2U Server with 26-Bay 3.5" Storage

The Dell PowerEdge R740xd2 is a 2U rack server built for data-intensive workloads that demand high storage density. Two Intel Xeon Gold 6230 processors deliver 20 cores each at 2.1 GHz with 3.9 GHz turbo for multi-threaded performance. The platform suits software-defined storage, backup repositories and large-scale archives.

PERC H730P Controller and 25Gb Networking

The bundled PERC H730P mini controller provides 2 GB cache and supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through for 26 drive trays. A Broadcom 57414 dual-port 10/25Gb SFP28 OCP 2.0 mezzanine card adds high-speed connectivity alongside the integrated dual-port 1GbE LOM. iDRAC 9 Enterprise enables full remote management.

DDR4 Memory Limit and PCIe Constraints

Installed memory is 16 GB DDR4-2666 ECC registered across two modules with 16 total slots supporting up to 1 TB capacity. The LGA 3647 socket platform reaches its maximum with two processors already installed. Expansion depends on available PCIe slots not detailed here, and front bezel with ready rails are not included.

Questions about this item

What is the maximum DDR4 memory capacity this R740xd2 can take when I need to expand beyond the installed 16 GB?

The system supports up to 1 TB of DDR4 ECC registered memory across its 16 DIMM slots.

Which component will hit its limit first when the dual Xeon Gold 6230 processors run sustained heavy workloads?

The 1100 W platinum power supplies set the overall power envelope, capping sustained CPU turbo and total system draw before thermal limits are reached.

How much heat and noise should I expect from the redundant 1100 W supplies and 26 drive bays during continuous operation?

Dual platinum supplies run efficiently, but 26 spinning 3.5" drives plus two 20-core CPUs generate significant heat; the 2U chassis relies on high-speed fans that produce noticeable datacentre-level noise.
