Dell PowerEdge R740 2U rack server

The Dell PowerEdge R740 is a 2U rack server built around two Intel Xeon Gold 6142 processors running at 2.6GHz with 16 cores each. It ships with 768GB of DDR4 2666MHz registered ECC memory across 24 slots and a Dell PERC H730P 2GB storage controller supporting RAID 0, 1, 5, 6, 10, 50 and 60. Two 400GB SATA SSDs are installed in the eight 2.5-inch drive bays.

Who this suits and who should look elsewhere

This server suits organisations that need high CPU core counts and large memory capacity for virtualisation, database or compute workloads in a 2U form factor. The quad-port network daughter card provides two 1GbE and two 10Gb SFP+ connections for flexible networking. Buyers who require more than eight 2.5-inch drive bays or a different drive interface should evaluate other platforms, as this unit is limited to the installed SATA/SAS backplane.

Specification that decides fit

The critical specification is the dual Xeon Gold 6142 configuration delivering 32 total cores at 2.6GHz base frequency with 3.7GHz turbo, combined with 768GB of DDR4 memory and the PERC H730P controller. This specific processor, memory and storage controller combination determines whether the server matches the performance and redundancy requirements of the target workload.

Points forts

Questions sur cet article

How do I install the 2.5-inch SSDs into the eight-bay front chassis, and what step is often missed?

Slide each drive into a bay until the carrier clicks, then verify the PERC H730P controller sees both 400GB SSDs in the BIOS before creating a virtual disk.

Which components will need replacement first during long-term operation?

The PERC H730P RAID battery and the two 750W power supplies are the field-replaceable parts most likely to require service after several years.

What thermal or power limit appears first when both Xeon Gold 6142 CPUs run at 3.7GHz turbo under sustained load?

The dual 750W platinum power supplies set the ceiling; if combined draw exceeds their rated output the system will throttle before temperatures reach critical levels.
