Orchestrator Components Setup
Guidelines 3
To enhance the availability and scalability of your Orchestrator setup, install Orchestrator on a server different
from the server on which vCenter Server runs. Separating Orchestrator from vCenter Server makes it possible
to adjust the operating system to meet the specific recommendations for each service.

vCenter Server Setup
Increasing the number of vCenter Server instances causes Orchestrator to manage more sessions. Each active
session implies activity on the corresponding vCenter and too many active sessions can cause Orchestrator to
experience timeouts when more than 10 vCenter connections occur.
NOTE Run only one vCenter Server on a virtual machine. You can run multiple vCenter 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, a 100Mb line is mandatory.
Directory Services Setup
Orchestrator requires a connection to an LDAP server on your infrastructure.
The supported directory service types are: Active Directory, eDirectory, and Sun Java System Directory Server.
OpenLDAP is not supported and can only be used for testing and evaluation purposes.
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.
Try to limit the users to targeted groups that are going to need access, rather than to whole organizations with
many users who are not going to need access. Depending on the combination of database and directory service
you choose, the resources you need can vary. For recommendations, see third-party documentation.
