POWER EDGE R940
Scale-up powerhouse for mission
critical workloads
The PowerEdge R940 is designed to power your mission
critical applications and real-time decisions. With four sockets
and up to 12 NMVe drives, the R940 provides scalable
performance in just 3U
Breathtaking performance for mission-critical workloads
The scalable business architecture of the Dell EMC PowerEdge R940
can deliver the most mission critical workloads.
With automatic workload tuning for many workloads, configuration is
quick. Combined with up to 15.36TB of memory and
13 PCIe Gen 3 slots, the R940 has all the resources to maximize
application performance and scale for future demands.
• Maximize storage performance with up to 12 NVMe drives and ensure
application performance scales easily.
• Optimized for software defined storage with a special 2-socket
configuration delivering 50% more UPI bandwidth
compared to a regular 2-socket server.
• Free up storage space using internal M.2 SSDs optimized for boot.
• Eliminate bottlenecks with up to 15.36TB of memory in 48 DIMMS,
24 of which can be Intel® Optane™ DC persistent
memory DCPMMs
