什么是VirtualCenter
VirtualCenter是一套虚拟架构的管理软件，仿佛一个逻辑的虚拟机池，它中心管理企业内部的虚拟机资源。通过VirtualCenter，管理员能够单点管理上千台Windows
NT/2000/2003/Linux/Netware服务器。VirtualCenter接口提供了一个强大的浏览功能，能够浏览数据中心的所有虚拟资源。通过VirtualCenter接口，管理员能够完成：
流量整合 通过调整每个软件服务器占用的资源，监视和最优化数据中心资源的使用，在维护应用服务服务的级别上，最小化资源的浪费。
即时准备
把服务准备时间从几星期缩短到几十秒，从而允许管理员最快的响应IT服务需求。通过使用服务器模板，管理员能够确保新的服务器在网络结构和安全策略上和现有的服务器完全兼容。
零维护时间
7天24小时的不间断的硬件维护、部署和迁移服务。使用VMotion将正在运行的操作系统和应用程序从需要维护的系统中迁移，并于维护结束后将操作系统及应用程序迁回。
VMotion技术的突破
VMotion技术可以将活动的虚拟机从一个物理系统移动到另
一个物理系统，而不间断服务。VMotion还允许快速的重新配置
和优化虚拟构架中的资源。
VirtualCenter 能做什么
VirtualCenter管理虚拟计算机和存储、服务器和网络资源，
它使整个数据中心看起来像一个完整的工作环境或者是一个
虚拟架构的共享资源。 VirtualCenter 提供了对虚拟架构中
资源计划和使用的全局总揽。请思考下面的问题，如果你对
每一个问题的答案都是“是的”，那么VirtualCenter就能给
你的组织带来重大的利益。
你将从8点到5点的不打扰用户的系统维护中受益吗？
你需要在你的IT构架和快速响应过程中快速的鉴定问题吗？
你不得不管理一打儿虚拟机吗？
你在准备新的计算机和应用程序资源时需要不间断作业吗？
当需求增长时，为了争取SLA响应时间，你是否需要超时工作？
你需要在缩减投入和成本时增加系统性能吗？
VirtualCenter 带来的好处
管理分散的不同种类的计算机环境，使他们看上去好象一个独立的硬件资源池。
在不影响用户的情况下改变服务器配置或进行硬件维护。
创建用户定义的自动化的邮件警告和动作，缩短响应时间。
高效率的完成自动化的系统准备和服务器部署任务。
通过部署基于模板的服务器增加连续性。
动态管理访问分布式的物理服务器的流量，是性能达到最优化。
和现有的管理和监视系统集成。
What Is VMware VirtualCenter?
VMware VirtualCenter is virtual infrastructure management software, providing a central point of control for your data center's virtual computing resources.
虚拟架构管理软件，一个控制数据中心的虚拟计算资源的集中点
VirtualCenter creates a more responsive data center, which enables faster reconfiguration and reallocation of applications and services. It allows instant provisioning of servers. User-downtime is decreased. The data center becomes optimized. VirtualCenter is a powerful way to connect IT to business needs.
快速的 应用和服务的 重新配置 和 重分配
With VirtualCenter, IT infrastructure becomes more flexible, efficient and responsive. VirtualCenter uniquely leverages virtual computing, storage and networking to improve data center management and reduce cost.

How is VMware VirtualCenter Used?
VirtualCenter is for businesses that want to build cost-effective utility computing environments and optimized data centers. It allows them to instantly provision servers, globally manage resources and eliminate scheduled downtime for hardware maintenance.
"VMware VirtualCenter is one of the few tools in my solution stack that actually performs as the vendor promised. VirtualCenter combined with ESX Server and VMotion technology™ is the first set of products I抳e seen that allows me to easily manage workloads across multiple systems without requiring a major investment in staff or training."
-- Eric Kuzmack, IT Architect, Gannett Co., Inc.
VirtualCenter reduces time, effort and complexity of data center management by:
Optimizing the data center and enabling utility computing services
Leveraging industry standard x86-architecture hardware
Unifying management of diverse environments including Microsoft Windows, Linux and Novell operating systems.
IT organizations use VirtualCenter to improve data center architecture. Large-scale IT initiatives benefit from the responsiveness, ease-of-change and integration that VirtualCenter provides.
VirtualCenter enables dramatic improvements in:
Server Consolidation: Contain server sprawl while consolidating heterogeneous server applications, such as Exchange, Notes, SQL Server, Oracle, WebSphere, BEA, SAP, Siebel, Citrix, Active Directory as well as legacy applications.
Resource Management: Allocate resources based on business demand. Dynamically re-map resources to software for better responsiveness and efficiency.
Disaster Recovery: Simplify deployment of critical systems and applications to recovery site(s).
How Does VMware VirtualCenter Work?
VirtualCenter centrally manages ESX Server and GSX Server Virtual Infrastructure Nodes (VIN) as a single, logical pool of resources. VMware GSX Server VINs are comprised of GSX Server and a VirtualCenter Agent. VMware ESX Server VINs are comprised of ESX Server, VMware Virtual SMP, VMotion?and a VirtualCenter Agent. Key management functions built-in to VirtualCenter include:
VirtualCenter reduces time, effort and complexity of data center management by:
A single view, or "dashboard" of all virtual machines
Monitoring of system availability and performance
Automated notifications with email alerting
Robust access control integrated with Windows authentication
VirtualCenter runs as a service on Windows 2000, Windows XP Professional and Windows 2003. VirtualCenter works with the existing hardware and software infrastructure, including blade servers and 1-U rack-mount servers (between 2-16 CPUs per server). VirtualCenter manages any x86-based computing platform.
Key Features
VirtualCenter managed ESX Server and GSX Server VINs enable centralized and secure management of the VMware virtual infrastructure. Features include:
Centralized Virtual Infrastructure Management Console: Manage hundreds of virtual machines from one location through robust access controls. Monitor system availability and performance. Configure automated notifications and email alerts.
Instant Provisioning Deployment Wizard: In minutes, deploy new servers using a template-based deployment wizard. VirtualCenter takes advantage of the uniformity of virtual hardware to make instant provisioning possible.
Virtual Infrastructure SDK: Closely integrate 3rd-party management software with VirtualCenter through the Virtual Infrastructure SDK, to seamlessly integrate existing solutions with the VMware virtual infrastructure.
With VMotion live servers can be moved from one virtual machine host to another. IT organizations can provide zero-downtime maintenance and continuous workload consolidation without impacting user services.
VMotion and the ESX Server Infrastructure Node:
VMware ESX Server VINs include VMotion technology that enables intelligent workload management. VMotion allows changes to be made on the fly without impacting users, thus providing rapid reconfiguration and optimization of resources across the virtual infrastructure. VirtualCenter managed ESX Server VINs provide a means to respond to data center needs. Including:
Migrating a running virtual machine to a different physical server connected to the same storage area network (SAN) without service interruption.
Performing zero-downtime maintenance by moving virtual machines around so the underlying hardware and storage can be serviced without disrupting user sessions.
Continuously balancing workloads across the data center to most effectively utilize resources in response to changing business demands.
