Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores. The system includes 256 GB of DDR4 registered ECC memory across 24 slots. Redundant 750 W platinum power supplies and a front bezel with rails are included.

Suits virtualisation hosts needing maximum core

This configuration suits virtualisation hosts and compute clusters that need 32 total cores and 256 GB of DDR4 memory in a single rack unit. The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 2 GB cache. Buyers who need more than two processors or require 3.5-inch drive bays should look elsewhere.

256 GB DDR4 registered ECC memory across 24 DIMM

The installed 256 GB of DDR4 2666 MHz registered ECC memory occupies eight of the 24 available slots. This leaves 16 slots free for expansion up to the 3 TB maximum capacity. The memory type and slot count are the decisive factors when planning future upgrades or validating compatibility with existing modules.

Preguntas sobre este artículo

How long will the H730P controller battery last before it needs replacing?

The PERC H730P includes a 2 GB battery-backed cache; the battery typically lasts several years and can be swapped without removing the controller.

What limits sustained CPU performance in this 1U chassis?

Dual Xeon Gold 6142 processors share a 750 W redundant power budget, so thermal headroom in the 1U form factor is the first constraint under continuous load.

How loud and hot does the server get when running 24/7?

Redundant 750 W Platinum supplies and high-speed 1U fans keep components cool, but expect noticeable fan noise and warm exhaust air during all-day operation.
