High-Density 2U Rack Server

The Dell PowerEdge R740xd2 is a 2U rackmount server built for data-intensive workloads that demand high storage density. Dual Intel Xeon Gold 6154 processors provide 36 total cores at 3.0 GHz with 3.7 GHz turbo capability. The system ships with 512 GB of DDR4-2666 ECC registered memory across 16 populated slots. A PERC HBA330 controller manages up to 26 front-accessible 3.5-inch drive trays for massive SAS or SATA capacity.

Suited For Storage-First Deployments

This platform suits organisations building software-defined storage clusters, backup repositories, or media archives where drive count outweighs PCIe expansion. The 26-bay chassis and dual 1100 W platinum power supplies support dense, redundant storage configurations. Buyers who need more than two processor sockets or who require additional low-profile PCIe slots beyond the OCP 2.0 mezzanine should evaluate alternative chassis designs.

26-Bay 3.5-Inch Chassis Decides Fit

The defining specification is the 26-bay 3.5-inch front-drive layout combined with a 2U height. This density determines whether the server fits the planned rack space and delivers the raw drive count the workload requires. Verify that the SAS/SATA interface of the HBA330 matches the intended drive fleet before purchase.

Questions about this item

Should I pick the 18-core Xeon Gold 6154 or a lower-core option for this 2U server?

This configuration ships with two Xeon Gold 6154 processors, each 18 cores at 3.0GHz base and 3.7GHz turbo, filling both LGA 3647 sockets.

What does 512GB DDR4-2666 ECC registered memory mean for daily operation?

It provides 16 slots populated with 32GB modules, giving 512GB of error-correcting DDR4-2666 memory with headroom to 1TB maximum.

How does the PERC HBA330 12Gb/s SAS/SATA controller limit drive performance?

The HBA330 presents drives directly to the OS at up to 12Gb/s per SAS or SATA lane without RAID overhead.
