Dual-socket 1U rack server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data center computing. It ships with two Intel Xeon Silver 4116 processors, each running at 2.1 GHz with 12 cores. The system includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules and eight 800 GB SATA SSDs. A PERC H730P controller and iDRAC9 Enterprise provide storage and remote management capabilities.

Suited for virtualisation and scale-out workloads

This configuration fits environments that need high core counts and redundant power in a single rack unit. The dual 750 W platinum supplies and hot-swap drive bays support continuous operation. Buyers who need more than two processors, larger memory capacity than 256 GB, or GPU-accelerated compute should look at other platforms.

PERC H730P with 2 GB cache

The storage controller determines RAID flexibility and drive performance. The installed H730P supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through with a 2 GB battery-backed cache. This decides whether the server matches your storage redundancy and throughput requirements.

Questions about this item

When will the H730P controller battery need replacement to keep RAID cache protected?

The PERC H730P includes a 2 GB battery-backed cache; plan to swap the battery module every three to five years so write-back caching stays safe during power loss.

What thermal limit appears first when both Xeon Silver 4116 CPUs sustain full turbo?

Each processor can reach 3.0 GHz turbo, but the 1U chassis and dual 750 W power supplies set the practical ceiling — fans will ramp to maximum before the CPUs throttle.

How loud and hot does the rack unit get with both 750 W PSUs loaded all day?

Redundant platinum supplies share the load, keeping each below 50 %; expect noticeable fan noise in a quiet room and exhaust air warm enough to require proper aisle containment.
