Private Access Connector system requirements and sizing guide

Trend Micro advises against allowing the host to dynamically configure VM resources as is the default in VMware. Instead, configure the VM to reserve at least the number of vCPUs and memory listed in the system requirements.

Trend Micro suggests deploying more private access connectors with lower specifications rather than fewer connectors with higher specifications. This approach enhances horizontal scalability. For instance, if you have fewer higher-specification connectors and one fails, it could disrupt a large amount of user application traffic or sessions. The failure of a lower specification but more numerous connector would have a lesser impact.

Below is an example throughput measured with the following setup:

Note that the actual throughput may vary depending on factors such as the number of concurrent users, your internal network configuration, and latency. Ensure that you have sufficient private access connectors to support the connection and provide room for failover (N+1). To boost overall throughput, add more connectors to the same connector group as needed for your deployment.
