In case the requirements change, the CX400 M4 makes it possible to gradually add or remove server nodes as required by the business needs.
Superior performance in a dense form factor
The PRIMERGY CX400 M4 is among the most versatile general-purpose enterprise infrastructure and application servers in the industry. The chassis can be equipped with different kinds of server nodes featuring latest generation Intel® Xeon® processors and Intel® Optane DC persistent memory technology for various usage scenarios. Apart from that, selected servers can also be equipped with high-end NVIDIA Tesla accelerator cards.
The PRIMERGY CX400 M4 is a scalable IT infrastructure enabling flexible and fast response to rapidly changing IT demands. It provides an ideal platform for scale-out workloads such as virtualization, all kinds of enterprise applications, high performance computing, deep learning or data analytics.
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.
Revolutionize data center management
Fujitsu ServerView Suite is a free-of-charge management software including tools for installation and deployment, permanent status monitoring and control as well as BIOS, firmware and selected software updates. In addition, FUJITSU Software Infrastructure Manager (ISM) provides converged management across multiple data centers. The new ISM Essential license, available free-of-charge provides essential server management and converged monitoring functions.
Fujitsu offers comprehensive infrastructure management and server management solutions which is key to efficient data center operations. They provides all the functions for flexible and automated 24x7 IT operations and improves end-user productivity via intelligent and innovative system management solutions. ISM helps improve data center efficiency and overall IT productivity with converged infrastructure management, paving the path to software-defined data center.
