  • 64 GB DDR4 ECC memory installed with 48 slots for expansion
  • PERC H730P controller supports RAID 0/1/5/6/10/50/60 with 2 GB cache
  • Eight 400 GB SATA SSDs provide high-speed storage in eight 2.5-inch bays
  • Dual 1600 W platinum power supplies and iDRAC9 Enterprise ensure resilient remote management

Four-socket Xeon Gold 6142 platform

This Dell PowerEdge R940 packs four Intel Xeon Gold 6142 processors, each running at 2.6 GHz with 16 cores, delivering 64 cores total in a 3U rack chassis. It ships with 64 GB of DDR4 registered ECC memory across 48 slots and eight 400 GB SATA SSDs behind a PERC H730P controller with 2 GB cache. Dual 1600 W platinum power supplies, iDRAC9 Enterprise, and a quad-port 1 GbE plus 10 GbE SFP+ daughter card complete the bundle.

Buyers needing dense multi-threaded compute

The four-socket design suits virtualization hosts, in-memory databases, and high-thread-count workloads that benefit from 64 cores and up to 6 TB of DDR4. Single-threaded tasks or workloads that cannot use many cores will not exploit the hardware, and the 3U height demands a rack with suitable clearance.

PERC H730P RAID flexibility

The installed H730P controller supports RAID 0, 1, 5, 6, 10, 50, 60 and pass-through modes, letting you match redundancy and capacity to the eight 2.5-inch SATA SSD bays.

Questions about this item

Should I choose the 400 GB SATA SSDs or a larger capacity for this R940?

The unit ships with eight 400 GB SATA SSDs on the H730P controller; add larger SATA or SAS drives in the remaining bays if you need more space.

What does the 2.6 GHz Xeon Gold 6142 speed mean for real workloads?

Sixteen cores per processor at 2.6 GHz base and 3.7 GHz turbo give strong multi-thread throughput for databases and virtualisation.

How does the H730P 12 Gb/s SAS/SATA controller limit drive performance?

The H730P caps each SATA SSD at 6 Gb/s while supporting RAID 0/1/5/6/10/50/60 and pass-through for mixed drive sets.
