2U Rack Server for Data-Intensive Workloads

The Dell PowerEdge R740xd2 is a 2U rackmount server built for storage-heavy applications such as software-defined storage, backup repositories and big data analytics. Dual Intel Xeon Gold 6254 processors deliver 36 total cores at 3.1 GHz with 4.0 GHz turbo capability. The system ships with 256 GB of DDR4-2933 ECC registered memory across eight 32 GB modules and 26 enterprise 8 TB 7.2K SAS drives.

Verify Rack Space, Power and Network Infrastructure

Confirm your rack provides 2U of clearance and that the facility can supply dual 1100 W power circuits for the redundant hot-swap supplies. Network connectivity uses an integrated dual-port 1 GbE LOM and a Broadcom 57414 dual-port 10/25 Gb SFP28 OCP 2.0 mezzanine card, so matching switch ports and cabling are required. The PERC HBA330 controller manages the 26 front-accessible 3.5-inch drive bays over 12 Gb/s SAS.

Enterprise Build With Front-Load Storage

Hot-swap drive bays and redundant power supplies allow drive or PSU replacement without downtime. The chassis uses 16 DDR4 slots, leaving eight free for future expansion up to 1 TB total capacity. iDRAC 9 Enterprise provides out-of-band remote monitoring and administration over a dedicated management port. Front bezel and ready rails are not included, so plan for separate rail kits and physical security if needed.

Questions about this item

What drives and accessories come with the R740xd2, and what is missing from the box?

The server includes 26 Dell Enterprise 8TB 7.2K SAS 3.5" drives, two 1100W Platinum PSUs, the HBA330 controller, an OCP 2.0 10/25Gb SFP28 mezzanine card, iDRAC 9 Enterprise, and a 1GbE LOM. Front bezel and Ready Rails are not included.

How do I choose between the installed 256GB DDR4 and the 1TB maximum capacity?

The system ships with 8x 32GB DDR4-2933 ECC RDIMMs filling 8 of 16 slots. Adding up to 8 more identical modules reaches 1TB; mixing capacities is possible but matched pairs per channel give best performance.

What does the 3.1GHz / 4.0GHz Turbo figure mean for real workloads on the dual Gold 6254 CPUs?

Each Gold 6254 runs at a 3.1GHz base clock across all 18 cores and can boost to 4.0GHz on fewer active cores, giving strong single-thread response while sustaining high multi-core throughput for database, virtualization, and analytics tasks.
