Dell R940 EMC PowerEdge Rack Server 

Overview :

The reduced height of the new Dell EMC PowerEdge R940 server chassis, from 4U to 3U, enables more density compared to the previous generation R930 chassis. The addition of Intel Xeon Scalable processors gives Administrators more cores to work with for virtualization and offers support for 30% more I/O capabilities. With top-of-the-line 28-core Xeon processors, this system delivers a 17% increase in performance over the R930 loaded with 24-core E7-8800 v4 processors again with 1U less space! This is a general-purpose platform designed for high-performance computing, database, e-commerce, and data warehouses.This system is designed to be deployed as a dual or quad-socket platform with a Processor Expansion module (PEM) that supports two additional processors and 24 more memory slots. An optional two-socket configuration offers 50% more CPU bandwidth compared to a standard 2-socket server and is optimized for software-defined storage. Both 1st and 2nd generation Intel Xeon Scalable processors are supported with the Gold and Platinum families supporting three Ultra Path Interconnects for Improved CPU to CPU communication. Other processors are also supported providing only two UPIs and only 768GB per processor. Three UPI channels offer greater performance throughput for quad-socket platforms, so if you want to access the full potential of the system choose your processors accordinglyYou can install either 1st or 2nd-generation Intel Xeon Scalable processors. Each of the processors supports six memory channels that can be populated with two memory modules each for a total of 12 memory slots per processor. With a 2-processor configuration, the Dell PowerEdge R940 server will support a maximum of 24 memory modules and up to 3TB of memory using Load-Reduced or Registered memory modules, or up to 6TB with four processors. Alternatively, a hybrid configuration will provide the maximum memory at up to 15.36TB using a mix of Intel Optane Data Center Persistent Memory Modules (DCPMM) and Load-Reduced memory modules. A four-processor configuration requires the addition of the Processor Expansion Module (PEM) that plugs into the motherboard right above the first processor and adds two more CPUs and 24 memory module slots. With four processors the system can support a maximum of 6TB of memory to address in-memory applications like SAP HANA. Administrators can install Registered (RDIMM), Load Reduced (LRDIMM), and 3DS LRDIMM modules running at frequencies of up to 2666MHz or 2933MHz depending on your choice of processors. Up to 12 NVDIMM modules can also be installed providing 192GB of non-volatile memory for data resiliency. NVDIMM modules must be paired with Registered DIMM modules only. The speed of the memory is determined by several factors including; memory speed, processor speed, speed settings in BIOS, and the operating voltage of the server.
