Dell PowerEdge C6400 2U rack server

This Dell PowerEdge C6400 is a 2U rack server populated with one C6525 compute node. The node carries two AMD EPYC 7502 processors running at 2.5GHz with 32 cores each and 128M cache. It ships with 32GB of DDR4 memory in a 2x 16GB PC4-3200 configuration. The chassis provides 24 bays for 2.5-inch drives and includes a 1600W redundant power supply.

Buyers needing dense multi-node compute

This configuration suits buyers who need a single high-core-count node in a shared 2U chassis that can accept up to four nodes. The 64 total cores and PCIe Gen4 x16 low-profile slot support GPU or accelerator workloads. iDRAC9 Express handles remote management. Builders who require more than one node, more than 32GB of memory, or storage trays and drives included should look at a different configuration.

64 cores from two EPYC 7502 CPUs

The defining specification is the pair of EPYC 7502 processors delivering 64 cores at 2.5GHz. This core count drives virtualisation density, HPC throughput and licensed-software economics. If the workload needs fewer cores or a different memory capacity, another node or server will fit better.

Questions about this item

How do I install the C6525 node into the C6400 chassis and what step is often missed?

Slide the node into the 2U chassis until the latch clicks, then secure the retention screws; the step often missed is re-engaging the internal power and data connectors at the mid-plane before powering on.

What maintenance will the 1600W redundant power supply need later?

The hot-swap PSUs can be replaced individually without downtime; plan to swap a unit if the iDRAC9 Express logs a fan-speed or voltage warning.

What limit appears first when both EPYC 7502 CPUs run sustained workloads?

The 32 GB DDR4-3200 memory (2×16 GB) fills quickly, so capacity becomes the bottleneck before the 32-core processors or the single PCIe Gen4 x16 slot saturate.
