  2. Dell EMC PowerEdge C6520 Sled CTO
  3. Dell EMC PowerEdge C6525 Sled CTO

    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 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.
