2Technology overviewThis reference architecture conveys deployment integration points of Pivotal Cloud Foundry on Dell EMC XCSeries Hyper-converged appliances.2.1Dell EMC XC Series Hyper-converged appliancesThe Dell EMC XC Series hyper-converged appliances are a hyper-converged solution that combines storage,compute, networking, and virtualization into an industry-proven appliance base on an x86 Dell PowerEdge server running Nutanix software. By combining the hardware resources from each server appliance into ashared-everything model for simplified operations, improved agility, and greater flexibility, Dell EMC andNutanix together deliver simple, cost-effective solutions for enterprise workloads. Nutanix Distributed StorageFabric (DSF) delivers a unified pool of storage from all appliances across the cluster, using techniquesincluding striping, replication, auto-tiering, error detection, failover, and automatic recovery.The XC Series infrastructure is a scalable cluster of high-performance appliances, or servers, each running astandard hypervisor and containing processors, memory, and local storage (consisting of solid state disk(SSD) flash for high performance and high-capacity SATA disk drives). Each appliance runs virtual machinesjust like a standard hypervisor host as displayed in Figure 1.Nutanix appliance architecture8Production Pivotal Cloud Foundry on Dell EMC XC Series Hyper-Converged Appliances Reference Architecture 000032 A00
2.1.1Nutanix architectureNutanix software provides a hyper-converged platform that uses DSF to share and present local storage to allthe virtual machines in the cluster. The general Nutanix architecture is shown in Figure 2.Nutanix architectureDSF virtualizes the storage across all appliances and presents the same to the hypervisor as one large poolof shared storage. The DSF replicates writes synchronously to at least one other XC Series appliance toensure cluster resiliency and availability. Local storage for each XC Series appliance in the architecture ispresented as one large pool of shared storage to hypervisor.In addition, DSF virtualizes local storage from all appliances into a unified pool. DSF uses local SSDs anddisks from all appliances to store virtual machine data. Virtual machines running on the cluster write data toDSF as if they were writing to shared storage.XC Series offers customer choice of hypervisors without being locked-in. The hypervisors covered in thisreference architecture are: VMware ESXi In addition, the solution includes the Nutanix Controller VM (CVM), which runs the Nutanix software andserves I/O operations for the hypervisor and all VMs running on that host. Each CVM connects directly to thelocal storage controller and its associated disks thereby reducing the storage I/O latency. The data localityfeature ensures virtual machine I/O is served by the local CVM on the same hypervisor appliance, improvingthe VM I/O performance regardless of where it runs.9Production Pivotal Cloud Foundry on Dell EMC XC Series Hyper-Converged Appliances Reference Architecture 000032 A00
2.2Pivotal Cloud Foundry architecturePivotal Cloud Foundry provides an enterprise-ready Cloud Native platform that abstracts virtualizedcompute/storage/network resources and software stacks into an application platform especially well-suited torun modern micro-services based applications.Pivotal Cloud Foundry (PCF) is a commercial version of Cloud Foundry Platform as a Service (PaaS) thatsupplies developers with a ready-to-use cloud computing environment with application services.All of the application services are hosted by virtualized servers on existing on-premises (private) or offpremises (public) infrastructure.PCF is a structured cloud-native platform that is made up of standardized components and enablesdevelopers with a rich set of services for deploying, scaling and managing the application lifecycles.PCF enables operator visibility and control to manage the platform. The base PCF functionality that wedeployed in this RA offers the following features: 10Ops ManagerApplication deployment and managementPolyglot (frameworks, languages, and services)Container managementUser management with role based accessPerformance monitoring and reportingCentralized log aggregationSecurityFault tolerance and multiple resilience levelsProduction Pivotal Cloud Foundry on Dell EMC XC Series Hyper-Converged Appliances Reference Architecture 000032 A00
3Solution reference architectureBy combining Pivotal Cloud Foundry with XC Series in a VMware vSphere environment, enterprises canpainlessly create a full-featured, tightly integrated cloud platform based on open technologies.The solution used for this RA was an on-premises (private) infrastructure that reflected the deployment ofPCF and promotion of applications onto PCF. The underlying infrastructure was based on the Dell EMCXC630-10 appliance.See Appendix A for details on the hardware and software configurations.Figure 3 shows the PCF stack deployed on an ESXi hypervisor that is associated with a multi-TB container.Dell EMC XC Series hyper-converged appliances with PCF overview.XC Series and PCF are designed for maximum availability. They offer zero downtime upgrades to bothplatform and applications. PCF enables developers to code in multiple languages and frameworks. PCF offersa cloud computing environment for application developed services, all hosted on a scalable XC Series.3.1Network configurationFigure 4 shows the network topology and interconnects used for this solution in a single cluster. This solutionuses Dell Networking S4048-ON switches.Figure 5 shows the network topology and interconnects used for this solution at a higher level for all threeclusters.Dell EMC recommends a minimum of two 10 GbE interfaces for each host. Each host should connect toredundant switches for network path redundancy.11Production Pivotal Cloud Foundry on Dell EMC XC Series Hyper-Converged Appliances Reference Architecture 000032 A00
