describes the high-level design of the Vscale Architecture.</p><p>Vscale Architecture is an architectural framework that uses Vscale Fabric to connect modular buildingblocks such as Converged Systems and Vscale Fabric Technology Extensions. This provides VscaleArchitecture the flexibility to accommodate a wide variety of application requirements using an ITinfrastructure that can scale from a single Converged System to the largest data center.</p><p>The target audience for this document includes sales engineers, field consultants, advanced servicesspecialists, and customers.</p><p>The following table provides a description of related documentation:</p><p>Document Provides</p><p>Release Certification Matrix A list of the certified versions of software, firmware, and hardware.</p><p>Converged Systems Physical Planning Guide A description of the physical components and elevations.</p><p>Converged Systems Powering On and OffGuide</p><p>Instructions on how to manage power.</p><p>Integrated Data ProtectionGuide Contains information on advanced planning and backup guidelines.</p><p>Release Certification Matrix A list of the certified versions of software, firmware, and hardware.</p><p>Vision Intelligent Operations AdministrationGuide</p><p>Information on how to manage Converged Systems.</p><p>Glossary Definitions of terms specific to Converged Systems.</p><p>Introduction | 4</p><p>https://docs.vce.com/bundle/O_GLOSSARY/page/GUID-E5B5E1DA-8455-460A-8391-12F5783BE2A3.html</p></li><li><p>Architecture overviewVscale Architecture is a framework that enables the building of data-center scale IT systems comprised ofresources logically connected using a Vscale Fabric to form logical systems.</p><p>The Vscale Architecture modular building blocks include the following:</p><p> New or existing Converged Systems (Vblock Systems, VxBlock Systems, or VxRack Systems).</p><p> Converged Systems that can be expanded with Converged Technology Extensions.</p><p> Vscale Fabric delivers scalable LAN and SAN switching for connectivity between Vscale FabricTechnology Extensions and Converged Systems.</p><p> Vscale Fabric incorporates a scalable spine/leaf LAN architecture with optional software-defined networking (SDN) and a core/edge SAN architecture.</p><p> Vscale Fabric Technology Extensions are modular containers that provide connectivity forcompute, storage, and data protection resources consumed by other resources attached tothe Vscale Fabric.</p><p> TheVscale Border Technology Connect provides external intranet and internet connectivity forexternal facing routers, firewalls, and other edge functions to communicate with the VscaleArchitecture.</p><p> The Vscale Open Technology Connect enables an organization to integrate non-Dell EMCresources into the Vscale Architecture to provide investment protection and flexibility.</p><p> Vscale Management Platform is a scalable management platform that hosts core managementapplications, which can also be extended to support an IT organization's management andorchestration stacks, as well as other applications, such as logging and SEIM.</p><p>By connecting multiple modular components to a scalable network fabric, a wide variety of applicationrequirements at any scale can be accommodated. Vscale Architecture offers a high degree of flexibilityand scale that compliments Converged Systems with the following benefits:</p><p> Dell EMC engineered and validated architecture.</p><p> Dell EMC lifecycle management and support.</p><p> Dell EMC Release Certification Matrix (RCM) certification for all Dell EMC-provided componentsincluding LAN and SAN fabrics.</p><p> Uplinks to Vscale Fabric for unified storage access and file services.</p><p> Out-of-band management networks.</p><p> VMP as a scalable platform used to host Converged Systems element managers for allinfrastructure components in the data center. VMP can be extended to support Dell EMCecosystem management workloads and other management applications.</p><p> Logical build guidelines that include prescriptive connectivity and management.</p><p> Vision Intelligent Operations software for managing the health, Dell EMC RCM and securitycompliance of Converged Systems across the Vscale Architecture.</p><p>5 | Architecture overview</p></li><li><p>The following illustration shows how Vscale Architecture combines the modular components:</p><p>Vscale Fabric</p><p>Vscale Fabric consists of two discrete, switched LAN and SAN networks. The Vscale LAN Fabric containsspine and leaf switches that provide Ethernet and IP connectivity. The spine switches are high-throughputswitches that forward traffic between the leaf switches. The leaf switches provide a network connectionpoint for resources in the Vscale Fabric Technology Extensions and Converged Systems to connect tothe spine switches.</p><p>Architecture overview | 6</p></li><li><p>The following illustration shows a Vscale LAN Fabric where the spine, leaf, and Vscale Fabric TechnologyExtensions connect:</p><p>The Vscale SAN Fabric is a flexible, core-edge or edge-core-edge architecture that uses FC SANswitches for storage connectivity. The core switches are high throughput, director-class switches with highport density that provide connectivity for storage arrays and edge switches. The edge switches provide aSAN connection point for compute and storage resources in Vscale Fabric Technology Extensions andConverged Systems.</p><p>7 | Architecture overview</p></li><li><p>The following illustration shows how the SAN core and Vscale Fabric Technology Extensions connect:</p><p>Vscale Fabric Technology Extensions</p><p>Vscale Fabric Technology Extensions are modular containers that connect Dell EMC compute, storage,and data protection resources to the Vscale Fabric. These resources can be logically configured to formlogical systems or consumed by other systems attached to the Vscale Fabric.</p><p>Vscale Fabric Technology Extensions contain the following components:</p><p> Intelligent physical infrastructure is a 42 RU enclosure that includes an intelligent gateway thatgathers information about power, thermals, security, alerts, and all components in the physicalcabinet.</p><p> Two LAN leaf switches (optional if LAN connectivity is not required).</p><p> Two SAN edge switches (optional if SAN connectivity is not required).</p><p> One or more Dell EMC management switches.</p><p>Vscale Fabric Technology Extensions can be populated with storage, compute or data protectionresources, or a combination of resources to meet a particular operational model or application use cases.</p><p>Architecture overview | 8</p></li><li><p>For example, a Vscale Fabric Technology Extension can be configured with storage or compute only orwith both storage and data protection resources.</p><p>Technology connects</p><p>The is a special use case of Vscale Fabric Technology Extensions that can include resource types thatDell EMC does not support. The is used solely for non-Dell EMC, third-party resources that provideconnectivity for non-Dell EMC supplied, third-party IT infrastructure. The includes compute servers,storage, or data protection resources and provides VXLAN connectivity.</p><p>An can be populated with any third-party, non-Dell EMC supplied assets. This enables organizations tointegrate technology assets that have not been depreciated, or have strategic value, but cannot be re-platformed to x86 technology. An cannot be used for Dell EMC-provided systems or resources.</p><p>The contains the following components:</p><p> Intelligent physical infrastructure</p><p> Two LAN leaf switches</p><p> Two SAN edge switches</p><p> One or more Dell EMC management switches</p><p>The contains similar components as the but is used to provide external connectivity for customer routers,and other edge devices such as firewalls, application delivery controllers, or intrusion detection protection.SAN edge switches are not required for a border technology connect.</p><p>Management</p><p>Vscale Management Platform is used to manage all components in a Vscale Architecture deployment.VMP is a scalable management platform that hosts core Dell EMC management workloads such aselement managers, VMware vCenter Servers, and Secure Remote Support.
