Silver 1U rack server with eight front drive bays

DELL

DELL PowerEdge R640 1U rack server 2x Xeon Silver 4114 2.20GHz 20-core 128GB DDR4 8x 1.2TB SAS H740P 4x RJ45

SKU CH-7WPR-WACYM

1U rack server with two 10-core Xeon Silver 4114 CPUs at 2.20 GHz, 128 GB DDR4 ECC memory, eight 1.2 TB SAS drives on an H740P controller, and quad-port 1 GbE networking

  • Four 1 GbE RJ45 ports enable redundant network connectivity for business services

Dense virtualisation platform

The Dell EMC PowerEdge R640 packs two Xeon Silver 4114 processors into a 1U rack frame, delivering twenty cores at 2.20 GHz with turbo up to 3.50 GHz. One hundred and twenty-eight gigabytes of DDR4 ECC registered memory support heavy virtual machine counts and database workloads. Eight 1.2 TB SAS drives provide fast local storage for mixed business applications.

Redundant power and efficient airflow

Hot-swap redundant power supplies keep the server running during a module failure. The 1U chassis directs front-to-rear airflow across the processors and memory, maintaining stable temperatures under sustained load. Acoustic output stays within typical data-centre limits for dense rack deployments.

H740P controller and quad networking

The Perc H740P RAID controller with eight gigabytes of cache accelerates parity calculations and enables advanced array management without extra licensing. An integrated I350 quad-port 1 GbE controller supplies four RJ45 links for management, migration and storage traffic. Buyers needing 10 GbE or fibre-channel connectivity must add mezzanine cards separately.

Questions about this item

How do I install the Dell Perc H740P controller and what step is often missed?

Seat the H740P in the dedicated internal slot, connect the SAS cables to the backplane, then create the virtual disks in the controller BIOS before installing the OS.

Which components will need replacement first under continuous operation?

The eight 1.2TB 10K SAS drives and the hot-swap power supplies are the primary field-replaceable units that wear out first.

What thermal or power limit appears first during sustained 20-core workloads?

The 1U chassis airflow ceiling is reached before the dual Xeon Silver 4114 CPUs hit their maximum turbo frequency.
