Dense dual-socket 1U server

The PowerEdge R640 is a 1U rackmount server built around two Intel Xeon Silver 4116 processors, each with 12 cores running at 2.1 GHz. It ships with 768 GB of DDR4 memory across 24 slots and a PERC H730P controller driving two 800 GB SATA SSDs. This configuration targets dense scale-out workloads that need high core counts and fast storage in minimal rack space.

Redundant platinum power supplies

Dual 750-watt platinum-efficiency power supplies provide hot-swap redundancy so a single unit failure does not interrupt operation. The 1U chassis uses front-to-back airflow across the CPUs, memory and drive bays to keep thermals stable under sustained load. Fan speeds adjust automatically to balance cooling performance against acoustic output in the data centre.

Eight 2.5-inch bays and quad-port networking

The front panel holds eight 2.5-inch drive bays, leaving six empty slots for additional SATA or SAS devices behind the H730P controller. A daughter card adds two 1 GbE ports and two 10 Gb SFP+ ports for flexible network connectivity. iDRAC 9 Enterprise gives full remote management without consuming a PCIe slot, and ready rails with a front bezel simplify rack installation.

Questions about this item

How do I install the 24 DDR4 memory modules into the 24 slots, and which step is commonly missed?

Populate all 24 slots with the 32 GB registered ECC DDR4 modules at 2400 MHz; the step often missed is enabling the memory training sequence in the BIOS so the system recognises the full 768 GB capacity.

What maintenance will the PERC H730P storage controller need over time?

The controller uses a battery-backed 2 GB cache; plan to replace the battery module when the iDRAC 9 Enterprise alerts show degraded cache health to keep RAID 0, 1, 5, 6, 10, 50 or 60 performance intact.

Which limit appears first when both Xeon Silver 4116 CPUs run at 3.0 GHz turbo under sustained load?

The dual 750 W platinum power supplies set the thermal and current ceiling; sustained all-core turbo on 24 cores total will hit the power envelope before the CPUs reach their thermal throttle point.
