Dual-socket 1U server for dense compute

The PowerEdge R640 is a 1U rack server built around two Intel Xeon Silver 4116 processors running at 2.1 GHz with 12 cores each. It ships with 64 GB of DDR4 registered ECC memory across four 16 GB modules and a Dell PERC H730P controller with 2 GB cache. Eight 2.4 TB 10 K SAS drives fill the front bays, and dual 750 W platinum power supplies provide redundancy.

Suits scale-out workloads needing high core density

This configuration fits virtualisation clusters, database nodes and high-performance computing tasks that benefit from 24 total cores in a single rack unit. The quad-port network card delivers two 1 GbE and two 10 Gb SFP+ links, while iDRAC 9 Enterprise handles remote management. Buyers who need more than two processors, GPU expansion or storage beyond the eight 2.5-inch bays should evaluate other platforms.

Storage controller decides RAID flexibility

The PERC H730P supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode, backed by a battery-protected 2 GB cache. This determines which drive configurations are possible and how write performance behaves under load. Memory can grow to 3 TB across 24 slots, and the C620 chipset provides the I/O foundation.

Questions about this item

How do I install the PERC H730P controller and the eight 2.4 TB SAS drives in the 1U chassis, and what step is most often missed?

Mount the H730P in the dedicated internal slot, cable it to the backplane, then seat all eight 2.5 inch drives in the front bays; the step most often missed is enabling the controller battery in the BIOS before creating any RAID volume.

Which components will need replacement first during the server's life?

The eight 2.4 TB 10K SAS drives and the H730P controller battery are the primary wear items; the redundant 750 W platinum power supplies and system fans are hot-swap and also have finite lifespans.

What thermal or power limit appears first when both Xeon Silver 4116 CPUs run at sustained 3.0 GHz turbo?

The 1U form factor with dual 750 W PSUs and dense 2.5 inch drive layout means the chassis cooling capacity is reached before the 750 W power ceiling, causing CPU throttling under prolonged maximum turbo loads.
