Storage Density

The Dell PowerEdge R740xd2 is a 2U rack server built for data-intensive workloads that demand high-capacity internal storage. Dual Intel Xeon Gold 6230 processors deliver 40 total cores at 2.1 GHz with 3.9 GHz turbo, while 64 GB of DDR4-2666 ECC registered memory supports reliable operation. The PERC H330 controller manages up to 26 front-accessible 3.5-inch drive trays for SAS or SATA devices.

Ideal Workloads

This chassis suits software-defined storage clusters, backup repositories, media archives and big-data analytics where maximum 3.5-inch bay count in 2U is the priority. Buyers who need direct GPU compute, larger memory footprints beyond the installed 64 GB, or a higher count of low-latency flash slots should evaluate alternative platforms.

Deciding Specification

The defining attribute is the 26-bay 3.5-inch front layout combined with dual Xeon Gold 6230 CPUs and the H330 RAID controller, providing dense rotational or SSD storage under a single 2U rack unit.

Questions about this item

Does the server come with any drives installed or do I need to supply my own 3.5" SAS or SATA drives?

No drives are installed. The chassis includes 26 drive trays for 3.5" SAS or SATA drives that must be purchased separately.

How many memory slots are free for upgrading the 64 GB DDR4-2666 ECC RDIMM configuration?

Four of the 16 DDR4 slots are occupied by 16 GB modules, leaving 12 slots available for further expansion up to 1 TB.

What network throughput can I expect from the dual-port 10/25 GbE OCP 3.0 mezzanine card once the server is racked?

The Broadcom 57414 card provides two SFP28 ports each capable of 10 GbE or 25 GbE line rate depending on the transceiver and switch used.
