Configuring IaaS
A system administrator can adjust concurrency limits for an IaaS Windows server to best use resources,
customize email sent from the server, and enable connections to other machines.
Setting Resource-Intensive Concurrency Limits
To conserve resources, vRealize Automation limits the number of concurrently running instances of
machine provisioning and data collection. You can change the limits.
Configuring Concurrent Machine Provisioning
Multiple concurrent requests for machine provisioning can impact the performance of
vRealize Automation. You can make some changes to limits placed on proxy agents and workflow
activities to alter performance.
Depending on the needs of machine owners at your site, the vRealize Automation server may receive
multiple concurrent requests for machine provisioning. This can happen under the following
circumstances:
n
A single user submits a request for multiple machines
n
Many users request machines at the same time
n
One or more group managers approve multiple pending machine requests in close succession
The time required for vRealize Automation to provision a machine generally increases with larger
numbers of concurrent requests. The increase in provisioning time depends on three important factors:
n
The effect on performance of concurrent resource-intensive vRealize Automation workflow activities,
including the SetupOS activity (for machines created within the virtualization platform, as in WIM-
based provisioning) and the Clone activity (for machines cloned within the virtualization platform).
n
The configured vRealize Automation limit on the number of resource-intensive (typically lengthy)
provisioning activities that can be executed concurrently. By default this is two. Concurrent activities
beyond the configured limit are queued.
