1.1. Hardware requirements for a Zorp Firewall host

CPU: Zorp requires a 64-bit capable x86-64 processor (for example, Intel Core i series, Intel Xeon, AMD Ryzen, AMD EPYC, and so on).

Memory: At least 4 GB main memory is recommended, though 2 GB is acceptable on systems with low load.

Disk: Though Zorp itself requires less than 8 GB of disk space, 256 GB or larger disk space is recommended to have enough space for log files, for example.

Hardware compatibility: Zorp runs on Ubuntu, currently using version 4.15 of the Linux kernel. Most hardware supported by Linux is also supported by Zorp.

Note

Make sure to install Zorp on hardware that is Ubuntu Server certified. For a list of Ubuntu Server certified hardware, see Ubuntu Server certified hardware.

Tip

Use disks designed for servers: other disks are not planned for 24/7 usage, and to participate in RAID sets. Use 2 or more redundant disks in a RAID array to prevent data loss and downtime (the Zorp installer supports software RAID mirroring).

For details on sizing a Zorp host, see Section 1.1.1, Sizing Zorp hosts.

Tip

A modern 1- or 2-unit-high server with remote management port is usually an optimal solution. Its size depends on the number of required LAN ports. Use reliable or brand hardware for your firewall with dual power supply and UPS.
