System Requirements

refer to the following system requirements for running belden horizon data operations minimum requirements a belden horizon data operations instance is designed to collect, analyze, and forward data these data operations could require heavy computing resources to be able to facilitate all the day to day processes a belden horizon data operations instance will execute although it is possible to run belden horizon data operations on a wide range of devices, not having enough computing resources for your particular scenario could create serious performance issues consider the following factors when deciding upon the hardware that your belden horizon data operations will use what is the amount of data that will be processed? what is your hardware budget? how many devices will you connect to belden horizon data operations? how many flows/analytics/applications/integrations will you need? what programming language and frameworks will you use? will you need frequent belden horizon data manager belden horizon data operations interactions (for example, in the case of automatic backups) as well? to address some of these questions, we recommend you first install belden horizon data operations on a test virtual machine (vm) then run a partial execution of all your possible workloads to see how it performs from there, you can get a better idea whether you need less, about the same, or a multiplying factor of your test vm's computing resources see below for setting up this vm deployment requirements bhdo can be deployed using docker, iso or ova files, and is compatible with both x86 and arm architectures the following table summarizes the minimum compute requirements when running bhdo in a vm or container minimum compute requirements (vm) minimum compute requirements (container) cores 2 2 memory 4 gb 2 gb storage 20 gb 10 gb recommended configurations a belden horizon data operations instance is typically customized under one of the following three configurations data pass through reading and passing data executed externally exclusively on integrations minimal data processing and/or storage performed on the belden horizon data operations instance most computing resources consumed by only devicehub and data storage/forwarding to integrations in stream processing low volume in stream processing of data using flows and/or analytics (for example, value change or anomaly detection) data stored in influxdb for local visualization using a container running the grafana or python application computing resources consumed by influxdb, flows, analytics, containers, and devicehub heavy in stream processing and application usage high volume in stream processing of all collected data involving complex flows and analytics multiple flows are configured with the maximum allowed ram in analytics, many groups operate, each including multiple processors several containers may be run for further data processing, traceability, downtime recording, and so on influxdb will require additional cpu and ram resources if a large number of devices and tags are configured each device will become its own influxdb data table (measurement) computing resources consumed by user defined code within flows, applications, and analytics flows the following table summarizes parameters for the above three starting configurations when sizing a belden horizon data operations instance configuration 1 (data pass through) configuration 2 (in stream processing) configuration 3 (heavy in stream processing and application usage) devices 1 5 5 10 10+ average tags per device 10 20 20 100 100+ flows instances 0 4 1 4 1 4 average flow nodes < 10 10 50 50+ analytics 0 5 5 25 25+ applications/containers 0 1 2 2+ integrations 1 2 1 5 5+ influxdb usage optional mandatory mandatory opc ua server usage cannot function with opc ua server can function with opc ua server can function with opc ua server cores 4 8 12+ memory(ram) 8 16 gb 16 32 gb 32+ gb storage (disc) 100 250 gb 250 500 gb 500+ gb nic (network interface) typically at least two one for it network (users, belden horizon data manager, integrations) one for ot network (plc connectivity) typically at least two one for it network (users, belden horizon data manager, integrations) one for ot network (plc connectivity) typically at least two one for it network (users, belden horizon data manager, integrations) one for ot network (plc connectivity) firewall port configuration requirements note you have the option of managing ports in belden horizon data operations see manage firewall rules docid\ zvyrnvndt8tupqf48bn8i to learn more the firewall managing belden horizon data operations' traffic must always open the following ports function for belden horizon data operations port #
