Dense compute in a 1U chassis

The Dell PowerEdge R640 fits two Xeon Gold 5218R processors and 768 GB of DDR4 ECC registered memory into a single rack unit. Four 3.5-inch drive bays and a PERC H740P RAID controller provide local storage flexibility. Integrated 10 GbE networking and iDRAC9 Enterprise remote management suit virtualisation clusters and database workloads.

Steady throughput with dual 20-core CPUs

Under sustained load the 40 combined cores at 2.1 GHz maintain consistent frequency thanks to the 1U airflow design and dual 750 W power supplies. The H740P controller sustains write performance across RAID sets without throttling. iDRAC9 telemetry lets operators monitor thermals and power draw continuously during long-running jobs.

SATA interface caps drive speed at 6 Gb/s

The four 3.5-inch bays connect through SATA, limiting each drive to the 6 Gb/s link rate regardless of media capability. PERC H740P RAID spans or mirrors those drives but cannot exceed the bus ceiling. Maximum memory capacity reaches 7.68 TB when all DIMM slots are populated with supported DDR4 modules.

Questions about this item

How much power do the two 750 W supplies draw when the dual 2.1 GHz Xeon Gold 5218R processors run continuously?

Each power supply is rated at 750 W; the pair provides redundancy so the system stays on if one unit fails.

Which storage drives must I supply myself to use the four 3.5-inch bays and the PERC H740P controller?

The chassis has four 3.5-inch bays wired to the PERC H740P RAID controller; you add SATA hard drives or SSDs of your choice.

Will my existing SATA drives work with the PERC H740P controller in this R640?

Yes, the PERC H740P supports SATA drives, so any 3.5-inch SATA HDD or SSD you already own can be installed in the four bays.
