Hardware requirements
When installing the system on real hardware or on VM please consider our recommended requirements. Note that this are the absolute minimum hardware requirements.
Requirements depend on:
- Number of clients online
- For 250 concurrent users and more, a CPU core speed of more than 2.5 GHz is recommended
- Used features (CPU intensive features are: Application Control, Connection tracking, many VLANs)
- DNS filter needs more memory (4 GB)
| Users | CPU cores | GB RAM | GB DISK |
|---|---|---|---|
| 10 | 1 | 2 GB | 20 GB |
| 25 | 1 | 2 GB | 20 GB |
| 50 | 2 | 2 GB | 30 GB |
| 75 | 2 | 2 GB | 30 GB |
| 100 | 2 | 2 GB | 60 GB |
| 175 | 2 | 2 GB | 60 GB |
| 250 | 4 | 4 GB | 100 GB |
| 375 | 4 | 4 GB | 100 GB |
| 500 | 4 | 4 GB | 150 GB |
| 750 | 4 | 4 GB | 150 GB |
| 1000 | 4 | 8 GB | 200 GB |
| 1500 | 4 | 8 GB | 200 GB |
| 2000 | 8 | 8 GB | 250 GB |
| 3000 | 8 | 16 GB | 250 GB |
| unlimited | 8 | 16 GB | 300 GB |
As a rule of thumb CPU cores and memory are much more critical than disk space.
- Also for the smallest licenses, at least 2 CPU cores should be used for system stability.
- As RAM is used by the Linux kernel for caching, more RAM means more speed for juggling traffic.
Network cards
When expecting a significant amount of traffic, consider using a 10 GBit/s network card.
Such network cards provide CPU offloading like TCP checksum calculations and are therefore recommended even if 1GBit/s is not surpassed.
Demo VMs
When setting up a IACBOX demo system it’s sufficient to use
- 1 CPU Core
- 2 GB RAM (4GB if DNS Filtering is active)
- 10 GB of disk space
