Dual-socket 2U rack server

The Dell PowerEdge R740 is a 2U rack server fitted with two Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores. It ships with 768 GB of DDR4 registered ECC memory across 24 slots and eight 2.4 TB 10K SAS hard drives on a PERC H730P controller. Dual 750 W platinum power supplies and iDRAC9 Enterprise remote management are included.

Virtualisation hosts and database clusters.

This configuration suits virtualisation hosts, database clusters and high-thread-count workloads that benefit from 40 total cores and a large memory footprint. The eight 2.5-inch SAS bays and quad-port 1 GbE and 10 Gb SFP+ networking support dense storage and fast fabric connectivity. Buyers who need more than two sockets, front-access U.2 bays, internal GPU power cables or more than eight drive bays should look at a different platform.

768 GB DDR4 registered ECC across 24 slots

The installed 768 GB of DDR4 registered ECC memory fills all 24 DIMM slots, leaving no room for expansion without removing modules. Maximum supported capacity is 3 TB, but reaching it requires replacing the existing 32 GB sticks. Verify that your workload fits within 768 GB or plan for a memory swap before deployment.

Questions about this item

What infrastructure is required to install the 2U rack chassis?

The server fits a standard 2U rack space and includes ready rails with a front bezel for mounting.

Can the existing 2.4TB 10K SAS drives remain in use if I add more storage later?

Yes, the PERC H730P controller supports SAS and SATA drives together in the same 8-bay backplane.

How do I confirm the dual Xeon Gold 6148 processors and 768GB DDR4 are recognised at boot?

iDRAC9 Enterprise shows both 20-core CPUs and all 24 memory modules during POST and in the system inventory.
