DELL
2U rack server with dual Xeon Gold 6254 18-core processors, 256GB DDR4, and 26 4TB SATA drives
The Dell PowerEdge R740xd2 is a 2U rackmount server system built for data-intensive workloads. It ships with two Intel Xeon Gold 6254 processors running at 3.1 GHz with 4.0 GHz Turbo, 18 cores each, and 256 GB of DDR4-2933 ECC registered memory. Twenty-six 4 TB 7.2K SATA 3.5-inch hard drives provide high-capacity storage managed by a Dell PERC H330 controller. Redundant 1100 W platinum power supplies and iDRAC 9 Enterprise remote management support continuous operation.
This platform suits organisations deploying software-defined storage, big data analytics, backup repositories or media archives that demand dense 3.5-inch drive capacity in a 2U form factor. Buyers who require a smaller rack footprint, fewer drive bays or a different drive interface should evaluate other platforms. The server arrives without a front bezel or ready rails, so those accessories must be sourced separately if needed.
The defining specification is the 26-bay 3.5-inch chassis populated with 4 TB 7.2K SATA drives delivering over 100 TB of raw storage in a single 2U unit. This density determines whether the system fits a workload that prioritises maximum spinning-disk capacity over flash speed or a smaller physical profile.

The server occupies a standard 2U rack height and uses Dell Ready Rails for installation; the rails are not included with this unit.
Drives slide into the front hot-swap bays on the PERC H330 controller; the common oversight is forgetting to create virtual disks in the controller BIOS before the OS sees the volumes.
The redundant 1100 W PSUs are hot-swap and typically last several years; DDR4-2933 ECC RDIMMs should be replaced only if a module fails or capacity must exceed the current 256 GB across the 16 slots.
