For hardware, virtual and cloud environments, the base requirements are as follows:
|Processor/CPU||32-bit or 64-bit|
|Memory/RAM||At least 1 GB is recommended (see guidelines below)|
|Hard Disk||At least 10 GB is recommended (see guidelines below)|
|Network||Ethernet, cable, DSL|
For hardware installs, the requirements are as follows:
|Network Cards||A network card is required, two for gateway mode|
|CD-ROM Drive||Required for CD installation only|
|USB||Required for USB key installation only|
|Monitor and Keyboard||Required for installation only|
The following are guidelines for estimating the right hardware for your system. Keep in mind, the hardware required depends on how you use the software.
|RAM and CPU||5 users||5-25 users||25-50 users||50-250 users||250+ users|
|Processor/CPU||Low-Power||Basic||Dual-Core||Quad-Core||Multi-Core + Multi-Processor|
|Memory/RAM||1-2 GB||2-4 GB||4-8 GB||8-16 GB||16-32 GB|
|Hard Disk||Installation and logs require 1 GB - optional storage is up to you|
|RAID||Recommended for mission critical systems|
The following software modules are processor and memory intensive:
All modestly modern hardware includes a compatible CPU. For those installing ClearOS on very old hardware, the CPU requirement is as follows:
Generally, ClearOS does a good job at auto-detecting hardware and most mass-market network cards are supported. ClearBOX also includes wireless support and you can read more about this hardware solution here. Though wireless card drivers are included in ClearOS, wireless is not officially supported in the software version.
ClearOS supports most DSL (including PPPoE), cable modem broadband Internet connections and standard Ethernet connections. ISDN and satellite broadband are not supported unless terminated with a standard Ethernet connection.
