DELL PowerEdge R940 3U rack server 4× Xeon Gold 6134 3.2GHz 768GB DDR4 8× 300GB SAS H730P

SKU CH-6HBJ-PXPTP

A 3U rack server with four Xeon Gold 6134 3.2GHz processors, 768GB DDR4 ECC memory, PERC H730P RAID controller, and eight 300GB SAS drives

CPU Model Gold 6134

  • 4× Xeon Gold 6134 3.2 GHz processors deliver 32 total cores for heavy compute workloads
  • 768 GB DDR4 2666 MHz registered ECC memory in 24× 32 GB modules supports large datasets
  • PERC H730P 2 GB controller enables RAID 0/1/5/6/10/50/60 with battery-backed cache
  • 8× 300 GB 10 K SAS drives provide fast 12 Gb/s storage in 2.5" bays
  • iDRAC9 Enterprise and dual 1600 W platinum PSUs give remote management and redundant power

Four-socket 3U server for mission-critical workloads

The Dell PowerEdge R940 fits four Intel Xeon Gold 6134 processors in a 3U rack chassis with redundant 1600 watt power supplies. It targets organisations running databases, virtualisation clusters or analytics that need maximum core density per rack unit. Buyers needing a single-socket tower or a GPU-heavy AI node should look elsewhere.

768 GB DDR4 across 48 slots with room to grow

Installed memory totals 768 GB using 24 modules of 32 GB DDR4 2666 MHz registered ECC, leaving 24 open slots to reach the 6 TB platform maximum. The four LGA 3647 sockets each provide 12 memory channels for balanced bandwidth.

Sustained throughput from eight 10K SAS drives

The PERC H730P controller manages eight 300 GB 10K SAS drives in RAID 0, 1, 5, 6, 10, 50 or 60 with battery-backed cache. Dual 10 Gb SFP+ ports and dual 1 GbE ports on the X520/I350 daughter card maintain network throughput under continuous load, while iDRAC9 Enterprise enables remote monitoring without host OS involvement.

Questions about this item

What does having four 8-core Xeon Gold 6134 CPUs at 3.2 GHz actually deliver in this server?

It provides 32 total cores running at a 3.2 GHz base clock with 3.7 GHz turbo, giving high thread density for virtualisation or database workloads in a single 3U chassis.

The PERC H730P is a 12 Gb/s SAS controller — what does that limit in practice?

The 12 Gb/s SAS interface caps each drive link at that speed, so the eight 300 GB 10 K SAS drives and any additional SAS or SATA devices share the controller's total throughput.

What physical items are included to mount this 3U server in a rack?

Ready Rails and a front bezel are included for installation.
