PowerEdge R740 2U dual-socket server

The Dell PowerEdge R740 is a 2U rack-mounted server system built for compute-intensive workloads. It ships with two Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores and a 3.7 GHz turbo frequency. The platform includes 768 GB of DDR4 2666 MHz registered ECC memory across 24 slots and a PERC H730P storage controller with 2 GB cache. Eight 400 GB SATA SSDs populate the front 2.5-inch drive bays.

Suited for virtualisation and database clusters

This configuration suits organisations running dense virtualisation, in-memory databases or high-performance computing tasks that benefit from 40 total cores and large memory capacity. The quad-port network daughter card provides two 1 GbE and two 10 Gb SFP+ connections for flexible fabric integration. Buyers who need more than 24 DIMM slots, higher single-thread clock speeds or internal GPU accelerator support should evaluate alternative platforms.

PERC H730P RAID controller with 2 GB cache

The storage subsystem centres on the Dell PERC H730P controller, which supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Its 2 GB battery-backed cache accelerates write-heavy workloads across the eight installed SATA SSDs. The controller uses a 12 Gb/s SAS/SATA interface and manages the 2.5-inch drive bays directly. Confirm that your application’s I/O profile matches this RAID feature set before deployment.

Questions about this item

When will the PERC H730P controller battery need replacement?

The PERC H730P includes a 2GB cache battery that typically lasts several years; the iDRAC 9 Enterprise dashboard will alert you when the battery health drops below the replacement threshold.

Which component hits its limit first during sustained all-core workloads?

The two Xeon Gold 6148 processors run at 2.4 GHz base with a 3.7 GHz turbo ceiling, so the 2.4 GHz all-core frequency is the first hard limit under continuous heavy compute.

How loud and hot does the rack unit get when running 24/7?

Dual 750 W platinum power supplies and redundant hot-swap fans keep the 2U chassis within Dell’s thermal spec; fan speed ramps under load but stays at a level designed for datacentre aisles.
