3 Service Limits
This chapter contains the service limits for Oracle Private Cloud Appliance. The limits presented here have been tested and are fully supported by Oracle.
The minimum appliance configuration contains three compute nodes and one high-capacity disk shelf with 100TB of usable disk space. Both compute and storage capacity can be expanded by adding compute nodes and disk shelves.
Tenancy Resource Configuration Limits
This section lists the resource limits that are dependent on the appliance architecture. Oracle Private Cloud Appliance supports up to 8 tenancies; these are default limits per tenancy. The numbers provided here apply to any Private Cloud Appliance installation, regardless of its hardware configuration.

System Load and Concurrency Limits
This section shows how many concurrent operations of a given type Oracle Private Cloud Appliance can manage at any given time. The limits presented in the table apply across the entire system and all tenancies. For each of these limits it is assumed that no other operations of any kind are running at the same time. When a limit is exceeded, an error with code 409 or 429 is displayed.

Note:
In addition, there is a system limit on the number of concurrent user sessions:
-
Compute Web UI: 15 tenancy users (5 sessions per management node)
-
Service Web UI: 9 administrators (3 sessions per management node)
An authentication error is displayed when the limit is reached. An inactive user session times out after 1 hour.
