I have forgotten the link to link to what javi has published. Good news is that i have copy and paste it into a note. This is what is recommended by eBox. Hope it is useful.
= eBox Platform Hardware Requirements =
eBox Platform runs on standard x86 hardware. The hardware requirements for an eBox server depends on the modules you install and how many users will you provide service and their usage patterns.
Some modules have low requirements like ''Firewall'', ''DHCP'' or ''DNS'' but others like ''Mailfilter'' or ''Antivirus'' needs more RAM memory and CPU. ''Proxy'' and ''File sharing'' modules would benefit from faster disks due their intensive I/O usage.
A RAID setup, like RAID1 (mirroring) gives a level of security against hard disk failures and increased speed on read operations, particularly interesting for the ''Proxy'' module. eBox has built-in software RAID monitoring.
If you use eBox has a gateway or firewall, at least two NIC (network cards) will be necessary but if you use it has a standalone server, one NIC could be enough.
For a general purpose server with the usual usage patterns these would be the recommended requirements:
|| || CPU || Memory || Disk ||
|| 1-50 users || single core || 1G || 100G (SATA) ||
|| 50-150 users || dual core || +2G || 350G (SATA or SAS) ||
|| +150 users || quad core || +4G || +500G (SAS) ||
