System Requirements


For hardware, virtual and cloud environments, the base requirements are as follows:

Base System
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
Mouse Not required
Monitor and Keyboard Required for installation only

Size Requirements

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
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:

Hardware Requirements


All modestly modern hardware includes a compatible CPU. For those installing ClearOS on very old hardware, the CPU requirement is as follows:

  • Intel architectures from Pentium 6 and onward
  • AMD architectures from Athlon and onward

Network Cards

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.

Internet Connection

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.

RAID Support
