DELL PowerEdge R640 1U Rack Server 2x Xeon Gold 6142 2.6GHz 16C 128GB DDR4 H730P

Dual-socket 1U compute density

The PowerEdge R640 fits two Intel Xeon Gold 6142 processors into a single rack unit, each running at 2.6 GHz with 16 cores and a 3.7 GHz turbo frequency. Thirty-two total cores and 128 GB of DDR4 2666 MHz registered ECC memory provide a balanced foundation for virtualization clusters, database nodes or high-performance computing workloads that demand strong per-core performance in a compact footprint.

Sustained multi-threaded throughput

With both CPUs installed the system reaches its maximum processor count, allowing the Intel C620 chipset to manage memory across twenty-four DIMM slots up to a 3 TB ceiling. The PERC H730P controller with 2 GB cache and battery-backed write-back supports RAID 0, 1, 5, 6, 10, 50 and 60, maintaining consistent I/O latency during extended write-heavy operations. Redundant 750 W platinum power supplies share load continuously, preventing thermal throttling when all cores and drive bays are active.

Service-ready rack integration

Eight front-accessible 2.5-inch SAS/SATA trays accept hot-swap drives without tools, while the quad-port network daughter card delivers two 1 GbE and two 10 Gb SFP+ links for segmented traffic. iDRAC 9 Enterprise provides dedicated out-of-band management with virtual console and lifecycle automation. Ready Rails and a front bezel ship installed, enabling rapid deployment in standard four-post cabinets; the 1U height leaves no room for full-height PCIe cards, so expansion is limited to low-profile or mezzanine form factors.
