Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Silver 4110 processors running at 2.1 GHz with eight cores each. Sixty-four gigabytes of DDR4 registered ECC memory are installed across four 16 GB modules. Eight 2.4 TB 10K SAS drives connect through a PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. A quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ links. iDRAC 9 Enterprise and redundant 750 W platinum power supplies complete the package.

Suited for scale-out workloads

This configuration fits dense virtualization, database and high-performance computing clusters that need maximum compute in a single rack unit. The 24 DIMM slots and dual-socket design allow memory to grow to 3 TB when workloads demand it. Buyers who require more than two processors, additional PCIe slots for GPU or FPGA accelerators, or front-access 2.5‑inch bays beyond the eight provided should evaluate larger chassis alternatives.

24 DDR4 slots define memory ceiling

The system board offers 24 DDR4 registered ECC slots with a 3 TB maximum capacity. That slot count is the single specification that determines whether the platform can meet your memory footprint today and tomorrow.

Questions about this item

How often should I check or replace the PERC H730P controller battery?

The PERC H730P includes a 2GB cache battery that maintains data during power loss; Dell recommends checking battery health via iDRAC9 Enterprise every 12 months and replacing it when the status shows degraded capacity.

Which component reaches its thermal limit first when both Xeon Silver 4110 processors run at 3.0GHz Turbo continuously?

The dual 2.1GHz 8-core CPUs share the 1U chassis airflow; under sustained 3.0GHz Turbo load the processor package temperature typically hits the throttling threshold before the 750W platinum power supplies or memory modules do.

What is the typical power draw and fan noise level when the server runs 24/7 with all 8x 2.4TB SAS drives active?

With redundant 750W platinum supplies, idle draw is roughly 285W and rises toward 350W under full drive and CPU load; fan speed ramps to keep inlet temperature below 35°C, producing noticeable but datacentre-grade acoustic output.
