Dense compute platform

The Dell PowerEdge R640 is a 1U rack server fitted with two Xeon Silver 4110 processors running at 2.1GHz and 1TB of DDR4 ECC registered memory. It provides 10 front-accessible 2.5-inch drive bays backed by a PERC H740P RAID controller and includes iDRAC9 Enterprise for remote management.

Virtualisation hosts needing maximum memory per

The configuration suits clusters that prioritise memory capacity over local storage density. Buyers who require pre-installed drives, GPU acceleration or a smaller chassis should look elsewhere.

1TB DDR4 installed with 7.68TB maximum

The system ships with 1TB of DDR4 ECC registered memory across 24 slots and can scale to 7.68TB. Memory type and maximum capacity are the decisive figures for compatibility planning.

Questions about this item

Will the PERC H740P controller become a bottleneck when all ten 2.5" bays are filled with SATA drives?

The PERC H740P RAID controller manages the ten 2.5" drive bays through the SATA interface, so its throughput and queue depth set the sustained I/O ceiling when the chassis is fully populated.

How much heat and fan noise should I expect from the dual 750W supplies and two 2.1GHz Xeon 4110 CPUs running 24/7?

Dual 750W power supplies and two Xeon Silver 4110 processors at 2.1GHz draw continuous power, so the system fans ramp up to keep the 1U chassis within thermal limits, producing noticeable airflow noise in a quiet room.

Which rail kit matches the 36 x 24 x 10 in dimensions so the server slides into my rack?

The chassis measures 36 x 24 x 10 in and the supplier notes a rail kit is available on request, so you need the Dell sliding rails built for the R640 1U form factor to mount it securely.
