Dual-socket 1U rack server for dense compute

The Dell PowerEdge R640 packs two Intel Xeon Gold 6148 20-core processors running at 2.4 GHz with 3.7 GHz turbo into a single rack unit. It ships with 768 GB of DDR4 2666 MHz registered ECC memory across 24 slots and eight 2.4 TB 10K SAS drives on a PERC H730P 2 GB controller supporting RAID 0, 1, 5, 6, 10, 50 and 60.

Suits virtualization clusters and database nodes

This platform targets scale-out workloads that benefit from dual-socket performance in a 1U form factor. Buyers who need GPU acceleration or more than two processors should look elsewhere, as the chassis supports a maximum of two CPUs and has no GPU capability listed.

768 GB DDR4 2666 MHz ECC memory capacity

The installed 768 GB across 24 slots is the key figure for memory-bound applications. The system accepts up to 3 TB total, so workloads requiring larger in-memory datasets can expand within the same chassis.

Questions about this item

Will the 2.5-inch SAS bays and H730P controller work with my existing 12Gb/s SAS drives?

The chassis has eight 2.5-inch bays wired to the PERC H730P 2GB controller which supports 12Gb/s SAS and SATA, so your current 12Gb/s SAS drives will connect and operate at full speed.

How can I verify the dual Xeon Gold 6148 processors and 768GB DDR4 are recognised after installation?

Open iDRAC9 Enterprise or enter the BIOS; both will show two 20-core CPUs at 2.4GHz with 3.7GHz turbo and 768GB of 2666MHz registered ECC memory across all 24 slots.

Which items ship with the server and what must I purchase separately?

The unit includes the 1U chassis, bezel, ready rails, two 750W platinum power supplies, X520/I350 quad-port network card, H730P controller with battery, eight 2.4TB 10K SAS drives and 24x 32GB DDR4 modules; only an operating system licence and SFP+ transceivers for 10GbE ports are extra.
