Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rackmount server fitted with two Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores and a 3.7 GHz turbo frequency. It ships with 512 GB of DDR4 2666 MHz registered ECC memory across 16 modules. The system targets dense scale-out data centre workloads that require high core counts in a single rack unit.

Thermals and power in normal use

Redundant hot-swap 750 W platinum-efficiency power supplies deliver power to the platform while maintaining uptime during a module failure. The 1U chassis uses integrated airflow management to cool both CPUs, memory and the PERC H730P storage controller under typical operating conditions. Idle noise remains contained within standard data centre limits for 1U density.

Behaviour under sustained load

Both processors can maintain elevated frequencies across all 32 combined cores when workloads saturate the available compute resources. The PERC H730P controller with 2 GB cache sustains RAID 0, 1, 5, 6, 10, 50 and 60 across eight 600 GB 10K SAS drives without thermal throttling. iDRAC 9 Enterprise provides continuous remote monitoring and management throughout extended heavy utilisation.

Vragen over dit artikel

How do I install the 2.5-inch SAS drives and what step is often missed?

Slide each 600 GB 10K SAS drive into the front hot-swap bays until the carrier clicks; the step people miss is creating the virtual disks in the PERC H730P BIOS before the OS sees any storage.

What maintenance or replacement will the server need later?

The PERC H730P RAID battery will eventually lose charge and should be replaced to keep write-back caching active; the 750 W platinum power supplies are hot-swap so a failed unit can be swapped without downtime.

What limit appears first under sustained heavy load?

The 750 W redundant power supplies set the sustained power ceiling; if both CPUs run at 3.7 GHz turbo continuously the system can hit that limit before thermal throttling occurs.
