Dell PowerEdge C4140 Technical Guide

The Dell EMC PowerEdge C4140 is a purpose-built 1U rack server designed by Dell EMC to deliver high-density performance for demanding technical computing and GPU-accelerated workloads within heterogeneous data center environments. This model supports two second-generation Intel Xeon Scalable processors, offering configurations with up to 24 cores per socket, and accommodates up to four double-width NVIDIA Tesla accelerators or FPGAs in just one rack unit, enabling organizations to maximize compute power while minimizing space, cost, and management overhead. The PowerEdge C4140 fills a critical gap in the PowerEdge portfolio by providing a scalable platform that integrates advanced accelerator technologies with robust processing capabilities for high-performance computing tasks.

Technical specifications for the Dell EMC PowerEdge C4140 include support for up to 24 DDR4 DIMMs reaching a maximum capacity of 1.5 TB at speeds up to 2933 MT/s using RDIMMs and LRDIMMs. Storage options center on an internal BOSS PCIe card with M.2 SD drives for boot volumes, available in 120 GB, 240 GB, or 480 GB configurations, alongside optional IDSDM modules and rear PCIe Gen3 low-profile slots for NVMe SSD accelerator interface cards. The system features four dedicated double-width PCIe Gen3 x16 slots for GPUs and two additional low-profile rear expansion slots, while network connectivity is handled via Intel Network Daughter Cards supporting 10 GbE BT or SFP+ interfaces, along with various optional dual-port adapters for flexible fabric integration.

Power delivery for the Dell EMC PowerEdge C4140 is managed through hot-plug platinum efficiency power supplies rated at 2000 W or 2400 W in redundant or single configurations. The server emphasizes security and management with embedded iDRAC9 featuring Lifecycle Controller for hardware inventory, alerting, and remote administration, complemented by enterprise management consoles like OpenManage Enterprise. Security features include TPM 1.2 or 2.0 support, cryptographically signed firmware, Silicon Root of Trust, and Secure Boot to protect the infrastructure. Buyers seeking a compact, efficient solution for AI inference, machine learning, and complex analytics will find the PowerEdge C4140 addresses these needs by delivering maximum accelerator density and thermal efficiency in a footprint that reduces total cost of ownership compared to multi-server arrangements.
