Dense 1U dual-socket compute node

The Dell PowerEdge R640 is a 1U rack server built around two Intel Xeon Silver 4116 processors running at 2.1 GHz with 12 cores each. It ships with 768 GB of DDR4 registered ECC memory across 24 slots and a PERC H730P controller driving eight 300 GB 10K SAS drives. Dual 750 W platinum power supplies and iDRAC9 Enterprise remote management come standard.

Scale-out workloads needing memory capacity

This configuration suits virtualisation clusters, database nodes or HPC front-ends that benefit from 24 cores and a large DDR4 footprint in a single rack unit. The eight-bay 2.5-inch chassis and redundant power support high availability requirements. Buyers who need GPU acceleration, all-flash arrays or single-thread frequency above 3.0 GHz should evaluate alternative platforms.

24 DIMM slots supporting up to 3 TB DDR4

The server provides 24 memory slots populated with 24 x 32 GB modules today and can scale to 3 TB total capacity. This headroom determines whether the chassis can grow with future workload demands without replacing the platform.

Questions about this item

Should I pick the 300 GB 10K SAS drives or add larger capacity drives?

The 8 installed 300 GB 10K SAS drives deliver fast spindle speed for transactional workloads; the PERC H730P supports larger SAS or SATA drives if you need more raw capacity.

What does the 2.1 GHz base clock with 3.0 GHz turbo mean for actual throughput?

Each of the 24 cores runs at 2.1 GHz base and can boost to 3.0 GHz under load, giving strong single-thread response while maintaining all-core performance for virtualization or databases.

How does the 12 Gb/s SAS controller limit real-world drive speed?

The H730P’s 12 Gb/s SAS lanes match the 12 Gb/s rating of the installed drives, so the controller does not bottleneck sequential or random I/O from the 10K disks.
