Dense storage server

The Dell PowerEdge R740xd2 is a 2U rack server built for data-intensive workloads that demand high capacity in a compact footprint. Two Intel Xeon Gold 6254 processors deliver 36 cores at 3.1 GHz with 4.0 GHz turbo. The system ships with 256 GB of DDR4-2933 ECC registered memory across 16 slots and a PERC H330 controller managing 26 installed 8 TB 7.2K SATA drives. Dual 1100 W platinum supplies provide redundant power.

Suited for capacity-first deployments

This configuration targets software-defined storage, backup repositories, big-data analytics and media archives where raw capacity and drive density outweigh raw compute speed. The 26-bay 3.5-inch chassis and dual 10/25 GbE mezzanine card support high-throughput ingest. Buyers who need faster flash performance, GPU acceleration or a smaller form factor should evaluate other platforms.

26-bay 3.5-inch SATA capacity

The single specification that decides fit is the 26-bay 3.5-inch SATA layout paired with the PERC H330 controller. It fixes the storage protocol to SATA and the drive count to 26, so any environment that requires a different interface, a different bay count or a different controller must choose a different server.

Questions about this item

What does having two Xeon Gold 6254 CPUs at 3.1 GHz with 18 cores each actually deliver in this server?

The dual-socket configuration provides 36 physical cores running at a 3.1 GHz base clock with 4.0 GHz turbo capability, giving the system high multi-threaded throughput for virtualization, database, and analytics workloads.

What storage throughput does the PERC H330 controller and SATA interface limit these 26 drives to in practice?

The H330 controller operates at 12 Gb/s SAS/SATA, but the installed 7.2K SATA drives and SATA 6 Gb/s interface cap sustained sequential throughput to the drive media speed, typically well below the controller ceiling.

What physical space and mounting hardware does a 2U chassis with 26 front 3.5" bays require?

The server occupies 2U of rack height and uses standard square-hole mounting; the front bezel and ready rails are not included, so you must supply compatible sliding rails for installation.
