NF5280A6 is a high-end dual-socket server that uses the 3rd Gen AMD® EPYC Processors. NF5280A6 has high quality and reliability in different application scenarios. With the high computing performance, perfect ecological compatibility and configuration flexibility, NF5280A6 can fulfill a variety of complicated workloads, and particularly fits application scenarios such as data analysis and processing, cloud, and high-performance computing.

Key Features
  • Powerful Performance

    1. Employing the 3rd Gen AMD® EPYC Milan Processors, NF5280A6 supports up to 64 cores and 128 threads per CPU, up to 280 W TDP, a maximum Turbo frequency of 3.7 GHz, and 256 MB L3 cache per CPU and XGMI2 interconnect links at 18 GT/s.

    2. Up to 32 DDR4 ECC memory modules (up to 3200 MT/s, RDIMMs and LRDIMMs), with the maximum capacity of 4 TB[JC(1] , are supported to deliver a high speed and superior availability.

  • Flexible Expansion

    1. Support up to 16 × 3.5" drive or 28 × 2.5" drive.

    2. Support optional OCP NIC 3.0 module with multiple network port options (10/25/40/100/200 Gbps), delivering a more flexible network architecture to applications.

    3. Support up to 8 standard PCIe expansion cards, further enhancing I/O performance.

    4. Support optional internal SATA/PCIe M.2 modules for diverse storage demands.

  • Smart Management

    1. With a user-friendly design, the entire system supports tool-free maintenance. The enhanced and optimized structures realize easy assembly/disassembly and greatly reduce O&M time.

    2. IEIT's unique intelligent regulating technology combined with an advanced air cooling system creates an optimum working environment to ensure server health.

    3. With the latest BMC, technicians can quickly locate components that have failed (or are failing) through the Web GUI, fault diagnosis LEDs and UID LEDs on the front panel, simplifying maintenance, speeding up troubleshooting, and enhancing system availability.

    4. Technicians can monitor system parameters and take appropriate actions in a timely manner via the alarms sent in advance via BMC to ensure system health and minimize system downtime.
