2U 26-bay storage server

The Dell PowerEdge R740xd2 is a 2U rack server built for high-capacity storage deployments. It ships with two Intel Xeon Gold 6154 processors running at 3.0 GHz with 18 cores each and 256 GB of DDR4-2666 ECC registered memory. The Dell PERC H730P controller provides 2 GB cache and supports RAID 0, 1, 5, 6, 10, 50 and 60. Twenty-six 3.5-inch drive trays, dual 10/25 Gb SFP28 ports, dual 1 GbE LOM and iDRAC 9 Enterprise complete the platform.

Suited for dense backup and software-defined storage

This server targets organisations that need maximum 3.5-inch drive density in a 2U footprint for backup repositories, media archives or software-defined storage clusters. The 26 hot-swap trays and 12 Gb/s SAS/SATA controller support large-capacity hard drives and SSDs. Buyers who require 2.5-inch drive bays, front bezel or ready rails included, or a single-processor configuration should look at other platforms.

26 x 3.5-inch tray capacity decides fit

The defining specification is the 26-bay 3.5-inch chassis, which sets the raw storage ceiling for the system. With dual Xeon Gold 6154 CPUs, 256 GB DDR4 and the H730P controller already installed, the server is ready for high-throughput RAID arrays once drives are added. Dual 1100 W platinum power supplies and iDRAC 9 Enterprise provide redundancy and remote management for continuous operation.

Questions about this item

Should I choose the 256 GB DDR4 configuration or add more memory later?

The server arrives with 256 GB across 8 of 16 slots, so 8 slots remain free for expansion up to the 1 TB maximum.

What does the 3.0 GHz base clock with 3.7 GHz turbo mean for sustained workloads?

Each of the 18 cores runs at 3.0 GHz continuously and can boost to 3.7 GHz when thermal headroom allows, giving strong single-thread bursts for database or analytics tasks.

Does the PERC H730P controller limit drive throughput on the 26 bays?

The H730P provides 12 Gb/s SAS/SATA connectivity, so each bay can reach full 12 Gb/s speeds with compatible drives; the controller supports RAID 0/1/5/6/10/50/60 and pass-through modes.
