Dense 1U dual-socket platform

The PowerEdge R640 packs two Intel Xeon Gold 6134 processors running at 3.2 GHz with a 3.7 GHz turbo into a single rack unit. Eight cores per CPU deliver 16 total threads for virtualised workloads, databases and high-performance computing clusters. It targets organisations that need maximum compute density without sacrificing memory capacity or storage performance.

Fits standard racks with redundant power

The 1U chassis occupies minimal rack height while providing 24 DDR4 slots, currently populated with 128 GB of 2666 MHz registered ECC memory and expandable to 3 TB. Dual 750 W platinum hot-swap supplies maintain uptime during a module failure. Eight 2.5-inch drive bays connect to a PERC H730P controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. A quad-port network daughter card adds two 1 GbE and two 10 Gb SFP+ links for flexible fabric integration.

Ready Rails and iDRAC9 Enterprise included

Sliding rails and a front bezel ship with the server so installation in a standard four-post rack requires no extra hardware. The iDRAC9 Enterprise licence enables full remote KVM, virtual media, telemetry streaming and automated firmware updates without an operating system. Eight 800 GB SATA SSDs are pre-installed, delivering high IOPS for boot, caching or mixed-read workloads straight from the factory.

Questions about this item

How many memory slots are available for future DDR4 upgrades beyond the 128GB installed?

The system provides 24 DDR4 slots in total; 8 are occupied by the factory 16GB modules, leaving 16 slots open for registered ECC memory up to the 3TB maximum.

What is the power draw and thermal load when both 750W Platinum supplies run at full capacity all day?

Dual 750W Platinum hot-swap units deliver redundant power; under sustained load they operate within Platinum efficiency targets, and the 1U chassis uses managed fan curves to keep inlet temperatures within ASHRAE guidelines.

Which cables and transceivers are needed to light the two 10Gb SFP+ ports on the X520/I350 daughter card?

The card presents two SFP+ cages; you must supply compatible 10Gb SFP+ transceivers or direct-attach cables and LC/MPO patch cords for the chosen fibre type.
