Four-socket server with 512 GB DDR4

The Dell PowerEdge R940 is a 3U rack server populated with four Intel Xeon Gold 6148 processors, each running at 2.4 GHz with 20 cores. It ships with 512 GB of DDR4 registered ECC memory across 16 modules and a PERC H730P RAID controller managing eight 800 GB SATA SSDs. Dual 1600 W platinum power supplies and iDRAC9 Enterprise provide redundancy and remote management.

Suited for memory-intensive workloads.

This configuration suits organisations running large in-memory databases, virtualisation clusters or analytics workloads that benefit from four sockets and 48 DIMM slots expandable to 6 TB. Buyers who need GPU acceleration or single-threaded frequency above 3.7 GHz turbo should evaluate alternative platforms.

PERC H730P controller with eight SATA SSDs

The integrated PERC H730P 2 GB controller supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode, driving the eight installed 800 GB SATA solid-state drives. This determines the storage performance and redundancy level available without adding a separate controller.

Questions about this item

When will the PERC H730P controller battery need replacement?

The H730P includes a battery-backed cache; under continuous operation the battery typically lasts three to five years before it should be swapped to keep write-back caching safe.

What limits sustained throughput on the storage subsystem first?

Eight 800 GB SATA SSDs on a 12 Gb/s H730P controller will hit the SATA 6 Gb/s link speed before the controller or PCIe bus becomes the bottleneck.

How much power do the dual 1600 W supplies draw at full load?

Each 1600 W Platinum supply can deliver up to its rated output; with four 6148 CPUs and all drives active the system can approach the combined capacity, so plan for adequate PDU headroom.
