Arista Networks Converged Cloud Fabric 产品介绍说明书

Converged Cloud Fabric™Self-Service Automated Fabric with Cloud-Style VPCs ON-PREMThe CCF architecture consists of a physical switching fabric, which is based on a leaf-spine Clos architecture. Leaf and spine switches running Switch Light™ Operating System form the individual nodes of this physical fabric. Intelligence in the fabric is hierarchically placed—most of it in the CCF Controller (where configuration, automation and troubleshooting occur), and some of it off-loaded to Switch Light for resiliency and scale-out. Converged Cloud Fabric System Components• Converged Cloud Fabric Controller — a centralized andhierarchically implemented SDN controller available as anHA pair of hardware appliances for high availability.• Open Networking Leaf and Spine Switch Hardware— the term ‘open networking’ (whitebox or britebox)refers to the fact that the Ethernet switches are shippedwithout an embedded networking OS. The merchantsilicon networking ASICs used in these switches are thesame as used by most incumbent switch vendors andhave been widely deployed in production in hyperscaledata center networks. These bare metal switches ship with Open Network Install Environment (ONIE) for automaticand vendor-agnostic installation of third-party networkOS. A variety of switch HW configurations and vendors are available on the CCF hardware compatibility list.• Switch Light Operating System — a light-weight opennetworking switch OS purpose built for SDN• Converged Cloud Fabric Automation Plugins (optional) — Converged Cloud Fabric has built-in E-VPC networkautomation for private cloud platforms including VMware vSphere/NSX/vSAN, DellEMC VxRail HCI, Nutanix HCI,Microsoft Hyper-V, Kubernetes containers and OpenStack. Deployment SolutionsCCF is designed from the ground up to satisfy the requirements of physical, virtual or combination of physical and virtual workloads. It supports a wide variety of data center and private cloud use cases, including:• VMware SDDC workloads (vSphere, NSX, Virtual SAN andVIO)• Converged and Hyper-converged Systems (HCI) withNutanix and Dell EMC VxRail• Microsoft Hyper-V workloads• OpenStack including NFV• Kubernetes orchestrated containerized workloads• Virtual desktop infrastructure (VDI) workloadsFigure 1: Converged Cloud Fabric (One Logical Switch)Converged Cloud Fabric BenefitsCentralized Controller Reduces Management Consoles By Over 60:1With configuration, automation and most troubleshooting done via the CCF Controller, the number of management consoles involved in provisioning new physical capacity or new logical apps goes down dramatically. For example, in a 32 rack pod with dual leaf switches and four spine switches, a traditional box-by-box network design would have 68 switch management consoles. The Converged Cloud Fabric design has only one—the controller console—that performs the same functions. The result is massive time savings, reduced error rates and simpler automation designs. As a powerful management tool, the controller console exposes a web-based GUI, a traditional networking-style CLI and REST APIs.Streamlined Configuration, Enabling Rapid InnovationIn the CCF design, configuration in the CLI, GUI or REST APIis based on the concept of logical tenants. Each tenant has administrative control over a logical L2/L3/policy design that connects the edge ports under the tenant’s control. The Converged Cloud Fabric controller has the intelligence to translate the logical design into optimized entries in the forwarding tables of the spine, leaf and vleaf.Open Networking Switch Hardware Reduces CapEx Costs By Over 50%By adding up hardware, software, maintenance and optics/ cables, a complete picture of the hard costs over three years shows that the savings are dramatic.Built-in Orchestration Support Streamlines DC Operations CCF Controller natively supports integration with popular private cloud platforms—VMware vSphere/NSX/vSAN, DellEMC VxRail HCI, Nutanix HCI, Microsoft Hyper-V, Kubernetes containers and OpenStack—through a single programmatic interface. This is tremendously simpler and scalable compared to traditional box-by-box complexity networking which demands an exponentially larger number of programmatic interactions with CMPs. Data center admins benefit from streamlined application deployment workflows, enhanced analytics and simplified troubleshooting across physical and virtual environments.Figure 2: Example CCF Deployment Scenarios Figure 3: E-VPC Automation for Cloud Management PlatformsSDN Fabric Enables Deep Visibility and Resilience for OpenStack NetworksThe CCF OpenStack Neutron plugin for L2 networking provides resiliency necessary for production-grade OpenStack deployments. The CCF Controller acts as the single pane for provisioning, troubleshooting, visibility and analytics of the entire physical network environment. This enables data center operators to deploy applications rapidly, simplifies operational workflows and provides immediate root–cause analysis when application performance issues arise.Scale-out (Elastic) FabricCCF’s flexible, scale-out design allows users to start at the size and scale that satisfies their immediate needs while future proofing their growth needs. By providing a choice of hardware and software solutions across the layers of the networking stack and pay-asyou-grow