Dual-socket Xeon Gold 6148 server

The Dell PowerEdge R740 is a 2U rack server equipped with two 20-core Intel Xeon Gold 6148 processors running at 2.4 GHz with 3.7 GHz turbo. It ships with 256 GB of DDR4 2666 MHz registered ECC memory across 24 slots and a PERC H730P storage controller managing two 400 GB SATA SSDs. iDRAC 9 Enterprise provides out-of-band remote management.

Check chassis depth and network needs

Verify that your rack can accommodate a 2U unit with ready rails and that the front bezel matches your aisle layout. Confirm the X520/I350 daughter card’s two 1 GbE and two 10 Gb SFP+ ports suit your switching infrastructure. Ensure the Intel C620 chipset and LGA 3647 sockets align with any planned processor upgrades within the two-socket maximum.

Sustained load with redundant platinum power

Dual 750 W platinum power supplies share the load and maintain operation if one unit fails. The PERC H730P controller’s 2 GB cache and battery-backed write-back accelerate sustained RAID 0, 1, 5, 6, 10, 50 and 60 workloads. Registered ECC DDR4 memory corrects single-bit errors continuously, protecting data integrity during long compute runs.

Questions about this item

What components come installed and what must be purchased separately?

The server ships with two Xeon Gold 6148 processors, 256 GB DDR4 across eight 32 GB modules, two 400 GB SATA SSDs, a PERC H730P controller with battery, quad-port X520/I350 networking, iDRAC9 Enterprise, dual 750 W power supplies, rails and bezel. Extra drives or memory would be separate purchases.

How do I choose between memory configurations for this R740?

The system has 24 DDR4 slots and currently uses eight 32 GB modules for 256 GB at 2666 MHz. You can add up to 3 TB total using registered ECC DDR4; populate remaining slots in matched sets for best performance.

What does the 2.4 GHz base clock mean in practice on this dual-socket server?

Each Xeon Gold 6148 runs at 2.4 GHz base with 3.7 GHz turbo across 20 cores, giving 40 cores total. The H730P supports RAID 0/1/5/6/10/50/60, and the X520/I350 provides two 1 GbE and two 10 GbE SFP+ ports for high-throughput workloads.
