Single-socket Xeon Gold 6248R server

The Dell PowerEdge R640 arrives as a 1U rack-mount system with one Intel Xeon Gold 6248R processor running at 3 GHz. Twenty-four cores and 35.75 MB of cache give the platform strong multi-threaded throughput for virtualisation, database and compute workloads. The chassis supports a second processor when demand grows.

PERC H740P RAID and 10 GbE networking

A Dell PERC H740P hardware RAID controller manages up to eight 2.5-inch SATA drive bays, providing data protection and performance tuning without consuming CPU cycles. An integrated dual-port 10 GbE 562T adapter delivers high-speed network connectivity for storage replication and cluster traffic. iDRAC9 Enterprise enables full remote power, console and firmware management.

256 GB DDR4 with 7.68 TB ceiling

Sixteen 16 GB DDR4 ECC registered modules populate the installed memory slots, delivering 256 GB of capacity for medium-scale virtualisation and in-memory databases. The platform scales to 7.68 TB when all DIMM slots are filled, giving ample headroom for future growth. Buyers who need immediate storage capacity or a second CPU must add those components separately.

Perguntas sobre este artigo

How much DDR4 memory can I add to the R640 before hitting the 7.68 TB ceiling?

The board supports up to 7.68 TB of DDR4 ECC registered memory; with 256 GB already installed there is headroom for additional modules.

Will the single Xeon Gold 6248R at 3 GHz become the bottleneck before the PERC H740P controller saturates?

The 24-core 6248R with 35.75 MB cache typically limits sustained compute throughput before the H740P RAID controller reaches its ceiling.

How loud and hot does the 1U chassis get when both 750 W supplies run continuously?

Dual 750 W supplies and high-density 24-core CPU push fan speeds up; expect noticeable airflow noise and warm exhaust in a 1U rack.
