vCenter Server 7 arrives with many new features such as vCenter Server Profiles and Update Planner. Learn more about how vCenter Server 7 helps simplify Lifecycle operations in this video.
Adam Eckerle (@eck79) and Emad Younis (@emad_younis) covers vCenter’s 6.5 server architecture and platform services. The vCenter high availability architecture uses a three-node cluster to provide availability against multiple types of hardware and software failures. In this video we have a deep dive discussion on the vSphere Sign Sign-On domain components and what role they play. We also cover terminology, decommission, and backup of these components.

This video demonstrates how to backup and restore an embedded vCenter Server 6.0 vPostgres database. Backing up your database protects the data stored in your database. Of course, restoring a backup is an essential part of that function.
This follows up on our recent blog & video: How to backup and restore the embedded vCenter Server Appliance 6.0 vPostgres database.
Note: This video is only supported for backup and restore of the vPostgres database to the same vCenter Server. Use of image-based backup and restore is the only solution supported for performing a full, secondary appliance restore.
The VMware vCenter Server™ 6.0 release introduces new, simplified deployment models. The components that make up a vCenter Server installation have been grouped into two types: embedded and external. Embedded refers to a deployment in which all components—this can but does not necessarily include the database—are installed on the same virtual machine. External refers to a deployment in which vCenter Server is installed on one virtual machine and the Platform Services Controller (PSC) is installed on another. The Platform Services Controller is new to vCenter Server 6.0 and comprises VMware vCenter™ Single Sign-On™, licensing, and the VMware Certificate Authority (VMCA).
Embedded installations are recommended for standalone environments in which there is only one vCenter Server system and replication to another Platform Services Controller is not required. If there is a need to replicate with other Platform Services Controllers or there is more than one vCenter Single Sign-On enabled solution, deploying the Platform Services Controller(s) on separate virtual machine(s)—via external deployment—from vCenter Server is required.
This paper defines the services installed as part of each deployment model, recommended deployment models (reference architectures), installation and upgrade instructions for each reference architecture, postdeployment steps, and certificate management in VMware vSphere 6.0.
VMware vCenter Server 6.0 Services
A few requirements are common to both installing vCenter Server on Microsoft Windows and deploying VMware vCenter Server Appliance™. Ensure that all of these prerequisites are in place before proceeding with a new installation or an upgrade.
- DNS – Ensure that resolution is working for all system names via fully qualified domain name (FQDN), short name (host name), and IP address (reverse lookup).
- Time – Ensure that time is synchronized across the environment.
- Passwords – vCenter Single Sign-On passwords must contain only ASCII characters; non-ASCII and extended (or high) ASCII characters are not supported.
Installing vCenter Server 6.0 on a Windows Server requires a Windows 2008 SP2 or higher 64-bit operating system (OS). Two options are presented: Use the local system account or use a Windows domain account. With a Windows domain account, ensure that it is a member of the local computer’s administrator group and that it has been delegated the “Log on as a service” right and the “Act as part of the operating system” right. This option is not available when installing an external Platform Services Controller.
Windows installations can use either a supported external database or a local PostgreSQL database that is installed with vCenter Server and is limited to 20 hosts and 200 virtual machines. Supported external databases include Microsoft SQL Server 2008 R2, SQL Server 2012, SQL Server 2014, Oracle Database 11g, and Oracle Database 12c. When upgrading to vCenter Server 6.0, if SQL Server Express was used in the previous installation, it will be replaced with PostgreSQL. External databases require a 64-bit DSN. DSN aliases are not supported.
When upgrading vCenter Server to vCenter Server 6.0, only versions 5.0 and later are supported. If the vCenter Server system being upgraded is not version 5.0 or later, such an upgrade is required first.
Table 2 outlines minimum hardware requirements per deployment environment type and size when using an external database. If VMware vSphere Update Manager™ is installed on the same server, add 125GB of disk space and 4GB of RAM.
