Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rackmount server built for scale-out data centre workloads. Two Intel Xeon Gold 6134 processors run at 3.2 GHz with a 3.7 GHz turbo frequency. The system ships with 256 GB of DDR4 2666 MHz registered ECC memory across 24 slots. A PERC H730P controller manages two 400 GB SATA SSDs in the eight 2.5-inch drive bays.

Virtualisation hosts needing integrated 10 GbE

This configuration includes an Intel X520/I350 daughter card providing two 1 GbE and two 10 Gb SFP+ ports, suited to environments that want converged networking on the motherboard. Buyers who require additional PCIe expansion slots beyond the 1U form factor should consider a taller chassis. The 750 W redundant platinum power supplies support the installed components without extra headroom for high-power accelerators.

24 DDR4 slots define maximum memory

The R640 offers 24 DIMM slots with a 3 TB ceiling, so the installed 256 GB leaves ample room for growth. Memory must be DDR4 registered ECC; other generations or unbuffered modules are not compatible. Populate the remaining slots to match workload demands.

Questions about this item

How do I install the 2 x 400GB SATA SSDs into the 8-bay 2.5" chassis and what step is often missed?

Slide each drive into a front bay until the latch clicks, then use the PERC H730P BIOS utility to create a virtual disk before the OS sees the volume.

What maintenance will the PERC H730P 2GB controller battery need later?

The controller uses a 2GB battery-backed cache; plan to replace the battery module when iDRAC 9 Enterprise reports a degraded cache state.

What limit appears first when both Xeon Gold 6134 CPUs run at 3.7GHz Turbo under sustained load?

The 2 x 750W Platinum power supplies set the power envelope; prolonged all-core turbo can hit the supply limit before thermal throttling engages.
