High-density 2U storage server

The Dell PowerEdge R740xd2 is a 2U rackmount server built for data-intensive workloads that demand maximum storage density. Dual Intel Xeon Gold 6230 processors deliver 20 cores each at 2.1 GHz with 3.9 GHz turbo capability. 512 GB of DDR4-2666 ECC registered memory across 16 slots supports reliable operation for software-defined storage, backup repositories and media archives.

Storage controller and networking bundle

The PERC H330 controller manages 26 enterprise 4 TB 7.2K SATA 3.5" drives for high-capacity arrays. A dual-port 1 GbE LOM provides baseline connectivity while the Broadcom 57414 OCP 2.0 mezzanine card adds dual 10/25 Gb SFP28 ports for high-speed network fabrics. iDRAC 9 Enterprise enables comprehensive remote monitoring and administration without additional licensing.

Pre-deployment compatibility checks

Verify rack space for a 2U chassis and confirm power infrastructure can supply dual 1100 W platinum-efficiency supplies. Ensure SFP28 transceivers and cabling match the 10/25 Gb mezzanine ports for intended network topology. The front bezel and ready rails are not included, so plan for separate mounting hardware if required. Memory expansion beyond 512 GB requires DDR4-2666 ECC RDIMMs compatible with the 16-slot configuration.

Questions about this item

How many 3.5-inch drive bays remain open for future expansion after the 26 installed 4 TB drives?

All 26 front bays are occupied by the factory-installed 4 TB 7.2K SATA drives, so no 3.5-inch bays are free unless you remove existing drives.

Which component reaches its maximum rated capacity first when the server runs at sustained full load?

The two Xeon Gold 6230 processors hit their 20-core, 2.1 GHz base frequency limit before the 512 GB DDR4-2666 memory or the H330 controller saturate.

What is the typical acoustic and thermal output when both 1100 W platinum power supplies operate continuously?

Dual 1100 W platinum PSUs share the load, keeping each unit at moderate utilisation; the 2U chassis uses high-speed fans that produce noticeable but expected rack-level noise under sustained operation.
