DELL PowerEdge R740 2U Server 2x Gold 6142 16C 256GB 2x 2TB 7.2K H740P

Server for virtualised workloads

The Dell EMC PowerEdge R740 is a 2U rack server equipped with two Intel Gold 6142 processors, each offering 16 cores. It ships with 256GB of DDR4 memory and two 2TB 7.2K NL SAS drives managed by an H740P RAID controller. This configuration suits virtualisation hosts, database nodes or compute clusters that demand high core density and redundant power in a compact chassis.

Installation and common issues

The unit includes sliding rails and power cords, so mounting in a standard 19-inch rack is straightforward. Eight 2.5-inch drive bays are populated with the two SAS drives, leaving room for expansion. The iDRAC9 Enterprise module provides remote console and firmware management, reducing the need for physical access. Builders should verify that the H740P firmware is current before creating arrays, as older revisions can misreport drive health on 7.2K SAS media.

Practical limits of SAS and DDR4

The 7.2K SAS interface caps sustained throughput well below flash-based alternatives, so random I/O intensive workloads will see latency limits. DDR4 at 2666 MT/s provides ample bandwidth for the 32 installed modules, but total capacity cannot exceed the 256GB already populated without replacing DIMMs. PCIe Gen 3 slots top out at eight lanes per device, restricting the peak bandwidth available to add-in accelerators or additional storage controllers.