economics, starting small scaleand growing the fabric gradually instead of locking into afully integrated proprietary solution, provides a path to a modern data center network. Once new switches are added, the controller adds those switches to the fabric and extends the current configuration hence reducing any error that may happen otherwise. Customers take advantage of one-time configuration of the fabric.DC-grade ResilienceCCF provides DC grade resiliency that allows the fabric to operate in the face of link or node failures as well as in the rare situation when the controller pair is unavailable (headless mode). Swapping a switch (in case of HW failure or switch repurpose) is similar to changing a line card in a modular chassis. After re-cabling and power up, the switch boots up by downloading the right image, configuration and forwarding tables. Additionally, the CCF Controller coordinates and orchestrates the entire fabric upgrade ensuring minimum fabric down time. These functionalities further enhance fabric resiliency and simplify ing CCF: A 3-Tier Application ExampleCCF supports a multi-tenant model, which is easily customizable for the specific requirements of different organizations and applications. This model increases the speed of application provisioning, simplifies configuration, and helps with analytics and troubleshooting. Some of the important terminology used to describe the functionality include:• E-VPC Tenant — A logical grouping of L2 and/or L3networks and services.• Logical Segment — An L2 network consisting of logicalports and end-points. This defines the default broadcastdomain boundary.• Logical Router — A tenant router providing routing andpolicy enforcement services for inter-segment, inter-tenant, and external networks.• External Core Router — A physical router that providesconnectivity between Pods within a data center and to the Internet.• Tenant Services — Services available to tenants anddeployed as dedicated or shared services (individually or as part of a service chain).Figure 4: CCF Graphical User Interface (GUI)E-VPC (Tenant)In the most common scenario, end consumers or tenantsof the data center infrastructure deal with a logical network topology that defines the connectivity and policy requirements of applications. As an illustrative example, the canonical 3-tier application in Figure 5 shows various workload nodes of a tenant named “BLUE.” Typically, a tenant provisions these workloads using orchestration software such as OpenStack, VMware vSphere, or CCF Controller GUI/CLI, directly. As partof that provisioning workflow, the CCF Controller seamlessly enables the logical topology onto the physical and virtual switches.Mapping Logical to PhysicalThe BLUE Tenant has three logical network segments. Each of the three segments represents the broadcast domain for the3-tiers—Web, App, and Database. Let’s say in this example, Web1,2 and App1,2 are virtualized workloads but DB1,2 is comprised of physical workloads. Following the rules defined by the data center administrator, the orchestration system provisions requested workloads across different physical nodes within the data center. As an example, the logical topology shown in Figure 5 could be mapped on the pod network.The CCF Controller handles the task of providing optimal connectivity, between these loads dispersed across the pod, while ensuring tenant separation and security.In order to simplify the example, we only show racks that host virtualized and physical workloads in the figure above, but similar concepts apply for implementing tenant connectivity to external router and chaining shared services.An illustrative sample set of entries in various forwarding tables highlight some of the salient features of CCF described in earlier sections.• L3 routing decision is made at the first hop leaf switch(distributed virtual routing—no hair-pinning)• L2 forwarding across the pod without special fabricencapsulation (no tunneling)• Full load-balancing across the various LAG links (leaf andspines)• Leaf/Spine mesh connectivity within the physical fabric for resilienceFigure 5: CCF Logical TopologyFigure 6: Application Centric ConfigurationFeatureCCF Controller Appliance SpecificationThe CCF Controller can be deployed either as a physical appliance (production or lab deployment) or as a virtual machine appliance (for limited scale production or lab deployment).CCF Controller — Physical Appliance Specification:The CCF controller is available as an enterprise-class, 2-sockets, 1U rack-mount physical appliance designed to deliver the right combination of performance, redundancy and value in a dense chassis.* Detailed environment information provided in CCF Hardware Guide.Arista CCF Controller: DCA-CC-CDLVM Appliance SpecificationThe Converged Cloud Fabric Controller VM Small is available as a Virtual Machine appliance for P or P+V fabric (for limited scale production or lab deployment).Note: A VM’s performance depends on many other factors in the hypervisor setup, and as such, we recommend using a hardware appliance for production deployments greater than three racks.Supported Workloads & Orchestration SystemsSanta Clara—Corporate Headquarters 5453 Great America Parkway, Santa Clara, CA 95054Phone: +1-408-547-5500 Fax: +1-408-538-8920 Email:***************Copyright © 2023 Arista Networks, Inc.

