Dual-Socket 1U Server Platform

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data center computing. Two Intel Xeon Platinum 8160 processors provide 24 cores each at 2.1 GHz with 3.7 GHz turbo. The system includes 128 GB of DDR4 2666 MHz registered ECC memory across eight modules. Eight 2.4 TB 10K SAS drives connect through a PERC H730P controller with 2 GB cache.

Suited For And Limits

This configuration suits workloads that demand high core counts and fast local storage in a single rack unit. The quad-port network daughter card offers two 1 GbE and two 10 Gb SFP+ connections for flexible fabric integration. Buyers who need more than 3 TB of memory capacity or more than two processors should evaluate larger platforms. The 2.5-inch drive bays limit total drive count to eight without external enclosures.

Maximum Memory Capacity Decides Fit

The Intel C620 chipset supports up to 3 TB of DDR4 across 24 DIMM slots, so the installed 128 GB leaves substantial headroom for future expansion. The PERC H730P handles RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through modes for diverse storage topologies. Redundant 750 W platinum power supplies and iDRAC 9 Enterprise remote management complete the enterprise feature set.

Questions about this item

What comes with the server and what must be purchased separately?

The system ships with two Xeon Platinum 8160 processors, 128GB DDR4 in eight 16GB modules, a PERC H730P controller with battery, eight 2.4TB SAS drives, a quad-port X520/I350 network card, iDRAC9 Enterprise, two 750W PSUs, rails and a front bezel.

Which memory configuration should I choose for this R640?

The installed 128GB uses eight 16GB DDR4 2666MHz Registered ECC DIMMs across the 24 available slots, leaving 16 slots open for expansion up to the 3TB maximum.

What does the 3.7GHz turbo figure mean in daily use?

The 3.7GHz turbo is the maximum single-core frequency each 24-core Xeon Platinum 8160 can reach under thermal and power headroom; sustained all-core speeds will sit at the 2.1GHz base clock.
