CPU Model Gold 5118

  • Four-socket Xeon Gold 5118 delivers 48 cores for heavy workloads
  • 256 GB DDR4 ECC memory supports large in-memory datasets
  • PERC H730P RAID controller enables multiple redundancy levels
  • Eight 400 GB SATA SSDs provide fast read-intensive storage
  • Dual 1600 W platinum PSUs with iDRAC9 Enterprise ensure uptime

Mission-critical compute density

The Dell PowerEdge R940 packs four Intel Xeon Gold 5118 processors into a 3U rack chassis, delivering 48 cores at 2.3 GHz with 3.2 GHz turbo for heavy database and virtualisation workloads. It ships with 256 GB of DDR4 registered ECC memory across 48 slots and includes iDRAC 9 Enterprise for remote management.

Maximum processor count is the gating factor

The system supports four sockets and arrives fully populated with four 12-core CPUs, so no further processor upgrades are possible; expansion is limited to memory and storage within the existing 48 DIMM slots and eight drive bays.

Dual 1600 W platinum supplies share load

Redundant hot-swap power supplies run at platinum efficiency, keeping thermals stable under full CPU utilisation while fan noise remains typical for a densely packed 3U server in a cooled rack environment.

Questions about this item

What does having four 12-core Xeon Gold 5118 processors at 2.3 GHz mean for real-world throughput?

The server delivers 48 physical cores at a 2.3 GHz base frequency with 3.2 GHz turbo, giving high parallel capacity for virtualisation, databases and compute-intensive workloads.

What does the PERC H730P controller's 12 Gb/s SAS/SATA interface cap in practice?

The H730P runs the eight 400 GB SATA SSDs at up to 6 Gb/s each and supports RAID 0, 1, 5, 6, 10, 50 and 60 with its 2 GB cache and battery backup.

What physical space and mounting hardware does the 3U chassis need?

The 3U rack-mount chassis includes ready rails and a front bezel for standard 4-post cabinet installation and uses two redundant 1600 W platinum power supplies.
