DELL PowerEdge C6525 Node EPYC 7402P 2.8GHz 24C 128GB DDR4 S150

Half-width rack node

The Dell PowerEdge C6525 node fits a half-width rack slot and runs a single AMD EPYC 7402P processor at 2.8GHz with 24 cores and 128MB cache. It ships with 128GB of DDR4 memory arranged as eight 16GB PC4-3200 modules. Remote management is handled by iDRAC9 Express and storage uses an S150 controller.

Sustained multi-threaded throughput

The 24-core EPYC 7402P maintains its 2.8GHz base clock across all cores, so prolonged compile jobs, database scans or virtualisation workloads keep steady throughput without the frequency drops seen in short-burst benchmarks. Eight-channel DDR4-3200 feeds each core pair with consistent bandwidth, reducing memory stalls during long runs. The S150 controller handles RAID duties without a dedicated cache, so sustained write rates depend on the attached drives rather than controller buffering.

Single 1GbE link and S150 RAID limits

Network traffic leaves the node through a single 1GbE LOM port, capping east-west cluster traffic and backup streams at gigabit speeds regardless of CPU headroom. The onboard S150 RAID controller supports only basic RAID levels and lacks a battery-backed cache, so write-heavy databases or log ingest should be directed to external storage or a hardware RAID upgrade. Memory capacity is fixed at 128GB across eight populated slots, leaving no room for expansion without replacing modules.
