DELL PowerEdge R740xd2 26 Bay 3.5" 2U Rack Server 2x Xeon Gold 6230 2.1GHz 20 Core 256GB DDR4 26x 4TB H330

High-capacity 2U rack server for data-intensive

The Dell PowerEdge R740xd2 is a 2U rackmount server built for environments that demand dense, high-capacity storage in a compact footprint. It targets software-defined storage clusters, big data analytics platforms, backup repositories and media archives where maximum drive count per rack unit is critical. Two Intel Xeon Gold 6230 processors deliver 40 total cores at 2.1 GHz with 3.9 GHz turbo for parallel throughput. 256 GB of DDR4-2666 ECC registered memory across eight 32 GB modules supports data integrity under sustained load.

Thermals noise and power in normal operation

Dual 1100 watt platinum-efficiency power supplies provide redundant hot-swap power for continuous availability. The 2U chassis uses front-to-rear airflow to cool 26 front-accessible 3.5-inch drives and dual CPUs within standard rack environmental limits. Fan speeds scale with inlet temperature and component load, keeping acoustic output consistent with typical data-centre rack density. Power draw varies with drive activity and CPU utilisation but remains within the redundant supply envelope for fail-safe operation.

Upgrades from lower-density

This configuration replaces 1U or 2U servers that max out at 12 to 16 drive bays, eliminating the need for external JBOD enclosures or additional rack units. It also supersedes single-socket systems limited to 20 cores and 1 TB memory capacity when workloads require dual-socket parallelism and full 256 GB installed RAM. The jump is justified when storage density, CPU core count and memory footprint must scale together inside a single 2U slot. Buyers needing fewer than 20 bays or a single processor should evaluate smaller platforms.
