Built for virtualisation and databases

The Dell PowerEdge R640 is a 1U rackmount server configured with dual Xeon Gold 6146 processors running at 3.20 GHz and 12 cores each. It ships with 96 GB of DDR4 memory and six 1 TB SSDs behind an H740P controller. The system targets file storage, virtualisation, database and application hosting workloads.

Front 2.5-inch bays and bezel included

Ten 2.5-inch drive bays sit behind a front bezel that gives the chassis a finished rack appearance. Standard front-panel LEDs show power, Ethernet and USB status for quick visual checks. The unit weighs 60 units and arrives tested with BIOS, controllers and storage arrays pre-configured.

Maximum memory capacity of 3 TB

The platform supports up to 3 TB of DDR4 when fully populated, letting the same chassis scale far beyond the installed 96 GB. Buyers who need more storage than six drives or who require GPU compute should evaluate other configurations.

Questions about this item

How do I install the 2.5" SSDs into the 10 front bays of the R640 and what step is commonly missed?

Slide each 2.5" drive into a carrier until it clicks, insert the carrier into a bay until the latch locks, then use the H740P controller BIOS or iDRAC to create the virtual disk before the OS sees the array.

What maintenance will the H740P RAID controller and its cache module need over time?

The H740P uses a flash-backed write cache; monitor the battery health LED in iDRAC and replace the cache module if the status shows degraded or failed to keep write performance consistent.

What thermal limit appears first when both Xeon Gold 6146 CPUs run at 3.20GHz under sustained load?

The 1U chassis airflow path reaches its cooling ceiling before the CPUs hit their maximum junction temperature, so fan speeds ramp to maximum and CPU clocks may throttle to stay within the thermal envelope.
