Dual-socket 1U server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre workloads. It ships with two Intel Xeon Gold 6142 processors running at 2.6 GHz, each offering 16 cores and a 3.7 GHz turbo frequency. The system includes 768 GB of DDR4-2666 registered ECC memory across all 24 DIMM slots.

Suits virtualisation hosts needing maximum core

This configuration targets environments that prioritise core count and memory capacity within a single rack unit. The dual 16-core CPUs and 768 GB DDR4 support heavy virtual machine consolidation or in-memory databases. Buyers who need more than two processors, solid-state drives, or a different drive-count layout should look at alternative platforms.

PERC H730P controller

Storage is handled by a Dell PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes. Eight 2.5-inch 2.4 TB 10K SAS hard drives are installed, providing high-capacity rotational storage. The controller and drive set define the storage performance and redundancy options available.

Questions about this item

What rack height and rail kit does the 1U R640 require?

The server occupies 1U of rack space and ships with Ready Rails for tool-less mounting in standard four-post racks.

How are the 24 DDR4 DIMMs and two Xeon Gold 6142 processors installed, and what step is often missed?

Populate all 24 slots with 32 GB registered ECC modules across both CPU sockets; the step often missed is enabling the memory training sequence in the BIOS after first boot.

Which components will need replacement first — the PERC H730P battery or the 2.4 TB SAS drives?

The RAID controller battery typically reaches end of life after 3–5 years, while the 10 K SAS drives are rated for a 2.5 million-hour MTBF.
