Dell PowerEdge MX840c CTO Compute Sled Blade Server Product Description

The DellPowerEdge MX840c blade server, designed for the PowerEdge MX kinetic infrastructure ecosystem, provides dense four-socket computing, memory and storage for the modern data center.

Powerful and flexible, four-socket dual-width computing sled powered by up to four scalable 2nd generation 28-core Intel Xeon processors. PowerEdge MX840c features a large memory footprint with up to 48 DDR4 DIMMs. It supports up to eight SAS / SATA (HDD / SDD) or Express Flash NVMe PCIe 2,5-inch drives. The PowerEdge MX7000 chassis supports up to four MX840c servers.

  • Exceptionally wide memory configuration capabilities of up to 3 TB (RDIMM) or 6,1 TB (LRDIMM); supports up to 192GB NVDIMM for large applications in memory
  • Supports up to 24 Intel OptaneTM DC DCPMM persistent memory slots (12,2 TB) with a maximum total capacity of 15,36 TB per server
  • Choice of optional M.2 boot optimized storage solution (BOSS) or Internal dual microSD module (IDSDM), to optimize the operating system and data storage
  • Express Flash NVMe PCIe SSD option for high performance direct connect storage requirements


Simplify management and automate intelligently

All PowerEdge servers feature the Dell Remote Access Controller (iDRAC) 9 integrated and agentless integrated with Lifecycle Controller (LC) to simplify the management of server systems. Dell EMC OpenManage Enterprise - Modular Edition (OME-Modular) provides comprehensive system management within the PowerEdge MX7000 server chassis. Offering important OpenManage Enterprise systems management skills, the OME-Modular unified Web / RESTful API interface manages the entire PowerEdge MX environment, including computer, storage and network.

  • Deploy, monitor, manage, configure, update, troubleshoot, and fix Dell EMC servers from anywhere, regardless of the operating system or the presence or state of the hypervisor.
  • Accelerate system management performance with an enhanced iDRAC9 processor, up to four times better performance than the previous generation.


Lay the foundation for the modern data center

Designed for Dell EMC's PowerEdge MX kinetic infrastructure ecosystem, the PowerEdge MX840c server, with dense computing, exceptionally large memory capacity and highly expandable storage subsystem, offers the flexibility and agility needed in today's demanding shared resource environments.

  • Double width; up to four sleds per PowerEdge MX7000 chassis.
  • Two or four scalable second-generation Intel Xeon processors with up to 28 cores per sled, up to 448 cores per chassis.
  • Up to 48 DDR4 DIMM slots, maximum memory of 6 TB and speeds up to 2933MT / s; up to 192 DIMMS per chassis for up to 24,5 TB of maximum memory.
  • Supports up to 24 DIMM slots for Intel Optane DC DCPMM persistent memory (12,2 TB) with a maximum total capacity of 15,36 TB per server.
  • Up to eight 2,5 "drive bays for SAS / SATA (HDD / SDD) and NVMe PCIe SSD support plus optional M.2 boot. 


Configure dynamically to optimize workload performance and efficiency

The PowerEdge MX architecture disaggregates and reallocates resources in a granular manner, maximizing utilization, minimizing over-provisioning and idle infrastructure. The fully configurable PowerEdge MX840c without compromising computing maximizes scalability to improve performance and workload optimization.

  • Scale computing resources with scalable, second-generation Intel Xeon processors and fine-tune performance based on your unique workload requirements.
  • Flexible memory configurations with capacities from 8 GB to 6 TB; RDIMMs and LRDIMMs for reduced memory loading and higher density.
  • Large, high-performance onboard storage area with twice as many HDD drives per computing medium.
