Four-Socket Xeon Server

The Dell PowerEdge R940 is a 3U rack server built for compute-dense workloads. Four Intel Xeon Gold 6148 processors provide 20 cores each at 2.4 GHz with a 3.7 GHz turbo frequency. The system ships with 512 GB of DDR4 registered ECC memory across 16 modules. It is suited for organisations that need high core counts in a compact rack footprint.

Enterprise Buyers vs Small-Scale Users

This server targets IT departments running virtualisation clusters, in-memory databases or real-time analytics where four-socket scaling matters. The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 2 GB battery-backed cache. Buyers who need only a single or dual-socket platform should consider smaller form factors that cost less to power and cool.

512 GB DDR4 Memory Installed

The chassis holds 48 DIMM slots and supports up to 6 TB of DDR4 when fully populated. The current configuration uses 16 × 32 GB modules running at 2666 MHz. Storage is handled by two 300 GB 10 K SAS drives connected to the H730P controller. Network connectivity includes a quad-port daughter card with two 1 GbE and two 10 Gb SFP+ interfaces. iDRAC 9 Enterprise provides remote management.

Questions about this item

Should I choose the four-processor configuration or a lower-count option?

The system ships with four Intel Xeon Gold 6148 processors, each 20 cores at 2.4 GHz with 3.7 GHz turbo, filling every socket the board supports.

What does 512 GB of DDR4 2666 MHz memory mean for actual workloads?

Sixteen 32 GB registered ECC modules occupy 16 of the 48 slots, leaving room to grow to the 6 TB maximum.

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

The controller caps each SAS lane at 12 Gb/s and supports RAID 0, 1, 5, 6, 10, 50, 60 plus pass-through for the installed 300 GB 10K drives.
