CPU Model Gold 6130

  • Four-socket Xeon Gold 6130 delivers 64 cores at 2.1 GHz base
  • 64 GB DDR4 2666 MHz ECC memory with 48 slots for expansion
  • PERC H730P 2 GB cache enables RAID 0/1/5/6/10/50/60
  • Eight 300 GB 10K SAS drives provide fast 2.5-inch storage
  • Dual 1600 W platinum PSUs plus iDRAC9 Enterprise ensure uptime

Processor Configuration

The Dell PowerEdge R940 is a 3U rack server fitted with four Intel Xeon Gold 6130 processors, each running at 2.1 GHz with 16 cores. The system ships with 64 GB of DDR4 registered ECC memory across 48 slots and includes a PERC H730P controller managing eight 300 GB 10K SAS drives. Redundant 1600 W power supplies and iDRAC9 Enterprise remote management complete the package. It targets organisations running memory-intensive databases or virtualisation clusters that need four-socket density in a compact chassis.

Suitability

This server suits IT teams that require maximum core count and memory capacity within a 3U footprint and can work with the installed 300 GB SAS drives. The eight 2.5-inch bays limit raw capacity, so buyers who need larger drive counts or higher single-thread frequencies should consider alternative configurations. The quad-port 1 GbE and 10 Gb SFP+ networking covers typical data-centre connectivity without additional cards.

Decisive Specification

The four-socket LGA 3647 design with 48 DDR4 slots supporting up to 6 TB of memory is the specification that determines fit. Workloads that scale across 64 cores and terabytes of RAM will use the platform fully; lighter workloads leave much of the hardware idle.

Questions about this item

How do I install the 2.5" SAS drives into the 8-bay front panel and which step is most often missed?

Slide each 300GB 10K SAS drive into a front bay until the lever clicks, then use the PERC H730P BIOS utility to create a virtual disk; the step most often missed is initializing the array before the OS install.

What maintenance will the PERC H730P controller battery need and when?

The H730P includes a 2GB cache battery that typically lasts three to five years; replace it when iDRAC 9 Enterprise reports a battery-learn failure or degraded write-back cache.

What thermal limit appears first when all four Xeon Gold 6130 CPUs run at 3.7GHz turbo continuously?

The 1600W platinum power supplies hit their current ceiling before the heatsinks saturate, so sustained 3.7GHz turbo on all 64 cores will throttle at the PSU limit.
