Dense 1U compute node

The Dell PowerEdge R640 fits two Xeon Gold 6246R processors and 768 GB of DDR4 ECC memory into a single rack unit. Four 3.5-inch drive bays and a PERC H740P RAID controller provide local storage flexibility while iDRAC9 Enterprise handles remote management. It ships without drives so you can populate the bays with the exact capacity and endurance you need.

Virtualisation and database hosts

This configuration suits workloads that demand high core counts and large memory footprints such as virtualisation clusters, in-memory databases or heavy application servers. Buyers who need GPU acceleration, more than four drive bays or a different processor generation should consider other platforms. The integrated graphics and 10 GbE dual-port adapter cover basic display and networking without extra cards.

Dual 16-core Xeon Gold 6246R at 3.4 GHz

The pair of 16-core processors running at 3.4 GHz with 35.75 MB cache each defines the compute ceiling for this server. Memory can scale to 7.68 TB of DDR4 when the workload grows beyond the installed 768 GB. Power is supplied by two 750 W units and the system measures 36 by 24 by 10 inches at 40 lb.

Preguntas sobre este artículo

How can I confirm the PERC H740P RAID controller and dual Xeon Gold 6246R CPUs are detected after power-on?

Open the iDRAC9 Enterprise web interface or watch the POST screen; both processors and the RAID controller appear in the system inventory with firmware versions listed.

Which components ship inside the 4LFF chassis and what must I add to make the server bootable?

The box contains the R640 4x3.5" chassis, two Xeon Gold 6246R processors, 768 GB DDR4 ECC registered memory, a PERC H740P RAID controller, a dual-port 10 GbE 562T adapter, two 750 W power supplies and rails on request; you must purchase 3.5" SATA drives separately.

With 768 GB already installed and a 7.68 TB maximum, which DDR4 modules should I buy to expand toward the limit?

Add DDR4 ECC registered DIMMs compatible with the Xeon Gold 6246R memory controllers; populate remaining slots in matched sets per channel to reach the 7.68 TB ceiling.
