Ideal workloads:

  • High-performance computing (HPC)
  • Analytics and big data
  • Web 2.0
  • Software-defined storage
  • Private cloud
  • Hyper-converged infrastructure

PowerEdge C6420 is ideal for high performance hyperscale workloads. With 4 nodes in a 2U form factor, it maximizes density, scalability, and energy efficiency per U.

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 Omnipath can be added for even higher scalability. This makes C6420 an ideal solution for hyperscale 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 with Lifecycle Controller and Redfish API for advanced management and scripting support.

Robust security spanning across the server ecosystem and life cycle

Every PowerEdge server is designed as part of a cyber-resilient architecture, integrating security into the full server life cycle. 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 designto retirement, Dell EMC ensures trust and delivers a worry-free, secure infrastructure without compromise.

  • Rely on built-in hardware root of trust and 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.
