Dense 1U Dual-Socket Server

The Dell PowerEdge R640 is a 1U rack-mount server fitted with two Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores. It ships with 256 GB of DDR4 registered ECC memory across eight 32 GB modules. Eight 300 GB 10K SAS drives connect to a PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60.

Virtualisation Hosts and Scale-Out Workloads

This configuration suits virtualisation clusters, database nodes and high-performance computing tasks that demand high core counts in a single rack unit. Buyers who need more than eight 2.5-inch drive bays, additional PCIe expansion slots or GPU compute density should evaluate larger chassis options.

Dual Gold 6142 at 2.6 GHz with 16 Cores Each

The two Xeon Gold 6142 CPUs provide 32 total cores and a 3.7 GHz turbo frequency, setting the performance ceiling for heavily threaded applications. Memory capacity can grow to 3 TB across 24 DDR4 slots when workloads outgrow the installed 256 GB.

Questions about this item

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

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

Which component reaches its thermal limit first when both Xeon Gold 6142 CPUs run at 3.7GHz turbo continuously?

The dual 16-core Xeon Gold 6142 processors will hit their thermal ceiling before the 750W platinum power supplies or the 256GB DDR4 memory.

How loud are the fans and how much power does the server draw under 24/7 load with all eight 300GB SAS drives active?

Expect elevated fan noise in the 1U chassis and a sustained draw near the 750W redundant PSU capacity when both CPUs and all drives run continuously.
