VMware VCENTER SERVER 4.0 - GETTING STARTED UPDATE 1 Bedienungsanleitung PDF herunterladen (Seite 18)

vCenter Server allows the use of advanced vSphere features such as VMware

Distributed Resource Scheduler (DRS), VMware High Availability (HA), and

VMware VMotion.

Datacenter

A datacenter is a structure under which you add hosts and their associated

virtual machines to the inventory.

Virtual Machine

A virtual machine is a software computer that, like a physical computer, runs

an operating system and applications. Multiple virtual machines can run on

the same host at the same time. Virtual machines that vCenter Server manages

can also run on a cluster of hosts.

Figure 3 shows the relationships among the basic components of vSphere and how vCenter Server can be used

to manage hosts and run virtual machines.

vCenter Server Installation

Install vCenter Server to manage multiple hosts.

To get started with vCenter Server quickly and manage the host you set up, you can install vCenter Server on

a desktop or laptop. You must install vCenter Server on a Windows machine that has network access to the

ESXi host. For production use, VMware recommends that you install vCenter Server on a dedicated server

system.

Before you install vCenter Server, make sure your system meets the minimum hardware and software

requirements. vCenter Server requires a database. vCenter Server uses Microsoft SQL Server 2005 Express for

small deployments with up to 5 hosts and 50 virtual machines. For larger deployments, VMware supports

several Oracle and Microsoft SQL Server databases. Refer to the vSphere Compatibility Matrixes for the list of

supported databases.
