In Basic deployment mode, a single standalone instance of the vCenter Single
Sign-On server supports the connectivity of Active Directory, OpenLDAP,
Local Operating System, and vCenter Single Sign-On embedded users and
groups. In most cases, the vCenter Single Sign-On instance is installed on the
same host machine as vCenter Server, as with the vCenter Server Simple
Install option, or the vCenter Server Appliance.
The Basic vCenter Single Sign-On deployment is appropriate in the following
circumstances:
If you have a single vCenter Server of any supported inventory size: up
n
to 1,000 hosts or 10,000 virtual machines.
If you have multiple geographically dispersed locations, each with a
n
local vCenter Server and you do not require a single-pane-of-glass view
as provided by vCenter Linked Mode.
For this deployment mode, you install a vCenter Single Sign-On primary
instance and one or more additional vCenter Single Sign-On nodes. Both the
primary and high availability instances are placed behind a third-party
network load balancer (for example, Apache HTTPD or vCNS). Each vCenter
Single Sign-On has its own VMware Directory Service that replicates
information with other vCenter Single Sign-On servers. vCenter Single Sign-
On administrator users, when connected to vCenter Server through the
vSphere Web Client, will see the primary vCenter Single Sign-On instance.
This deployment mode has the following limitations:
It provides provides failover only for the vCenter Single Sign-On
n
service. It does not provide failover for the vCenter Single Sign-On host
machine and it does not load balance requests between vCenter Single
Sign-On nodes.
It supports the connectivity of Active Directory, OpenLDAP and
n
vCenter Single Sign-On embedded users and groups, but does not
support the use of local operating system user accounts.
See "vCenter Single Sign-On and High Availability,"
availability options.
This mode is designed for vCenter Server deployments with multiple
physical locations. Multisite deployment is required when a single
administrator needs to administer vCenter Server instances that are
deployed on geographically dispersed sites in Linked Mode.
