Dual-socket 1U platform for dense compute

The Dell PowerEdge R640 fits two Intel Xeon Gold 6148 processors, each with 20 cores at 2.4 GHz and a 3.7 GHz turbo frequency, into a single rack unit. It ships with 128 GB of DDR4 2666 MHz registered ECC memory across eight 16 GB modules, leaving 16 of the 24 DIMM slots free for expansion up to 3 TB. The system targets workloads that demand high core counts in a compact footprint.

Redundant power and flexible I/O in a hot-swap

Two 750 W platinum-efficiency power supplies provide N+1 redundancy with hot-swap replacement. The front panel holds eight 2.5-inch drive bays populated with 800 GB SATA SSDs driven by a PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. A quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ connections, while iDRAC 9 Enterprise enables full remote management. Rails and a front bezel are included for immediate rack mounting.

Verify rack depth, memory growth path

Confirm that your rack can accommodate the 1U height and that power distribution can deliver two 750 W feeds. Plan DDR4 registered ECC modules only; the 16 vacant slots support up to 3 TB total but require matched population rules. The SFP+ ports need compatible transceivers and cabling for 10 Gb links, and the PERC H730P battery should be checked for cache protection during unexpected power loss.

Questions sur cet article

What storage interface does the PERC H730P controller use, and what throughput does it cap at?

The PERC H730P is a 12 Gb/s SAS/SATA controller; installed drives are SATA 6 Gb/s SSDs, so the practical link speed is limited to 6 Gb/s per drive.

What rack space and mounting hardware does this 1U server require?

It occupies 1U of rack height and ships with ready rails for tool-less mounting in standard 4-post racks.

How are the CPUs and memory installed, and which step is often missed?

Both Xeon Gold 6148 processors are pre-installed in LGA 3647 sockets; the 128 GB DDR4 2666 MHz registered ECC DIMMs are already seated across the 24 slots — no further installation is needed.
