Summary

When planning the deployment for switching Core Protection Module (CPM) endpoints from default Conventional Scan method to Smart Scan method, refer to the following information for recommended numbers of CPM endpoints before starting deployment.

The following table describes the Smart Protection Relay test environment:

The following table shows the recommended number of CPM endpoints for extreme scenarios. Extreme scenarios include situations like the first 24 hours after switching CPM endpoints to Smart Scan method, or everyone coming back to work after a two-week long holiday.

Standard Machine100016%
Low-end Machine50026%
 
The CPU loading in the table above only shows the average load. Loading/performance may vary depending on different hardware. Please also take available bandwidth into deployment consideration when locating relays at remote sites.

For CPM v10.5, Trend Micro suggests deploying one layer relays for best performance. That means all Smart Protection Relays will directly query Smart Protection Servers. Administrators can determine how many Smart Protection Servers they need to deploy based on the number of CPM endpoints under Smart Protection Relays.

To reach the maximum capacity for one Smart Protection Server, Trend Micro suggests deploying Smart Protection Server on high-end machines.

The following table describes the Smart Protection Server test environment.

The capacity data and VM environment details in the test results shown in the table below are based on dedicated virtual machine resource usage (including virtual processors and memory).

Trend Micro also suggests this configuration to achieve supporting the recommended number of CPM endpoints listed in the table below. If the machine hosting Smart Protection Server is resource shared by other VMs, performance and scalability may drop depending on the system resource arrangements for the other VM applications on the same host machine.

For the recommended 50,000 CPM endpoints, Trend Micro suggests switching CPM endpoints to Smart Scan method in batches. One batch at most should not have more than 5,000 endpoints.

After all endpoints are switched to Smart Scan method, it is also suggested to configure scheduled scans in batches to avoid heavy traffic between Smart Protection Server/Relay and CPM endpoints. Again, in a corporate with 50,000 CPM endpoints, one batch at most should not have more than 5,000 endpoints running scheduled scan simultaneously.

Smart Protection Relay's default network throttle settings can be used when outbound bandwidth is more than 20 Mbps. With default settings, Smart Protection Relay will only use up to 9 Mbps on a 20 Mbps network environment.

If the total outbound bandwidth is less than 20 Mbps, please use the BigFix Fixlet to customize the bandwidth that a Smart Protection Relay is allowed to use. Supported outbound bandwidths are:

  • 10Mbps
  • 6Mbps
  • 2Mbps
  • 512Kbps
  • 256Kbps

The network throttle settings that a Smart Protection Relay uses and their recommended number of smart scan endpoints supported under different bandwidth settings are listed in the table below:
