ServMax® A-28-IN

2U 4Node High Density Server up to 8x AMD EPYC™ 7003 Series Processor and 8x 2.5” Hot-Swappable U.2 SSD Bays in a 1-Phase Immersion Cooling Setting

  • Immersion Cooling Ready – Full warranty provided including both system and components
  • Each node supports two 3rd Gen AMD EPYC™ 7003 series processors with 16x DIMMS
  • Each node has 2x 2.5” Gen4 U.2 hot-swappable SSD bays and 1x M.2 with PCIe Gen4 x4 interface

The ServMax® A-28-IN is the ideal 2U 4Node high-density server for converting your data center to the most efficient immersion cooling configuration, which not only maximizes system performance but also reduces OpEx by more than 50%. This system, which is powered by dual 3rd Gen AMD EPYCTM 7003 processors, can support up to four dual-slot GPUs such as NVIDIA A100 and OCP 3.0 expansions to meet the growing demands for data centers, web servers, virtualization, cloud, and hyperscale environments.


The A-28-IN is designed for mission-critical infrastructures and ensures high reliability during emergencies such as power outages through innovative designs such as Smart Ride Through (SmaRT) and Smart Crises Management and Protection (SCMP). SmaRT, for example, provides a 10-20 ms buffer time to allow the system to transition to a backup power source without disrupting service.


Finally, this system has been certified for hyper-scale deployment by key enterprise software vendors, including Linux distributions (SUSE, RedHat, and Ubuntu), virtualization, and the cloud (Citrix, VMWare, and Microsoft Azure). Such certification enables the end user to rapidly develop and validate joint solutions while maintaining speed, agility, and cost effectiveness.
