controller enclosure: 175 mm ×447 mm ×865 mmSAS SSD enclosure: 86.1 mm ×447 mm ×410 mmSmart SAS SSD enclosure: 86.1 mm x 447mm x 520 mmSmart NVMe SSD enclosure: 86.1 mm x 447mm x 620 mmMax. bay dimensions: 2000 mm ×600 mm×1200 mmWeight Controller enclosure: ≤ 90 kgSAS SSD enclosure: ≤ 20 kgSmart SAS SSD enclosure: ≤ 30 kgSmart NVMe SSD enclosure: ≤ 35 kg System bay: ≤ 700 kg Disk bay: ≤ 600 kgOperating Temperature–60 m to +1800 m altitude: 5°C to 35°C (bay) or 40°C (enclosure)1800 m to 3000 m altitude: The max. temperature threshold decreases by 1°C for everyaltitude increase of 220 mOperating Humidity10% RH to 90% RHCopyright © Huawei Technologies Co., Ltd. 2021.

3.1 系统架构3.2 块级虚拟化3.3 稳定可靠3.4 安全高效3.5 弹性融合3.1 系统架构3.1.1 后端全互连OceanStor 18000 V3系统高端存储系统每个引擎包含4个控制器，4个控制器直接通过机框无源背板上的PCIe 3.0高速通道互联，4控以内的配置不需要通过外部线缆和交换机，部署更简单，可靠性更好，性能也更好。

下面左图为引擎前视图，最上面是4个BBU，下面是4个呈“田”字分布的4个控制器；右图为引擎内部连接示意图。

图 1 OceanStor 18000 V3四控引擎示意图OceanStor 18000 V3高端存储系统使用SAS 3.0后端全互连接口卡，该接口卡由引擎4个控制器共享，与4个控制器都有连接。

某一个控制器发生故障时，引擎到硬盘框的连接仍然是冗余的，后端连接的可靠性不会降低。

下面左图为引擎后视图，中间4个槽位所插接口卡，即为后端全互连接口卡，高度为4U；右图为共享SAS接口卡的连接示意图。

图 2 OceanStor 18000 V3后端硬盘连接示意图OceanStor 18000 V3高端存储系统支持持续镜像（Persistent Cache）技术。

引擎中的4个控制器，正常情况下A/B控的Cache相互镜像，C/D控的Cache相互镜像。

当一个控制器故障后，假设B控故障，此时按照传统设计，为了保证数据可靠性，A控Cache将转为透写，性能急剧下降，而持续镜像技术会将A控Cache数据重新镜像到C或D控（由内部算法动态选择），以保证Cache数据可靠性，避免转透写带来的性能急剧下降。

3.1.2 PCIE Scale-OutOceanStor 18000 V3系列高端存储系统采取多控智能矩阵（SmartMatrix 2.0）架构设计，控制器之间采用PCIe光互联设计，实现控制器间的业务交换。

最大支持4引擎，每个引擎包含4个控制器，整个系统最大支持16个控制器。

每个控制器分别与2个交换平面通过PCIe光缆进行互连实现数据转发；此外，引擎内的4个控制器之间还可以通过引擎背板上的PCIe互联通道进行数据转发。

如下图所示：每个控制器在3号槽位配置一张PCIe接口卡，每张卡有两个PCIe光口，分别用光缆连接到两个PCIe交换机（为避免图中连线太多，引擎2/引擎3的线没有连）。

图 3 OceanStor 18000 V3 PCIe Scale-out示意图16个控制器通过QSFP光缆连接到两个冗余的DSW中，在DSW中实现数据交换，采用全PCIe的互联架构的优势在于减少协议转换的延时，可以实现更加高效的数据交换。

采用全光互联的设计一方面提高了长距离数据传输的可靠性，另外一方面对机柜之间的距离要求减少，有利于客户机房内部的机柜布局设计；每台PCIe交换机提供16个PCIe交换端口，每个端口4GB/s的交换带宽，两台PCIe交换机共提供128GB/s（2*16*4GB/s=128GB/s）的交换带宽；每个引擎内的4个控制器之间有128GB/s(PCIe3.0*64)的背板PCIe互联带宽，用于引擎内控制器之间的数据交换。

则OceanStor 18000 V3 16控配置下，总的系统交换带宽为640GB/s（引擎内交换带宽128GB/s*4+跨引擎交换带宽128GB/s=640GB/s）。

3.1.3 负载均衡默认情况下，系统自动将不同LUN均衡分配到不同控制器，LUN空间均衡打散到系统内所有硬盘。
