The drive toward convergence La transition vers la convergence

Previous IT waves A new computing landscape requires a new architecture Virtualization 2010s Client/server 1990s and 2000s Mainframes/minis 1970s and 80s

What is driving convergence? 80% 68% 25X 80% Cloud 80% of cloud initiatives will be private and hybrid Data center traffic 25X more bandwidth (I/O) per rack needed Operating costs In 2012, 68% of server-related spend was on management2 Virtualization 80% server virtualization by 20164

La convergence peut y remédier Les clients nous disent que dans l’ère moderne, l’infrastructure informatique existante crée des défis Coûts élevés de la gestion du datacenter Pas assez de personnel compétent Déploiement des charges de travail chronophage et difficile Difficulté de préservation de l’homogénéité La convergence peut y remédier Déploiement des charges de travail à travers plusieurs environnements Complexité croissante Flexibilité synonyme d’augmentation des coûts et de compromis sur les performances Manque de choix

Customers tell us: Legacy IT in the modern era creates challenges High costs of data center management Not enough skilled staff Deploying workloads is time-consuming and difficult Difficult to ensure consistency Convergence can help Workload deployment crosses multiple environments Rising complexity Flexibility comes with price and performance compromise Lack of choice Coûts élevés de la gestion du datacenter Difficulté de préservation de l’homogénéité Complexité croissante Pas assez de personnel compétent Flexibilité synonyme d’augmentation des coûts et de compromis sur les performances Déploiement des charges de travail chronophage et difficile Déploiement des charges de travail Manque de choix à travers plusieurs environnements

Qu’est-ce que la convergence ? combinaison d’au moins deux éléments informatiques distincts Gestion unifiée Infrastructure convergée Solutions hyperconvergées Gestion multiplateforme à partir d’une seule console, permettant de contrôler tous les composants de l’infrastructure via une seule interface en utilisant un framework commun de contrôle et de gestion Système certifié préintégré contenant le matériel serveur, les systèmes de stockage sur disque, l’équipement réseau et le logiciel de gestion unifiée Système d’infrastructure optimisé pour les charges de travail, reposant sur une architecture qui intègre étroitement les ressources de traitement, de stockage, de réseau et de virtualisation dans une solution unique

Convergence and the path to modernization Datacenters are changing – Legacy IT is siloed and cannot deliver cloud-scale IT The move to Software Defined IT requires disruption of the traditional approach Modern workloads such as big data are breaking down barriers between IT silos IT users expect faster, cloud like service from their datacenters Hyper-Converged: Converged stacks optimized for workloads Converged Platforms: Pre- integrated server, storage and networking Unified Management: Integrated Datacenter management Private cloud: Optimized service-centric data center Traditional data center: Disparate hardware from different vendors Converged Infrastructure Les clients nous disent que dans l’ère moderne, l’infrastructure informatique existante crée des défis Les datacenters sont en train de changer : l’infrastructure existante est cloisonnée et ne permet pas de fournir des services informatiques à l’échelle du Cloud. La transition vers l’informatique Software Defined exige de transformer l’approche traditionnelle. Les charges de travail modernes comme le Big Data obligent à éliminer les cloisons entre les silos informatiques. Les utilisateurs finaux veulent que leurs datacenters leur fournissent un service de type Cloud, plus rapide

The combination of two or more separate IT elements Convergence Defined! Convergence: The combination of two or more separate IT elements Unified management Converged infrastructure Hyper-converged Cross platform management from a single console, enabling all infrastructure components to be managed though a single interface utilizing a common management and control framework A pre-integrated, certified system containing server hardware, disk storage systems, networking equipment and unified management software A workload-optimized infrastructure system built on an architecture that tightly integrates compute, storage, networking and virtualization resources in a single box

A new approach Infrastructure Traditionnelle Infrastructure Convergée Web-Scale Serveur Stockage Totalement logiciel… Haute performance Mise à l’échelle linéaire VM-centric Key Points: Native convergence (or hyper-convergence) is critical in the modern datacenter Traditional three-tier architecture has scale-out compute (with virtualization) connected to scale-up storage The storage network adds latency and becomes a bottleneck, especially as flash storage becomes more prevalent in all storage systems Data has to be retrieved from storage every time some operation needs to be done in the server. This north-south traffic kills performance because it does not respect data gravity Deploying and scaling out storage is complex and error-prone Storage is managed in terms of LUNs and RAID sets, while Hyperviseurs talk about vdisks – different granularity Admins have to set up port bonding, multipathing, I/O mapping etc. to deploy the network Nutanix eliminates the complexity and bottleneck of the storage network and delivers a converged solution for virtual environments that can be scale out on demand

A change agent from day one A leading provider of end-to-end solutions A strategy recognized by customers of all sizes across all industries Simplifying the complex Making the powerful easy to use Driving out inefficiency Delivering superior long-term value Giving you the power to do more DELL HAS DISRUPTED THE MARKET FROM THE BEGINNING: Dell has been an agent of change since Michael Dell began building and selling computers out of his dorm room at the University of Texas in 1984. Very quickly we revolutionized the PC industry. And along the way we grew into much more than a PC company. Today, we are a full-fledged provider of end-to-end technology solutions that span the desktop to the data center and to the cloud. WE’RE A PRIVATELY HELD COMPANY AGAIN: We are free to fully realize our flexible, end-to-end solutions strategy. And we have the opportunity to more rapidly pursue organic and inorganic investments without the scrutiny of public investors or the pressure to reach short-term targets. We see ourselves as the world’s largest startup. We are getting back to our roots, unleashing the entrepreneurial spirit that made Dell one of the fastest growing, most successful companies in history. But unlike many startups, Dell has a strong balance sheet and solid cash flow. We’re unleashing the creativity and confidence that have always been the hallmarks of our culture. We will be able to serve our customers with a single-minded purpose and drive the innovations that will change our world for the better, advancing Michael’s bold vision to transform the IT industry by making the best technology accessible to more people. WE’RE WE’VE GROWN: We're dramatically different today. After nearly 30 years of existence Dell is a fundamentally different company that it was in the beginning, and very different than it was just a few years ago. Today, we are one of the most recognized brands in the world. We serve: 95% of global Fortune 500 10 million small businesses 400,000 classrooms Every G20 government 200,000 physicians 140,000 channel partners 60,000 retail locations Our reach includes: More than 100,000 team members 65% of Dell team dedicated to servers, storage, networking and services 8,000 team members in China 27,000 team members in India 22 solutions centers in 2012 R&D centers in Israel, Silicon Valley and Austin 120,000+ Dell systems shipped each day; more than 1 every second DESPITE THE RECENT CHANGES, ONE THING REMAINS THE SAME: Our purpose. We deliver technology solutions that enable people everywhere to grow and thrive and reach their full potential. To achieve this: We simplify the complex We make the powerful easy to use We drive out inefficiency We deliver superior long-term value THIS APPROACH PUTS OUR CUSTOMERS FIRST: Our purpose is to enable yours, and give you the power to do more.
