Rack server for dense compute

The Dell PowerEdge R640 delivers a 1U rack-mount platform with a single Xeon Gold 5218 processor at 2.3 GHz and 16 cores. It ships with 256 GB of DDR4 ECC registered memory across 16 DIMM slots, leaving headroom to reach the 7.68 TB maximum. The chassis provides four 3.5-inch drive bays and a PERC H740P RAID controller, while a 10 GbE 2-port 562T adapter handles network traffic. iDRAC9 Enterprise enables full remote management.

Sustained load with dual 750 W supplies

Dual 750 W power supplies share the load and provide redundancy during continuous operation. The 16-core CPU maintains its 2.3 GHz base frequency under extended multi-threaded workloads, supported by the large 22 MB cache. DDR4 ECC memory corrects single-bit errors in real time, preventing data corruption during long-running jobs. The PERC H740P controller offloads RAID parity calculations, keeping storage throughput stable when all four bays are populated.

Slide rails and cabling need planning

The server includes mounting rails on request, but the 36-inch depth requires a rack with sufficient clearance for cable routing at the rear. Drive carriers for the 3.5-inch bays must be ordered separately if not already on hand. Memory population follows specific channel rules; incorrect DIMM placement reduces bandwidth or prevents boot. The iDRAC9 Enterprise licence is pre-activated, yet initial network configuration still requires console access or a dedicated management LAN.

Spurningar um þessa vöru

How much power does the dual 750W supply arrangement draw when the Xeon Gold 5218 runs at full load all day?

The system ships with two 750W power supplies; actual draw depends on workload and drive population, so monitor iDRAC9 readings for real-time consumption.

Which drive trays and caddies must I already have to populate the four 3.5-inch bays?

The 4LFF chassis accepts standard Dell 3.5-inch hot-plug trays; drives themselves are not included and must be supplied separately.

Will my existing SATA drives work with the PERC H740P controller in this R640?

Yes, the H740P supports SATA drives in the four 3.5-inch bays, allowing you to reuse compatible drives you already own.
