DELL PowerEdge R640 1U 2x Xeon Gold 6142 2.6GHz 16C 128GB DDR4 8x 2.4TB SAS H730P

Dual-Socket 1U Server Platform

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre computing. It ships with two Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores and a 3.7 GHz turbo frequency. The system includes 128 GB of DDR4 2666 MHz registered ECC memory across eight modules. Eight 2.4 TB 10K SAS drives and a PERC H730P RAID controller provide high-capacity local storage.

Compatibility and Expansion Checks

Verify that your rack provides standard 1U mounting space and that the included ready rails match your cabinet depth. Confirm the dual 750 W platinum power supplies connect to your available PDU outlets and voltage. The board offers 24 DDR4 slots with a 3 TB maximum, leaving 16 slots open for future memory growth. The X520/I350 daughter card delivers two 1 GbE and two 10 Gb SFP+ ports for network integration.

Sustained Load Behaviour

Redundant hot-swap power supplies and the H730P controller battery protect data integrity during extended write-heavy workloads. The 10K SAS drives maintain consistent throughput for mixed read-write patterns without the thermal throttling seen in burst-only benchmarks. iDRAC 9 Enterprise enables remote monitoring of temperatures, fan speeds and power draw so operators can balance density and cooling over long deployments.
