Ideal server for high performance, hyperscale workloads The C6420 server supports dynamic business needs in scale-out environments where performance and density go hand in hand. The PowerEdge C6420 supports up to 4 dual socket compute nodes in a 2U form factor and with Direct Liquid Cooling options, supports high-wattage processors for even higher performance. Nonvolatile Memory express (NVMe) drives and fabrics such as InfiniBand and Omni Path can be added for even higher scalability. This makes C6420 an ideal solution for hyper-scale compute workloads requiring high scalability and high performance such as High Performance Computing (HPC), high-performance data analytics, financial modeling and high frequency trading, SaaS/IaaS and web-scale applications, visual effects rendering nodes, Hyper-Converged Infrastructure (HCI), Software Defined Storage, etc. Intuitive system management with intelligent automation With intelligent automation features, C6420 simplifies systems management and helps you free up precious IT skilled resources for business-critical activities. Designed for web-scale infrastructure, the C6420 does not forget management. Basic management is available with a base BMC option including a virtual console & virtual media. Optionally, leverage the integrated iDRAC9 and Redfish API for advanced management and scripting support. Robust security spanning across the server ecosystem and lifecycle Every PowerEdge server is designed as part of a cyber resilient architecture, integrating security into the full server lifecyle. The C6420 leverages new security features built-into every new PowerEdge server strengthening protection so you can reliably and securely deliver accurate data to your customers no matter where they are. By considering each aspect of system security, from design to retirement, Dell EMC ensures trust and delivers a worry-free, secure infrastructure without compromise. Rely on a secure component supply chain to ensure protection from factory to the data center. Maintain data safety with cryptographically signed firmware packages and Secure Boot. Protect your server from malicious malware with iDRAC9 Server Lockdown mode (requires Enterprise or Datacenter license). Wipe all data from storage media including hard drives, SSDs and system memory quickly and securely with System Erase.

This OCP slot is a dedicated slot just for these types of cards. These OCP slots provide an excellent way to add networking capabilities to the node server. Storage Controllers Each Sled has access to a certain number of drives on the C6400 Rack server. To save a drive from being the boot drive. You can install an M.2 BOSS riser or place a Micro SD card in the primary optional riser. The BOSS riser has a dedicated slot and can hold up to 1x M.2 NVMe SSDs per node. These two options are great for Booting the OS. Please read the manual for more details on this subject.
