Which appliances do I need?

This article is designed to help you choose the right OT appliances for your sensors and on-premises management consoles. Use the tables below to understand which hardware profile best fits your organization's network monitoring needs.

Physical or virtual appliances can be used; results depend on hardware and resources available to the monitoring sensor.

Note

The performance, capacity, and activity of an OT/IoT network may vary depending on its size, capacity, protocols distribution, and overall activity. For deployments, it is important to factor in raw network speed, the size of the network to monitor, and application configuration. The selection of processors, memory, and network cards is heavily influenced by these deployment configurations. The amount of space needed on your disk will differ depending on how long you store data, and the amount and type of data you store.

Performance values are presented as upper thresholds under the assumption of intermittent traffic profiles, such as those found in OT/IoT systems and machine-to-machine communication networks.

IT/OT mixed environments

Use the following hardware profiles for high bandwidth corporate IT/OT mixed networks:

Hardware profile SPAN/TAP throughput Max monitored Assets Deployment
C5600 Up to 3 Gbps 12 K Physical / Virtual

Monitoring at the site level

Use the following hardware profiles for enterprise monitoring at the site level, typically collecting multiple traffic feeds:

Hardware profile SPAN/TAP throughput Max monitored assets Deployment
E1800 Up to 1 Gbps 10K Physical / Virtual
E1000 Up to 1 Gbps 10K Physical / Virtual
E500 Up to 1 Gbps 10K Physical / Virtual

Production line monitoring (medium and small deployments)

Use the following hardware profiles for production line monitoring, typically in the production/mission-critical environments:

Hardware profile SPAN/TAP throughput Max monitored assets Deployment
L500 Up to 200 Mbps 1,000 Physical / Virtual
L100 Up to 60 Mbps 800 Physical / Virtual
L60 Up to 10 Mbps 100 Physical / Virtual

On-premises management console systems

On-premises management consoles allow you to manage and monitor large, multiple-sensor deployments. Use the following hardware profiles for deployment of an on-premises management console:

Hardware profile Max monitored sensors Deployment
E1800 Up to 300 Physical / Virtual

Next steps

Continue understanding system requirements, including options for ordering pre-configured appliances, or required specifications to install software on your own appliances:

Then, use any of the following procedures to continue:

Reference articles for OT monitoring appliances also include installation procedures in case you need to install software on your own appliances, or reinstall software on preconfigured appliances.
