Dense 1U dual-socket server

The Dell PowerEdge R640 packs two Intel Xeon Silver 4116 processors, each with 12 cores running at 2.1 GHz and a 3.0 GHz turbo frequency. It ships with 128 GB of DDR4 registered ECC memory across eight 16 GB modules. The system is built for scale-out workloads that demand high compute density in a single rack unit.

Verify rack depth and network cabling

Confirm your cabinet can accept a 1U chassis with sliding rails and that front airflow matches the server's cooling design. The installed X520/I350 daughter card provides two 1 GbE and two 10 Gb SFP+ ports, so plan for compatible transceivers and switch ports. Ensure the PERC H730P controller's RAID levels meet your redundancy requirements before deployment.

Dual CPUs free memory slots for expansion

With both processor sockets populated, all 24 DIMM slots remain accessible for future growth up to the platform maximum. The H730P controller supports SAS and SATA drives across eight 2.5-inch bays, leaving six bays open for additional storage. Redundant 750 W power supplies and iDRAC9 Enterprise simplify ongoing management and uptime.

Questions about this item

Does the server ship with the 2× 800 GB SATA SSDs already installed, or do I need to purchase drives separately?

Two Dell Enterprise 800 GB SATA 6 Gb/s 2.5" SSDs come pre-installed in the eight-bay chassis, so no additional drives are required for basic operation.

Should I choose the 128 GB DDR4 configuration or plan for the 3 TB maximum?

The system arrives with 128 GB (eight 16 GB DDR4 2400 MHz registered ECC modules) filling 8 of 24 slots; you can add up to 3 TB later if workloads demand it.

What real-world throughput can I expect from the PERC H730P controller with the supplied SSDs?

The H730P 2 GB controller supports 12 Gb/s SAS/SATA and RAID 0/1/5/6/10/50/60; with the two 800 GB SATA SSDs you will see SATA 6 Gb/s sequential speeds limited by the drive interface.
