Software Requirements for vCenter Server and
Platform Services Controller on Windows
Verify that your operating system supports vCenter Server.
vCenter Server requires a 64-bit operating system, and the 64-bit system DSN is required for
vCenter Server to connect to the external database.
The earliest Windows Server version that vCenter Server supports is Windows Server 2008 SP2. Your
Windows Server must have the latest updates and patches installed. For a full list of supported operating
systems, see http://kb.vmware.com/kb/2091273.
Prior to upgrading or migrating vCenter Server, you must install the Microsoft Update for Universal C
Runtime in Windows. See Update for Universal C Runtime in Windows.
Database Requirements for vCenter Server on Windows
vCenter Server requires a database to store and organize server data.
Each vCenter Server instance must have its own database. For environments with up to 20 hosts and
200 virtual machines, you can use the bundled PostgreSQL database that the vCenter Server installer
can install and set up for you during the vCenter Server installation. A larger installation requires a
supported external database for the size of the environment.
For information about supported database server versions, see the VMware Product Interoperability
Matrix at http://www.vmware.com/resources/compatibility/sim/interop_matrix.php.
