Dual-Socket 1U Rack Server

The Dell PowerEdge R640 is a 1U rack-mount server system built for dense scale-out data centre computing. It ships with two Intel Xeon Platinum 8160 processors, each running at 2.1 GHz with 24 cores. The system includes 512 GB of DDR4 2666 MHz registered ECC memory across 16 DIMM slots and is powered by redundant 750 W platinum-efficiency power supplies.

Suited For Virtualisation And Heavy Compute

This configuration suits buyers who need high core counts and large memory capacity in a single rack unit for virtualisation, database or high-performance computing workloads. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections, and iDRAC 9 Enterprise enables full remote management. Builders who require GPU acceleration or more than eight drive bays should look elsewhere, as the 1U chassis does not support those additions.

2.4 TB SAS Drives With H730P RAID

Eight 2.4 TB 10K SAS hard drives connect to the PERC H730P 2 GB controller, which supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes. The 12 Gb/s SAS interface delivers consistent throughput for transaction-heavy applications. Buyers who need solid-state storage or a different drive capacity will need to reconfigure the storage subsystem.

Questions about this item

How do I install the eight 2.5-inch SAS drives and the PERC H730P controller, and what step is often missed?

Mount each drive in a hot-swap tray, slide it into the front bays until it locks, and seat the H730P in its dedicated internal slot; the step often missed is enabling the controller battery in the BIOS so write-back caching activates.

What maintenance will the PERC H730P battery and the 750W power supplies need later?

The H730P battery typically lasts three to five years and should be replaced when iDRAC reports a degradation alert; each 750W supply is hot-swappable, so a failed unit can be pulled and replaced without shutting down the server.

Which limit appears first when both Xeon Platinum 8160 CPUs run at 3.7GHz turbo under sustained load?

The 1U chassis cooling capacity is the first limit; the dual 750W platinum power supplies and 512GB DDR4 memory headroom remain within specification while the thermal envelope constrains prolonged turbo operation.
