Dense storage server for virtualised workloads

The Dell PowerEdge R740xd is a 2U rack system with two Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores. It ships with 64 GB of DDR4 registered ECC memory across four modules. Twenty-four 2.5-inch SAS/SATA drive trays provide high-density local storage for software-defined storage or VDI deployments.

Verify rack depth, power and network before ordering

The chassis requires a cabinet deep enough for a 2U server with ready rails installed. Two redundant 1100-watt platinum power supplies need matching PDU outlets. The Intel X520/I350 daughter card delivers two 1 GbE and two 10 Gb SFP+ ports; confirm your top-of-rack switches support the required transceivers. No drives are included, so source compatible SAS or SATA media separately.

Fits high-capacity clusters.

The PERC H730P controller with 2 GB cache manages RAID 0, 1, 5, 6, 10, 50 and 60 directly from the internal bays, leaving PCIe slots open for GPUs or additional NICs. iDRAC 9 Enterprise enables remote firmware updates and power control without a local console. Memory can scale to 3 TB across 24 slots when workloads grow.

Questions about this item

What comes with the R740xd and what must I add before it runs?

The server ships with two Xeon Gold 6148 processors, 64 GB of DDR4 ECC memory, the PERC H730P controller, 24 drive trays, quad-port networking, iDRAC9 Enterprise, dual 1100 W power supplies, rails and bezel. You must supply SAS or SATA drives to fill the 24 bays.

The spec shows 64 GB in a 24-slot chassis — how should I choose the right memory upgrade?

The board has 24 DDR4 slots and supports up to 3 TB. Four slots are already occupied by 16 GB modules at 2666 MHz. Add registered ECC DDR4 in matched sets to keep all channels populated and reach the capacity you need.

The headline says 2.4 GHz — what clock speed will the CPUs actually hold in a 2U rack under load?

Each Xeon Gold 6148 runs at 2.4 GHz base and can turbo to 3.7 GHz depending on core count, temperature and power budget. In a dual-socket 2U with redundant 1100 W supplies the all-core turbo typically settles near the base frequency.
