Server configuration

This Dell PowerEdge R640 arrives as a 1U rack server populated with one Xeon Gold 6244 processor running at 3.6 GHz and 256 GB of DDR4 ECC registered memory. The chassis provides four 3.5-inch large-form-factor drive bays wired to a Dell PERC H740P hardware RAID controller. Remote management is handled by iDRAC9 with an Enterprise licence, and dual 750 W power supplies are installed.

Suitable workloads

The single-socket design and 256 GB memory capacity suit virtualisation hosts, database nodes or application servers that fit within eight cores and do not require a second processor. Organisations needing more than 256 GB of RAM, dual-processor performance, or storage densities beyond four 3.5-inch bays should evaluate larger platforms.

Deciding specification

The installed memory ceiling of 256 GB across sixteen DIMM slots is the key limit; the platform can scale to 7.68 TB only when a second processor and additional modules are added.

Questions about this item

How do I install the 3.5 inch drives into the 4LFF chassis and which step is often missed?

Slide each drive into one of the four front bays until the latch clicks, then verify the PERC H740P RAID Controller detects every drive in the BIOS before loading the OS.

What maintenance or replacement will the 256GB DDR4 memory need later?

The sixteen 16GB DDR4 ECC Registered modules are rated for continuous server duty; plan to replace any stick that logs correctable errors in the iDRAC9 event log.

What limit appears first when the single Xeon Gold 6244 runs at 3.6 GHz under sustained load?

The dual 750W power supplies set the thermal ceiling; the CPU will throttle once the combined draw approaches the 750W per supply rating.
