High-capacity 2U rack server

The Dell PowerEdge R740xd2 is a 2U rack server built for data-intensive workloads that demand dense storage in a compact form factor. It targets environments such as software-defined storage clusters, big-data analytics platforms, backup repositories and media archives where capacity and reliability take priority over raw compute density.

Thermals, noise and power draw

Dual 1100 Watt platinum-efficiency power supplies provide redundant hot-swap power for continuous operation under heavy storage loads. The 2U chassis uses enterprise cooling tuned for twenty-six 3.5-inch drives and dual 18-core processors running at 3.0 GHz with 3.7 GHz turbo, so acoustic output and thermal load reflect a fully populated high-density configuration.

Bundled accessories and software impact

The PERC H730P controller with 2 GB cache enables RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through, giving administrators flexible data-protection options across the 26 installed 4 TB SAS drives. iDRAC 9 Enterprise delivers out-of-band remote management, monitoring and firmware updates without requiring an operating system, while the Broadcom 57414 dual-port 10/25 Gb SFP28 OCP 2.0 mezzanine card adds high-speed connectivity for storage fabrics. Front bezel and ready rails are not included, so rack-mounting hardware must be sourced separately.

Questions about this item

How do I install the 26x 4TB SAS drives into the 2U chassis, and which step is commonly missed?

Slide each 3.5" drive into the front bays until the carrier clicks; the step often missed is confirming the PERC H730P controller detects all 26 drives in the BIOS before creating virtual disks.

What maintenance or replacement will the PERC H730P 2GB cache battery need later?

The H730P includes a 2GB cache module with a battery-backed write cache; the battery typically requires replacement after 3–5 years to preserve cached data during power loss.

What thermal or power limit appears first when both Xeon Gold 6154 CPUs run at 3.7GHz Turbo under sustained load?

The 2x 1100W Platinum power supplies set the first hard limit; sustained 3.7GHz Turbo on 36 total cores can approach the PSU capacity before the 2U cooling reaches its maximum.