数据价值的重塑

数据价值的重塑作者：丁海骜来源：《数字商业时代》2021年第12期“目前我们正处在一个数字化时代当中，一切皆数据。

因此对于企业级用户而言，对于数据管理，都面临着扩展、整合、支持多云等多方面的需求。

”2021年11月16日，Commvault 宣布在中国推出Commvault HyperScale X高性能集群架构一体机。

Commvault中国区总裁刘玮在接受采访时强调：推出全新一体机的初衷，完全是为了满足企业用户的需求：“虽然我们也能看到目前市场上有一些所谓的备份一体机，但企业对于数据管理的需求，已经超出了这些传统产品的能力范畴——这些传统产品更多还仅仅是着眼于一些比较分割的一些需求，如比较标准化且中小型企業的需求——对于扩展、整合、支持多云的支持，难以实现。

”事实上在2019年以前，Commvault也面临同样的问题。

了解Commvault的人都知道，Commvault HyperScale技术实际上是Commvault四大当家产品之一，本质上是Commvault备份的一项扩展技术，用以为用户交付本地类云基础架构，以支持其可扩展的二级存储。

但是其中始终有一个问题：虽然用户可以通过采用Commvault HyperScale一体机或者部署软件解决方案的方式，在使用者和各种不同的云之间搭建一个虚拟化的数据管理层，实现对企业全部数据的备份和恢复。

但随着企业IT基础架构越来越明显地呈现出多云应用、混合云、容器化的趋势后，受虚拟化技术自身能力的限制，Commvault HyperScale也会时常受到挑战：如何以更低的成本管理被存储在不同环境中的数据，成为其急需解决的一个问题。

2019年9月，刚刚到任Commvault首席执行官的Sanjay Mirchandani，斥资2.25亿美元收购了软件定义存储（SDS）初创公司Hedvig——Hedvig软件最大的价值，在于能够通过单一平台实现对跨越不同物理位置（包括不同的云环境）的多个数据中心的本地化管理。

HyperScale系统中容器存储子系统的设计与实现

HyperScale系统中容器存储子系统的设计与实现随着IT技术的不断发展,各行业面对数据量的猛烈增长,能够同时满足高速计算和海量存储的数据中心在各个领域中的作用变得越来越重要。

IBM公司便提出了自己的Hyper Scale系统,将计算资源和存储资源进行整合,同时在系统底层使用了容器技术。

Hyper Scale系统中负责计算工作的部分是ASC模块,分布式架构的底层使用了Docker容器,容器管理方面使用了Kubernetes编排工具;Hyper Scale系统中负责存储工作的部分为容器存储子系统,在传统的容器存储解决方案中,容器通常使用的是临时存储,经常会导致容器消失后,容器中的数据也随之消失,基于此给底层使用容器技术的大型系统提供拥有持久化存储的容器就是必不可少的。

同时,OpenStack中的Cinder组件从设计之初就是帮助系统管理块存储资源的,因此容器通过与Cinder组件进行整合来实现持久化存储也是符合行业需求的。

本文中首先对研究人员在开发过程中发现的问题和用户在使用产品时遇到的困难进行充分调研,发现了现阶段很多种面向容器的资源存储方案都存在无法持久化存储的现象,与容器绑定的存储资源生命周期与系统中容器的生命周期息息相关,容器被停止甚至删除以后,极易导致原来与容器绑定的存储卷内的数据一并消失,造成无法挽回的损失。

在查阅大量国内外资料和公司文档后,本文对Hyper Scale系统中容器存储子系统在不同业务应用场景中的情况进行了详细的需求分析。

在需求分析的基础上,本文仔细研究了IBM公司Hyper Scale系统的架构和各部分功能,进而分别详细描述了系统中的应用架构和功能结构,并基于此设计了帮助系统中的容器使用持久化存储资源的容器存储子系统。

实现过程中,在目前行业内OpenStack与容器技术兼容性不断提高的背景下,提出了利用Cinder组件自身对块存储资源进行管理的特点,使容器存储与Cinder组件进行整合的技术。
