Dual Xeon Gold 6226 Server

The Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Gold 6226 processors running at 2.7 GHz. Each CPU provides 12 cores and 19.25 MB cache for multi-threaded workloads. The system ships with 384 GB of DDR4 ECC registered memory installed. It is aimed at organisations that need dense compute in a standard rack footprint.

384 GB DDR4 Memory Capacity

The single specification that decides fit is the 384 GB of DDR4 ECC registered memory already populated across the DIMM slots. The board supports a maximum of 7.68 TB, so further expansion is possible if the application demands it. Buyers who need a different memory configuration must request a custom build before purchase.

Sustained Load Behaviour

Dual 750 W power supplies and the integrated iDRAC9 Enterprise remote management keep the platform stable during extended compute runs. The PERC H740P RAID controller manages up to four 3.5-inch SATA drive bays for local storage redundancy. The 10 GbE 2-port 562T adapter maintains network throughput without thermal throttling under continuous traffic.

Questions about this item

What does 384 GB of DDR4 memory mean for workloads running on this R640?

The system ships with 384 GB of DDR4 ECC registered RAM across two Xeon Gold 6226 processors, giving ample capacity for virtualization, databases or in-memory analytics without swapping.

How does the PERC H740P controller and SATA interface limit drive performance in the 4-bay 3.5-inch chassis?

The H740P RAID controller manages up to four 3.5-inch SATA drives; the SATA link caps each drive at 6 Gb/s, so sustained throughput is bounded by the mechanical disks rather than the controller.

Will the 36 x 24 x 10 inch rack-mount chassis fit a standard 19-inch cabinet and what rails are required?

The 1U rack-mount form factor fits a standard 19-inch cabinet; sliding rail kits are available on request to secure the 40 lb unit in the rack.
