Two-socket 2U rack server

The Dell PowerEdge R740 is a dual-processor 2U rack server built for compute-intensive workloads. It ships with two Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores and a 3.7 GHz turbo frequency. The system includes 256 GB of DDR4 registered ECC memory across eight 32 GB modules, leaving sixteen slots open for expansion up to the 3 TB maximum.

Redundant 750 W platinum supplies

Dual hot-swap 750 watt platinum-efficiency power supplies provide full redundancy and can be replaced without downtime. The 2U chassis uses front-to-rear airflow across the processor and memory zones, with fan speeds managed by the integrated iDRAC 9 Enterprise controller. Power draw scales with CPU utilisation and the eight installed 10 K RPM SAS drives.

Eight-bay SAS storage and quad-port networking

The front panel holds eight 2.5 inch drive bays populated with 2.4 TB enterprise SAS disks connected to a PERC H730P controller with 2 GB cache and battery backup. RAID levels 0, 1, 5, 6, 10, 50 and 60 are supported alongside pass-through mode. A daughter card adds two 1 GbE ports and two 10 Gb SFP+ ports, while iDRAC 9 Enterprise provides dedicated out-of-band management. Ready rails and a front bezel are included for standard rack mounting.

Questions about this item

How do I install the 2.5" SAS drives into the 8-bay front chassis and which step is commonly missed?

Slide each drive into a bay until the carrier clicks, then verify the PERC H730P BIOS detects all 8 drives before creating RAID volumes.

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

The 2.4TB 10K SAS drives and the PERC H730P controller battery are the primary wear items; the 750W platinum PSUs are hot-swap redundant.

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

The dual 750W platinum power supplies set the sustained power ceiling before the 2U cooling reaches its limit.
