Server configuration

The Dell PowerEdge R640 is a 1U rack-mount server fitted with two Intel Xeon Bronze 3104 processors running at 1.7GHz and 768GB of DDR4 ECC registered memory. It targets organisations that need dense compute and large memory capacity for virtualisation, database or high-performance computing workloads in a standard rack environment. No storage drives are included, so buyers must supply their own 3.5-inch SATA drives.

Compatibility checklist

Verify that your rack provides 36 inches of depth, 24 inches of width and 10 inches of height (1U) for the chassis. The system uses a PERC H740P RAID controller with SATA drive interfaces and includes a 10GbE 2-port 562T network adapter. Two 750W power supplies are installed; confirm your PDU connectors and available power budget match this redundant supply design before ordering.

Thermal and power profile

Dual 750W power supplies share the load, providing redundancy while powering two 6-core CPUs and 768GB of memory. The 1U form factor uses high-speed internal fans to move air front-to-back; expect noticeable airflow noise typical of dense rack servers under load. Power draw will vary with CPU utilisation and the number of installed drives, but the redundant supply design helps maintain stable operation during normal use.

Questions about this item

Does the R640 arrive with any 3.5" drives or caddies, or must I source them separately?

The chassis provides four 3.5" bays and a PERC H740P controller, but no drives or caddies are installed; both must be purchased separately.

Should I select the 768 GB DDR4 configuration or plan to populate more slots later?

The system ships with 768 GB DDR4 ECC registered memory installed and supports up to 7.68 TB total, so additional modules can be added as workload demands grow.

What does the 1.7 GHz Xeon Bronze 3104 speed mean for typical server workloads?

Two 6-core Bronze 3104 CPUs at 1.7 GHz with 8.25 MB cache each deliver steady multi-threaded throughput for virtualization, database and file-serving tasks.
