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, try to use at least 2 CPU cores.
- As RAM is used by the Linux kernel for caching, more RAM means more speed for juggling traffic.
Network cards
If you have significant amount of traffic, consider to use 10 GBit/s network cards (although you might not exceed 1Gbit/s). Such network cards provide CPU offloading like TCP checksum calculations.
Demo VMs
If you want to setup a IACBOX demo system it’s sufficient to use
- 1 CPU Core (but of course 2 cores give you better responsiveness)
- 2 GB RAM (for DNS filter you need 4GB)
- 10 GB of disk space
