Four-socket Xeon Gold 6148 platform

This 3U rack server delivers four Intel Xeon Gold 6148 processors at 2.40 GHz with 20 cores each and 512 GB of DDR4 2666 MHz registered ECC memory. The Dell PERC H730P controller manages SAS or SATA drives across eight 2.5-inch hot-swap trays. Dual 1600 W platinum power supplies and iDRAC 9 Enterprise remote management come standard. Ready rails and a front bezel are included.

Suits dense virtualisation and database workloads

Organisations that need maximum core count and memory capacity in a 3U footprint will match this configuration. The four-processor limit is already reached, so buyers who require further CPU expansion cannot add sockets. The eight drive trays accept only 2.5-inch SAS or SATA devices; no 3.5-inch bays are present.

PERC H730P RAID controller with 2 GB cache

The storage controller supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Battery-backed cache protects in-flight writes during power loss. All eight bays connect through this single controller, so storage performance scales with the installed drive mix.

Questions about this item

How many processors can this R940 scale to before hitting the socket limit?

The system ships with four Xeon Gold 6148 CPUs installed and the board supports a maximum of four processors, so the socket limit is already reached.

What is the power supply rating and redundancy when the server runs continuously?

Two hot-swap 1600 Watt platinum-efficiency power supplies provide full redundancy for sustained operation.

Which memory generation and form factor must already be on hand to expand the 512 GB installed?

DDR4 registered ECC DIMMs are required; the chassis has 48 slots supporting up to 6 TB total capacity.
