Features & Benefits

Features Benefits
Compact and modular foundation
  • The PRIMERGY CX400 M4 features up to 4 half-wide dual socket server nodes plus up to 24 storage drives in a single 2U enclosure.
  • The enclosure allows nodes and components to share power, cooling and management.
  • Hot-plug and redundant power supply units, hot-plug and redundant fan modules for maximum reliability.

  • 50% less rack space in comparison with standard rack servers.
  • Comprehensive ecosystem making it ideal for VDI, virtualization, High Performance and Technical Computing, Web Services and Cloud Computing.
  • Gradually add or remove server nodes as required by the business needs.
Versatile performance for any computing need
  • Various server nodes featuring latest generation Intel® Xeon® processors to best match particular workloads.
  • Intel® Xeon® Processor Scalable Family with up to 28 cores relying on Intel® UltraPath Interconnect for an increased data rate between the CPUs.
  • Server nodes available with high-end computational and graphics performance based on advanced GPU accelerators.
  • Latest DDR4 memory technology with 2,666 MHz.
  • Up to 24x 2.5” hot-plug storage drives.

  • Scalable IT infrastructure enabling flexible and fast response to rapidly changing IT demands.
  • Ready for the future and data growth scenarios.
  • DDR4 memories with higher bandwidth and lower consumption are the enabler; optimized for virtualization and clouds, data centers and high performance computing.
  • Flexible expandability and diverse options.
Traditional air cooling or optional liquid cooling
  • The PRIMERGY CX400 M4 can be used with standard air cooling or optionally with liquid cooling technology.
  • The liquid cooling solution removes heat from CPUs, GPUs, and memory modules within servers using water as hot as 40 °C (105°F), eliminating the need for chilling to cool these components.

  • Cool-Central® Liquid Cooling Technology is the ideal solution to overcome cooling as well as power challenges, and to significantly reduce investment and operating costs in the data center.
  • “Free cooling” solution that captures between 60% and 80% of server heat, reducing data center cooling cost by over 50% and allowing 2.5x-5x increases in data center server density.
Simplify Complexity
  • Fujitsu ServerView Suite including tools for installation and deployment, permanent status monitoring and control.
  • BIOS, firmware and selected software are updated free of charge.
  • iRMC S5 comes with new interactive web UI and conforms to Redfish providing unified API support for heterogeneous environment.

  • Enable faster IT service by automating and simplifying infrastructure operations across compute, storage and networking with ServerView Infrastructure Software Manager.
  • The comprehensive tools of the Fujitsu ServerView Suite ease the administrator’s life.
  • Providing increased security and server administrator productivity, iRMC S5 simplifies server management.
