Dense dual-socket compute

The PowerEdge R640 is a 1U rack server built for scale-out workloads. Two Xeon Gold 6148 processors provide 20 cores each at 2.4 GHz with a 3.7 GHz turbo frequency. 512 GB of DDR4 registered ECC memory fills 16 of the 24 available slots. Eight 600 GB 10K SAS drives connect through a PERC H730P controller with 2 GB cache.

Tool-less rails and hot-swap bays

Ready Rails allow the chassis to slide into a standard rack without tools. All eight 2.5-inch drive bays and both 750 W platinum power supplies support hot-swap replacement. The PERC H730P battery-backed cache protects in-flight writes during a power event. iDRAC 9 Enterprise gives full remote console access even when the operating system is down.

SAS 12 Gb/s bandwidth ceiling

The storage controller and drives operate at 12 Gb/s SAS, limiting sequential throughput to that link speed. RAID levels 0, 1, 5, 6, 10, 50 and 60 are supported, but the eight-bay count caps the maximum usable capacity and stripe width. Network connectivity uses two 1 GbE and two 10 GbE SFP+ ports on the daughter card. The two-socket maximum means CPU expansion stops at the installed pair.

Questions about this item

How do I confirm the PERC H730P controller and both Xeon Gold 6148 CPUs are detected after power-on?

Open the iDRAC9 Enterprise web interface or watch the POST screen; both 20-core Xeon Gold 6148 processors and the H730P with its 2GB cache battery should appear in the hardware inventory.

What ships inside the chassis and what must I purchase separately?

Included: 2× Xeon Gold 6148, 16× 32GB DDR4 2666MHz RDIMMs (512GB total), H730P controller, 8× 600GB 10K SAS drives, X520/I350 quad-port NIC, iDRAC9 Enterprise, 2× 750W PSUs, rails, bezel. Nothing else is required to run.

Which memory configuration matches the 512GB specification?

The system arrives with 16× 32GB DDR4 2666MHz registered ECC modules filling 16 of the 24 slots; this is the only capacity offered for this listing.
