A 2U rack server with dual 20-core Xeon Gold 6148 CPUs at 2.4 GHz, 128 GB DDR4 ECC memory, eight 300 GB 10 K SAS drives on a PERC H730P RAID controller, quad-port 1 GbE and 10 Gb SFP+ networking.
The Dell PowerEdge R740 is a 2U rack server 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 system includes 128 GB of DDR4 registered ECC memory across 24 slots, supporting up to 3 TB total capacity.
This configuration fits environments that need high core counts and redundant power in a 2U form factor. Eight 300 GB 10K SAS drives and the PERC H730P controller provide hardware RAID 0, 1, 5, 6, 10, 50 and 60. Buyers who need solid-state storage or more than eight drive bays should evaluate other platforms.
The dual 20-core processors deliver 40 threads total, setting the ceiling for parallel throughput. Memory runs at 2666 MHz DDR4 with ECC protection. Network connectivity includes two 1 GbE and two 10 GbE SFP+ ports via the X520/I350 daughter card. iDRAC 9 Enterprise enables full remote management.

Other versions of this model
This unit ships with two Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores and a 3.7 GHz turbo frequency. The board supports a maximum of two CPUs, so this configuration already reaches the socket limit.
The system includes eight 16 GB DDR4 2666 MHz registered ECC modules, giving 128 GB total across 24 slots. This leaves 16 slots free for expansion up to the 3 TB maximum supported by the C620 chipset.
The H730P provides 2 GB cache and supports RAID 0, 1, 5, 6, 10, 50 and 60. It connects to the eight 300 GB 10K SAS drives at 12 Gb/s, which is the practical throughput ceiling for this storage array.
