Dell PowerEdge R740 2U Rack Server

The Dell PowerEdge R740 is a 2U rack server designed for high-performance computing environments. It features dual Intel Xeon Gold 6142 processors running at 2.6 GHz with 16 cores each. The system includes 512 GB of DDR4 memory and eight 800 GB SATA SSDs managed by a PERC H730P controller.

Suited for virtualisation and database workloads

This server suits organisations running virtualised workloads, databases or applications that benefit from high core counts and large memory capacity. The redundant 750 W power supplies and iDRAC9 Enterprise remote management support continuous operation. Buyers who need more than 24 memory slots or require a different storage interface should evaluate other platforms.

512 GB DDR4 registered ECC memory installed

The single specification that decides fit is the 512 GB of DDR4 2666 MHz registered ECC memory populated across 16 modules. This configuration determines immediate capacity for memory-intensive tasks and leaves eight of the 24 slots available for future expansion up to the 3 TB maximum.

Questions about this item

Will the 2.6 GHz Xeon Gold 6142 CPUs throttle under continuous all-core load?

The two Xeon Gold 6142 processors run at a 2.6 GHz base frequency with a 3.7 GHz turbo limit; sustained all-core work will sit at or near the base clock once thermal limits are reached.

How much heat and fan noise should I expect from the dual 750 W power supplies and CPUs running 24/7?

Dual 750 W platinum supplies and two 16-core CPUs will draw significant power continuously, so the chassis fans ramp up to maintain thermal limits, producing noticeable rack-level noise.

Which cables or modules do I need to use the two 10 Gb SFP+ ports on the X520/I350 daughter card?

The X520/I350 card provides two 10 Gb SFP+ ports; you must supply compatible SFP+ transceivers and fibre or direct-attach cables, as none are included with the server.
