Dual-socket Xeon Gold 6226 server

The Dell PowerEdge R640 ships with two Intel Xeon Gold 6226 processors running at 2.7 GHz. Each CPU provides 12 cores and 19.25 MB of cache. The system includes 32 GB of DDR4 ECC registered memory in a 16 GB x 2 configuration. It is aimed at organisations that need dense compute in a 1U rack footprint.

4-bay 3.5-inch chassis with PERC H740P

The 4LFF chassis accepts up to four 3.5-inch SATA drives, which are not installed in this configuration. A Dell PERC H740P RAID controller manages the storage array. Two 750 W power supplies and a 10 GbE dual-port 562T adapter are fitted. Remote management is handled by iDRAC9 with an Enterprise licence.

Sustained load on 24 cores and 32 GB RAM

Under continuous workloads the 24 combined cores share the installed 32 GB of DDR4 memory. The integrated graphics controller handles basic display output only. Memory capacity can be expanded to 7.68 TB when the application demands it. The dual power supplies maintain operation if one unit fails.

Questions about this item

Will the 2.7 GHz Xeon Gold 6226 CPUs throttle under continuous heavy compute loads?

The dual 12-core Xeon Gold 6226 processors run at a base 2.7 GHz; sustained all-core turbo depends on the cooling headroom inside the 1U chassis and the 750 W power supplies.

How loud are the fans and what is the typical power draw when the server runs 24/7?

Two 750 W supplies feed the system; fan speed ramps with CPU and PERC H740P controller temperature, so acoustics and wattage vary with the drives and workload you install.

Which drive trays and caddies do I need to populate the four 3.5-inch bays?

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