vCenter Server Setup
Increasing the number of vCenter Server instances in your Orchestrator setup causes Orchestrator to
manage more sessions. Each active session results in activity on the corresponding vCenter Server, and too
many active sessions can cause Orchestrator to experience timeouts when more than 10 vCenter Server
connections occur.
For a list of the supported versions of vCenter Server, see VMware Product Interoperability Matrix.
NOTE You can run multiple vCenter Server instances on different virtual machines in your Orchestrator
setup if your network has sufficient bandwidth and latency. If you are using LAN to improve the
communication between Orchestrator and vCenter Server, a 100Mb line is mandatory.
Authentication Methods
To authenticate and manage user permissions, Orchestrator requires a connection to an LDAP server or a
connection to a vCenter Single Sign-On server.
Orchestrator supports the Active Directory, OpenLDAP, eDirectory, and Sun Java System Directory Server
directory service types.
When you install Orchestrator together with vCenter Server, the Orchestrator server is preconfigured to use
vCenter Single Sign-On as an authentication method.
When you install Orchestrator standalone, it is preconfigured to use an embedded LDAP server. The
embedded LDAP server is suitable for testing purposes only. If you want to use Orchestrator with an LDAP
server in a production environment, you must set up a separate LDAP server and configure Orchestrator to
connect to it.
If you download and deploy the Orchestrator Appliance, the Orchestrator server is preconfigured to work
with the OpenLDAP server distributed together with the appliance. The default OpenLDAP configuration is
suitable for small- or medium-scale environment. To use Orchestrator in a production environment, you
must set up either an LDAP server or a vCenter Single Sign-On server and configure Orchestrator to work
with it.
To use LDAP server, you must connect your system to the LDAP server that is physically closest to your
Orchestrator server, and avoid connections to remote LDAP servers. Long response times for LDAP queries
can lead to slower performance of the whole system.
To improve the performance of the LDAP queries, keep the user and group lookup base as narrow as
possible. Limit the users to targeted groups that need access, rather than to whole organizations with many
users who do not need access. The resources that you need depend on the combination of database and
directory service you choose. For recommendations, see the documentation for your LDAP server.
To use the vCenter Single Sign-On authentication method, you must first install vCenter Single Sign-On. If
you install Orchestrator separately from vCenter Server and want to use vCenter Single Sign-On, you must
configure the Orchestrator server to use the vCenter Single Sign-On server that you installed and
configured.
Orchestrator Database Setup
Orchestrator requires a database to store workflows and actions.
If you install Orchestrator together with vCenter Server, the Orchestrator server is preconfigured to use the
vCenter Server datasource (vDB) and no additional configuration of the database is required. However, if
you need to use a separate database, you can configure Orchestrator to use a dedicated database by using
the Orchestrator configuration interface.
