The power of a 4U rackmount computer

For high-performance computing power in harsh and hazardous conditions, an industrial 4U rackmount computer can provide exceptional reliability and superior performance. The rackmount form factor also enables faster installation, easier maintenance and greater flexibility for managing networking and cabling.

As a leading manufacturer of innovative and highly engineered industrial computers, Comark provides several options for a 4U rackmount computer designed to work in the harshest environments around the world.

Features of an industrial 4U rackmount

When you need computing technology you can trust to power industrial automation, building control and fire and life safety applications, a 4U industrial rackmount computer provides:

  • Superior performance. Industrial computers are built for the high-performance computing requirements of industrial applications, automation and artificial intelligence.
  • Greater flexibility. A 4U rackmount PC provides many more drive bays and I/O expansion slots than a 1U rackmount PC or 2U rackmount PC, delivering more flexibility as IT teams configure processing power and storage capacity for the specific requirements of industrial workloads.
  • Rugged reliability. An industrial rackmount computer is designed to work reliably in the harsh computing environments of industrial and military applications, withstanding high temperatures, shock and vibration, the presence of dust and dirt and exposure to water.
  • Longer lifecycle. An industrial 4U rackmount computer will continue to perform and to provide replacement parts and upgrade paths for years longer than standard consumer-grade PCs, enabling IT teams to standardize on specific configurations.
  • Tighter security. The ability to lock a 4U rackmount computer within the chassis of a server rack provides additional protection against unauthorized access.
