Capacity Requirements
The number of connectors that you deploy within a connector group depends on the volume of traffic that you expect.
- Estimate the maximum expected volume of traffic to the resources in the data center, branch office, or security zone.
- When you add a connector group, Secure Access suggests a suitable number of connectors to deploy based on the estimated traffic volume you provide. The recommended number of connectors assumes the recommended instance type, 75% CPU usage, and DTLS connectivity, and includes a connector instance for redundancy.
- For connectors that have the recommend instance type, throughput using DTLS is 500 mbps fully loaded (400 at the recommended 75% load). Throughput using TLS is 250 mpbs. If your actual capacity is less than expected, see Troubleshoot Resource Connectors and Connector Groups.
- To determine the number of connectors needed for an existing connector group, see Determine the Number of Connectors Needed in a Connector Group.
- For redundancy, (for example, to avoid service interruptions during connector upgrades), you should deploy at least two connectors in each group.
- For the maximum number of connectors and connector groups per organization, see Limitations and Range Limits.
- You can deploy up to the maximum number of connectors in a group for load balancing and scalability.
- You can associate up to the maximum number of connector groups with any region.
- If you require greater capacity, contact your Cisco representative.
- Your network must be able to support the traffic volume that you specify.
