    Executive summary

    The Dell EMC™ XC Series Web-Scale Hyperconverged appliance powered by Nutanix™ delivers a highly

    resilient, converged compute and storage platform that brings benefits of web-scale architecture to business-

    critical enterprise applications such as Oracle®.

    The XC Series platform is hypervisor agnostic and software installs quickly for deployment of multiple

    virtualized workloads. The XC Series Nutanix platform can deliver storage through multiple protocols such as

    NFS, SMB, and iSCSI.

    This document provides guidelines for design, configuration, and optimization of Oracle single instance and

    Real Application Cluster (RAC) databases applications running on XC Series Nutanix infrastructure. The

    document also outlines the different storage presentation methods offered by Nutanix to deploy the Oracle

    database application.

    1 Product overview

    1.1 XC Series appliances The XC Series is a hyperconverged solution that combines storage, compute, networking, and virtualization

    into an industry-proven x86 Dell EMC PowerEdge™ server running Nutanix web-scale software. By

    combining the hardware resources from each server node into a shared-everything model for simplified

    operations, improved agility, and greater flexibility, Dell EMC and Nutanix together deliver simple, cost-

    effective solutions for enterprise workloads. Acropolis Distributed Storage Fabric (DSF) delivers a unified pool

    of storage from all nodes across the cluster, using techniques including striping, replication, autotiering, error

    detection, failover, and automatic recovery.

    The XC Series infrastructure is a scale-out cluster of high-performance nodes, or servers, each running a

    standard hypervisor and containing processors, memory, and local storage (consisting of SSD flas
