## Factry Historian system requirements

### Disk

Required disk space starts at 100GB and should be expanded based on expected write load.

It is recommended to have a separate block device / disk for influxDB data. We recommend a root partition of 50GB.

The required disk space for the influxDB disk varies per installation. A consistent 1.000 writes per second for 1 year will use approximately 60GB. This number can vary based on the collected data but can serve as a general guideline. So based on your expected write load and retention policies you can estimate the required disk space.

### System

Aside for the writes per second the other main bottleneck for influxDB is the query complexity and frequency.

| **Load** | **Writes / second** | **Queries / second** |
| -------- | ------------------- | -------------------- |
| Low      | \< 5.000            | \< 5                 |
| Moderate | \< 100.000          | \< 25                |
| High     | >= 100.000          | >= 25                |

**Low**

- **CPU**: 4 cores
- **Memory**: 8 GB RAM
- **Database disk**: >= 500 IOPS

**Moderate**

- **CPU**: 8 cores
- **Memory**: 16 GB RAM
- **Database disk**: >= 1.000 IOPS

**High**

High loads should be tested before being deployed to production:

- **CPU**: 16 cores
- **Memory**: 32 GB RAM
- **Database disk**: >= 1.000 IOPS

Required disk space starts at 100GB and should be expanded based on expected write load.

### InfluxDB

Factry Historian requires InfluxDB to be installed.

- [Download InfluxDB](https://portal.influxdata.com/downloads/)
- [Install instructions](https://docs.influxdata.com/influxdb/v1.8/introduction/install/)

Once installed make sure to [setup an admin user](https://docs.influxdata.com/influxdb/v1/administration/authentication_and_authorization/#admin-users) and [enable authentication](https://docs.influxdata.com/influxdb/v1.8/administration/authentication_and_authorization/)!

## Collector system requirements

**Recommendations per collector:**

- CPU: 1 core
- RAM: 512 MB
- Disk space: at least 5GB of free disk space for buffering

**Operating system**

- Windows or Linux
