Dual-socket 2U rack server for compute-intensive

The Dell PowerEdge R740 fits a standard 2U rack space and delivers two Intel Xeon Gold 6148 processors, each with 20 cores at 2.40 GHz and a 3.7 GHz turbo frequency. With 256 GB of DDR4 2666 MHz registered ECC memory installed across eight 32 GB modules, the system targets virtualisation, database and high-performance computing tasks that demand high core counts and large memory capacity.

SAS/SATA storage controller and networking limits

The integrated PERC H730P controller provides 2 GB cache and supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode over a 12 Gb/s SAS/SATA interface. The eight 2.5-inch drive bays currently hold two 300 GB 10K SAS drives, leaving six bays open for additional SAS or SATA devices. Network connectivity comes from an Intel X520/I350 daughter card offering two 1 GbE ports and two 10 Gb SFP+ ports.

Verify rack depth, power

The chassis uses redundant 750 W platinum power supplies and includes sliding rails and a front bezel; confirm your rack depth and available PDU outlets match the unit's requirements. Memory can scale to 3 TB across 24 DDR4 slots, so plan future upgrades using registered ECC DDR4 2666 MHz modules only. Remote management is handled by iDRAC9 Enterprise, which requires a dedicated network connection for out-of-band access.

Perguntas sobre este artigo

Should I pick the 256 GB DDR4 configuration or add more modules later?

The system ships with 256 GB across eight 32 GB DDR4 2666 MHz registered ECC modules, leaving sixteen of the twenty-four slots free for future expansion up to 3 TB.

What does the 2.4 GHz base clock with 3.7 GHz turbo mean for real workloads?

Each Xeon Gold 6148 runs at 2.4 GHz base and can boost to 3.7 GHz, giving two 20-core processors strong single-thread response and high multi-thread throughput for virtualization and databases.

How does the PERC H730P 12 Gb/s SAS controller limit drive performance?

The H730P supports 12 Gb/s SAS and SATA with RAID 0, 1, 5, 6, 10, 50, 60 and pass-through, so the installed 300 GB 10K SAS drives and any future SAS or SATA drives run at full interface speed.
