Dense 1U compute platform

This Dell PowerEdge R640 is a 1U rack server fitted with two Intel Xeon Gold 6142 processors. Each CPU runs at 2.6 GHz with 16 cores, delivering 32 cores in total. The system ships with 768 GB of DDR4 2666 MHz registered ECC memory across 24 DIMM slots. It targets organisations that need high core density in a single rack unit for virtualisation, database or high-performance computing workloads.

Suited for scale-out workloads.

The eight 2.5-inch drive bays hold 600 GB 10K SAS drives managed by a PERC H730P controller with 2 GB cache. Network connectivity comes from an Intel X520/I350 daughter card providing two 1 GbE and two 10 GbE SFP+ ports. Remote management uses iDRAC 9 Enterprise. Builders who need internal GPU acceleration or more than eight drive bays should consider a larger chassis.

Dual-socket 16-core limit defines capacity

Both LGA 3647 sockets are populated, so the server cannot accept additional processors. The Intel C620 chipset supports up to 3 TB of DDR4, leaving headroom for memory expansion. Redundant 750 W platinum power supplies and sliding rails are included for immediate rack deployment.

Questions about this item

Should I choose the 768GB configuration or plan for the 3TB maximum?

The server ships with 768GB across 24 slots using 32GB DDR4 2666MHz registered ECC modules. The 3TB maximum is the platform limit with larger DIMMs.

What does the 2.6GHz base and 3.7GHz turbo mean for real workloads?

Two Xeon Gold 6142 processors provide 32 cores at 2.6GHz base, with turbo up to 3.7GHz for burst performance on demanding applications.

How does the H730P 12Gb/s SAS controller limit the 8x 600GB 10K drives?

The PERC H730P 2GB controller runs the SAS drives at 12Gb/s and supports RAID 0, 1, 5, 6, 10, 50, 60 plus pass-through mode.
