NEC Express5800/A2040e


NEC’s Express5800/A2040e is an enterprise-class 4-socket 4U server based on the Intel® Xeon® Scalable Processor Family. The server represents a new generation of mission critical servers built specifically to support highly virtualized environments, heavy transactional workloads, and in-memory databases. Extensive hardware redundancy and system monitoring minimizes the risk of a single point of failure. Open and affordable, the Express5800/A2040e delivers a smaller footprint and better operational efficiency, and helps to reduce server sprawl.


Exceptional Performance

NEC Express5800/A2040e is a scale-up server design with a massive resource pool to support compute-intensive and memory hungry applications in mission critical and virtualized environments. Powered by the Intel® Xeon® Scalable Processor Family and inheriting NEC’s supercomputer high performance technology, the NEC’s sixth generation enterprise server supports up to 4 processors / 112 cores / 224 threads, 6.0 terabyte of memory, and 16 PCIe 3.0 slots.

High Availability

NEC Express5800/A2040e offers industry-leading reliability, availability, and serviceability (RAS) features required to support business-critical workloads for enterprise computing. Combining Intel’s Run Sure technology with NEC’s mainframe inspired advanced RAS features, the Express5800/A2040e server with built-in service processors and many redundant components offers exceptional availability and serviceability on standard operating systems.

Advanced Flexibility

NEC Express5800/A2040e is highly flexible to support ever demanding and dynamically changing on-premise or cloud workloads for large databases, analytics, and large-scale virtualization. Custom configurations offer ability to populate 2, 3 or 4 sockets, and enable or disable cores based on performance requirements. Provide pay as you grow configurations.

High Efficiency

NEC Express5800/A2040e server offers high power efficiency in 4U design. Industry-leading intelligent power management with 80 PLUS® Platinum certified power supply enable the high power efficiency operation. The server operates in temperatures as high as 40 degrees Celsius, which reduces the total power consumption by lowering cooling requirements.
