High-density 2U storage server

The Dell PowerEdge R740xd2 is a 2U rackmount server built for data-intensive workloads that demand maximum storage density in a compact footprint. It ships with two Intel Xeon Platinum 8260 processors running at 2.4 GHz with 3.9 GHz turbo, each delivering 24 cores for parallel compute tasks. The system includes 32 GB of DDR4-2933 ECC registered memory across 16 slots and a PERC HBA330 controller managing 26 front-accessible 3.5-inch drive bays populated with 8 TB 7.2K SATA drives.

Suited for archive and backup workloads

This configuration targets organisations running software-defined storage, big-data analytics, media archives or backup repositories that need high raw capacity and redundant 1100 W power supplies in 2U. Buyers who need faster flash storage, GPU acceleration, or a smaller rack footprint should evaluate alternative platforms. The included iDRAC 9 Enterprise licence and dual-port 10/25 GbE mezzanine card support remote management and high-throughput networking without extra purchases.

26-bay 3.5-inch chassis defines capacity

The single specification that decides fit is the 26-bay 3.5-inch front-loading chassis paired with the HBA330 controller, which sets the maximum number of mechanical drives and the SAS/SATA interface available for expansion. Memory can scale to 1 TB across 16 DDR4 slots and the dual LGA 3647 sockets are fully populated, so compute upgrades require processor replacement rather than addition.

Questions about this item

How many 3.5-inch drive bays does the R740xd2 chassis provide for the 26 installed 8 TB SATA drives?

The 2U chassis contains 26 front-accessible 3.5-inch bays, each populated with an 8 TB 7.2K SATA drive connected to the HBA330 controller.

Which slot does the Broadcom 57414 dual-port 10/25 Gb SFP28 OCP 2.0 mezzanine card occupy during installation?

The mezzanine card installs in the dedicated OCP 2.0 slot on the motherboard; the common error is seating it in a standard PCIe slot instead.

When the 32 GB of DDR4-2933 ECC RDIMMs must be expanded, how many additional memory slots are available?

The system has 16 total DDR4 slots with 4 occupied by the factory 8 GB modules, leaving 12 free slots for registered ECC DIMMs up to the 1 TB maximum.
