Microsoft SQL Server 2005 Express disk requirements – Up to 2GB free disk space to decompress the
installation archive. Approximately 1.5GB of these files are deleted after the installation is complete.
n
Networking – Gigabit connection recommended.
See your database documentation for the hardware requirements of your database. The database requirements
are in addition to the vCenter Server requirements if the database and vCenter Server run on the same machine.
vCenter Server Software Requirements
Make sure that your operating system supports vCenter Server.
For a list of supported operating systems, see the vSphere Compatibility Matrixes at
http://www.vmware.com/pdf/vsphere4/r40/vsp_compatibility_matrix.pdf on the VMware vSphere
documentation Web site.
vCenter Server Prerequisites
Before installing vCenter Server, review the prerequisites.
n
You must have the installation DVD or download the installation ISO image.
n
Your hardware must meet the vCenter Server hardware requirements.
n
If the machine on which you are installing vCenter Server has VirtualCenter installed, you might want to
upgrade instead of performing a fresh installation of vCenter Server.
IMPORTANT If you want to keep your existing VirtualCenter configuration, see the Upgrade Guide.
n
There must be no Network Address Translation (NAT) between the vCenter Server system and the hosts
it will manage.
n
For the installation of vCenter Server, VMware recommends installing the bundled SQL Server 2005
Express database on one of the supported operating systems. If SQL Native Client is already installed,
uninstall SQL Native Client before you begin the vCenter Server installation.
n
The system that you use for your vCenter Server installation will belong to a domain rather than a
workgroup. If assigned to a workgroup, the vCenter Server system is not able to discover all domains and
systems available on the network when using such features as vCenter Guided Consolidation Service. To
use vCenter Linked Mode, multiple vCenter Server systems should be added to a domain. To determine
whether the system belongs to a workgroup or a domain, right-click My Computer and click Properties
and the Computer Name tab. The Computer Name tab displays either a Workgroup label or a Domain
label.
n
During the installation, the connection between the machine and the domain controller must be working.
n
The computer name cannot be more than 15 characters.
n
The DNS name of the machine must match the actual computer name.
n
Make sure the system on which you are installing vCenter Server is not an Active Directory domain
controller.
n
On each system that is running vCenter Server, make sure that the domain user account has the following
permissions:
n
Member of the Administrators group
n
Act as part of the operating system
n
Log on as a service
n
Assign a static IP address and host name to the Windows server that will host the vCenter Server system.
This IP address must have a valid (internal) domain name system (DNS) registration that resolves properly
from all managed ESX hosts.
