Up to 4x of these dual-socket, 15th generation, Dell PowerEdge C6520 Server nodes can be installed into the 2U Dell PowerEdge C6400 chassis. Each node supports 2x 3rd generation Intel Xeon Scalable CPUs with up to 40 cores, each. With 16x DDR4 DIMM slots on the system board it can be outfitted with up to 1TB of Registered DIMMs, or up to 2TB using Load-Reduced DIMMs. It supports several different PERC controllers providing access to either 3x or 6x up-front drive bays depending on if the C6400 chassis is configured with 12x 3.5-inch or 24x 2.5-inch drive bays.
Designed for applications in the cloud or data center, the Dell PowerEdge C6520 server offers a compute-dense platform that can provide up to 4x separate server nodes and up to 8x CPUs in a 2U C6400 chassis. It can also support High-performance computing (HPC) applications, plus web tech, and Everything as a Service, also known as XaaS a service provider. With 3rd generation Intel Xeon Scalable processors memory speed will run at up to 3200MT/s. CPUs with a TDP of up to 270W are supported and can provide up to 40 physical cores and 80 virtual threads using Platinum processors. 2x 24x bay backplane configurations. One configuration provides for all NVMe storage devices with no SAS or SATA support with 6x drives assigned to each sled. An alternate backplane configuration offers 16x – 20x SAS/SATA drives or one with 8x NVMs drives with each sled assigned 4x SAS/SATA and 2x NVMe drives. Lastly a 3.5-inch backplane supporting SAS, SATA, and NVMe drive formats with 3x drives assigned per node or a diskless no backplane model. The C620 chipset provides support to the PCIe single x8 slot that can be used for an M.2 SATA boot device to support the OS with 2x M.2 drives in mirror mode for redundancy, preserving the up-front drive bays.
4x PCIe 4.0 slots provide expansion options with three x16 slots, including an OCP 3.0 slot, and a single x8 slot for the M.2 boot device. The front of the C6400 chassis has an on/off button, which doubles as a status LED indicator. An information LED for each of the 4x nodes is located just below the power on/off button. Managing each Dell C6520 server sled is the integrated Dell Remote Access Controller or iDRAC 9.0 with LifeCycle Controller. iDRAC can be used to manage each sled individually through a standard browser window using the dedicated iDRAC RJ45 port on the back of the system. This system can also be managed in the data center using Dell’s OpenManage system management portfolio, which can manage groups of servers. Power is provided at the chassis level with support for dual PSUs up to 2600W. Direct contact liquid cooling (DCLC) is available.
