High-density 2U storage server

The Dell PowerEdge R740xd2 is a 2U rackmount server built for data-intensive workloads that demand maximum internal capacity. It ships with two Intel Xeon Gold 6254 processors running at 3.1GHz with 18 cores each and 4.0GHz turbo frequency. The system includes 512GB of DDR4-2933 ECC registered memory across 16 slots and a Dell PERC H330 storage controller managing 26 enterprise-grade 8TB 7.2K SATA drives.

Suited for archive and backup workloads

This configuration targets organisations deploying software-defined storage, big data analytics, media archives or backup repositories where raw capacity and dual-socket compute density matter. The 26-bay 3.5-inch chassis and redundant 1100W platinum power supplies support continuous operation in standard racks. Buyers needing GPU compute, smaller form factors, or different drive interfaces should evaluate other platforms.

26-bay 3.5-inch SATA capacity

The single specification that determines fit is the front-loading 26-bay 3.5-inch SATA backplane paired with the H330 controller. It defines how many drives install, which drive protocol is native, and whether the chassis matches the rack space and cabling plan. Confirm the bay count, drive size and SATA interface against the deployment design before ordering.

Questions about this item

What does the 12Gb/s SAS/SATA PERC H330 controller cap the 26x 8TB SATA drives at in practice?

The PERC H330 controller runs at 12Gb/s SAS/SATA, so each 8TB 7.2K SATA drive is limited to the SATA 6Gb/s link speed.

What rack depth and rail kit does the 2U R740xd2 chassis require to fit 26x 3.5" drives?

The 2U chassis needs a four-post rack with enough depth for the 26-bay 3.5" front; ready rails are not included and must be sourced separately.

How are the two Xeon Gold 6254 processors and 16 DDR4-2933 DIMMs installed, and what step is often missed?

Both LGA 3647 CPUs seat in the two sockets first, then populate all 16 DIMM slots in the prescribed channel order; skipping the CPU-specific memory sequence is the common error.
