Dual 20-core Xeon 2U server

The Dell PowerEdge R740 is a 2U rack server populated with two Intel Xeon Gold 6148 processors, each running 20 cores at 2.4 GHz. It ships with 64 GB of DDR4 memory across 24 slots and a PERC H730P controller managing eight 300 GB 10K SAS drives. Redundant 750 W power supplies and iDRAC 9 Enterprise complete the platform.

Suited for multi-threaded workloads

This configuration fits virtualisation hosts, database nodes or compute clusters that benefit from 40 total cores and hardware RAID. Buyers who need more installed memory than 64 GB or additional drive bays beyond the eight 2.5-inch slots should consider a different chassis.

PERC H730P with 2 GB cache

The storage controller supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Its 2 GB battery-backed cache determines the write performance and data protection level for the eight SAS drives.

Questions about this item

What does the 3.7 GHz turbo frequency mean for workloads running on the two 20-core Xeon Gold 6148 processors?

The 3.7 GHz turbo allows each of the 40 total cores to boost above the 2.4 GHz base when thermal headroom exists, giving short bursts of higher single-thread speed for latency-sensitive tasks.

What practical throughput does the PERC H730P 12 Gb/s SAS controller deliver to the eight 300 GB 10K drives?

The controller supports 12 Gb/s SAS lanes and RAID 0/1/5/6/10/50/60; real-world throughput is limited by the 10K spindle speed and the 2 GB cache buffer on the card.

How much additional DDR4 registered ECC memory can be installed in the remaining DIMM slots?

Four 16 GB modules occupy 4 of the 24 slots, leaving 20 slots open to reach the 3 TB maximum with compatible DDR4 2666 MHz registered ECC DIMMs.
