Dual-socket 1U rack platform

The PowerEdge R640 fits two Intel Xeon Silver 4116 processors into a single rack unit, delivering 24 cores at 2.1 GHz with 3.0 GHz turbo. It targets organisations running virtualised workloads, databases or high-performance computing clusters that need maximum compute density per rack slot.

Sustained multi-core throughput

With 64 GB of DDR4 2400 MHz registered ECC memory across four modules and 24 total DIMM slots supporting up to 3 TB, the system maintains consistent performance under continuous load. The PERC H730P controller with 2 GB cache handles RAID 0, 1, 5, 6, 10, 50 and 60 without write-hole risk during extended operations.

Redundant platinum power and remote management

Dual 750 W platinum-efficiency supplies share load and provide hot-swap failover. The Intel X520/I350 daughter card adds two 1 GbE and two 10 Gb SFP+ ports for flexible networking. iDRAC 9 Enterprise enables full out-of-band control, monitoring and firmware updates without host OS involvement.

Questions about this item

How loud and hot does the R640 get with both Xeon Silver 4116 CPUs running continuously?

The server uses redundant 750 watt platinum power supplies and a 1U chassis designed for data-centre airflow; actual acoustic and thermal output depend on the installed drives and ambient temperature.

Which drives and cabling do I need to add before the PERC H730P controller can present storage to the operating system?

The chassis includes eight 2.5-inch SAS/SATA trays but no drives; you must supply compatible SAS or SATA drives and the controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through.

Will my existing DDR4 registered ECC modules work in the 24 memory slots alongside the four 16-gigabyte sticks already installed?

The system arrives with 64 gigabytes in four slots running at 2400 megahertz; the remaining 20 slots accept additional DDR4 registered ECC modules up to the 3-terabyte maximum.
