advantage of VMware Server

VMware Server是免费的,它的前身为VMware GSX。但Virtual Center for VMware Server不是免费的,它的计费方式为VMware Server(1个), 以及VMware Server host agent(n个).
VMware Server支持32/64为操作系统,支持最多2 vSMP的VM. 只支持1个快照,不支持录像功能。支持template. 他的template既可以放在host中,也可以放在VC Server.还支持在Host之间的cold migration, 这些功能显然需要VC的支持。
VMware Virtual Center有两个版本,1.4.1是专门为Virtual Server设计的,和以前ESX2.5.x的比较类似,而VC2.0.x是专为ESX设计的。
和workstation相比,VMware Server更注重集中统一管理和监控。但从具体的功能而言,不如Workstation.VMware Server中有VM Importer, 但不象Workstation, 还有converter.

  1. Q: How is VMware Server different from Workstation? Will Workstation also be free?

    A: VMware will continue to charge for Workstation and has no plans to drop its price. Workstation has unique, advanced features that are not available in VMware Server. These features include the ability to manage multi-tier configurations and multiple snapshots. Workstation is a productivity tool used by developers and technical professionals on an individual PC. VMware will continue to develop compelling features on this product that dramatically streamline software testing and development.

  2. Q: What is VMware Infrastructure? How is VMware Server different from VMware Infrastructure?

    A: VMware Infrastructure allows entire industry-standard infrastructure farms to be managed as a shared utility and dynamically allocated to different business units or projects. Delivering built-in management, resource optimization, application availability and operational automation capabilities, VMware® Infrastructure 3 dramatically reduces costs and increases efficiency, flexibility and IT service levels. Users of VMware Server can protect their investment if they choose to migrate to VMware Infrastructure as VMware virtual machines are fully compatible across the product line.

  3. Q: How does VMware Server work?

    A: VMware Server installs and runs as an application on top of a host Windows or Linux operating system. A thin virtualization layer partitions the physical server so multiple virtual machines can run simultaneously on a single server. Computing resources of the physical server are treated as a uniform pool of resources that can be allocated to virtual machines in a controlled manner. VMware Server isolates each virtual machine from its host and other virtual machines, leaving them unaffected if an application in a virtual machine crashes. Data does not leak across virtual machines and applications can only communicate over pre-configured network connections. VMware Server encapsulates a virtual machine environment as a file, which is easy to back-up, move and copy.

  4. Q: When will VMware Server be available?

    A: VMware Server is available immediately.

  5. Q: Where can I download VMware Server?
