Silver 1U rack server with 3.5 inch drive bays

DELL

DELL PowerEdge R660xs rack server QUO-25458444-F6W4Z1 Xeon Silver 4510 2.4G 12C/24T

SKU CH-XT7N-287ZX MPN QUO-25458444-F6W4Z1

1U rack server holds four 3.5" SATA drives and runs a 12-core Xeon Silver 4510 at 2.4 GHz with 24 threads and 30 MB cache

  • 5 inch chassis holds up to four SATA drives
  • Intel Xeon Silver 4510 delivers 12 cores and 24 threads at 2.4 GHz
  • 30 MB cache and 16 GT/s speed boost multi-threaded throughput
  • DDR5 memory runs at 5600 MT/s for high bandwidth
  • Dell Active Power Controller reduces energy use during low load

Purpose-built 1U server for single-socket workloads

The Dell PowerEdge R660xs is a 1U rack server configured with one Intel Xeon Silver 4510 processor running at 2.4 GHz with 12 cores and 24 threads. It targets environments that need compute density without a second CPU, such as web hosting, virtualisation clusters or departmental databases. Buyers who require dual-socket scale or more than four drive bays should look elsewhere.

Thermals, noise and power in normal use

A dedicated heatsink handles the 150 W TDP of the single Xeon Silver 4510, while Dell Active Power Controller adjusts power draw to match workload demand. The 1U chassis uses high-speed fans that ramp with inlet temperature, so acoustic output rises under sustained load. Typical operation stays within the thermal envelope defined for the 150 W CPU limit.

Build quality, connectors and daily implications

The 3.5-inch chassis holds up to four SATA hard drives and uses embedded SATA without a hardware RAID controller, so data protection relies on software RAID or external solutions. Memory runs at 5600 MT/s using DDR5 RDIMMs, and the system boots in UEFI mode with GPT partitioning. Single-CPU layout leaves the second socket empty, limiting future expansion to storage only.

Questions about this item

How do I install the Xeon Silver 4510 into the R660xs and which step is often missed?

Align the processor with the socket keying, lower the load plate, then torque the heatsink screws in a diagonal pattern to 11 in-lb; the step most often missed is the diagonal torque sequence.

What maintenance will the 3.5" SATA drives and 5600MT/s DDR5 RDIMMs need over time?

Plan to replace SATA drives after five years or when SMART alerts appear, and reseat DDR5 modules if correctable ECC errors rise above the platform threshold.

Which limit appears first when the 150W Xeon runs sustained workloads in the 1U chassis?

The 150W heatsink reaches its thermal capacity before the power supply or memory bandwidth becomes a bottleneck.
