Opis: VMware VSphere 5 Building a Virtual Datacenter - Eric Maille, Rene-Francois Mennecier

Every year, datacenter managers must deliver more services faster, with greater flexibility. They must efficiently handle soaring amounts of data, and unprecedented levels of complexity. And they must do all this with lower budgets and fewer resources. Datacenter virtualization with VMware's vSphere(R) 5 is the best way to achieve these goals and to accelerate your transition to cloud services. VMware vSphere(R) 5: Building a Virtual Datacenter brings together all the practical knowledge you need to evaluate, plan, implement, and manage vSphere 5 in your datacenter environment. Top datacenter virtualization consultants Eric Maille and Rene-Francois Mennecier begin by introducing vSphere 5 from the viewpoint of the datacenter manager and professional. They present essential definitions, advantages, and functions; review vSphere 5's architecture; and introduce core components such as vCenter Server and ESXi 5.0. Next, Maille and Mennecier turn to implementation, presenting detailed examples, schemas, and best practices drawn from their extensive experience. They share practical insights into budgeting, scheduling, and planning; choosing the right architecture; and integrating vSphere with existing datacenter elements, including servers, storage, clusters, network infrastructure, and business continuity plans. They conclude with a start-to-finish case study: a datacenter virtualization project designed to support specific business objectives. Coverage includes * Assessing the potential benefits of datacenter virtualization in your environment * Organizing and managing a smooth migration to the virtualized datacenter * Anticipating specific challenges and risks associated with datacenter virtualization * Making tradeoffs to optimize stability, elasticity, scalability, and cost * Choosing the best installation/configuration options for your environment * Effectively linking vSphere 5 virtualization to existing datacenter elements * Driving more value from vSphere 5's powerful new datacenter features * Providing storage to efficiently support your hosted VMs, now and in the future * Managing limited memory and other server constraints * Leveraging new options for service continuity and high availability * Using backup architecture as a lever to reduce costsAcknowledgments xvi Foreword xviii Preface xx 1 From Server Virtualization to Cloud Computing 1 Virtualization: The Heart of IT Transformation 1 Server Virtualization 2 Server Virtualization Adoption Factors 2 Specifications for a Virtualized Environment 4 Benefits of Virtualization 6 Phases of Virtualization 8 Phase 1: IT Rationalization 9 Phase 2: Critical Applications 10 Phase 3: Automation 13 Virtualization Ecosystem 15 Server Virtualization 15 Desktop Virtualization 16 The Future Looks Bright 20 2 The Evolution of vSphere 5 and Its Architectural Components 21 VMware Overview 21 VMware Portfolio 21 VMware Evolution 22 vSphere 5 Licenses 27 vSphere 5 Versions 27 Licensing Model 29 vCenter Server 5.0 Licenses 30 What's New in vSphere 5?
