Dual 20-core Xeon Gold 6148 platform

This 1U rack server ships with two Intel Xeon Gold 6148 processors at 2.4 GHz, each providing 20 cores for a total of 40 threads. The system includes 128 GB of registered ECC DDR4 memory across eight 16 GB modules running at 2666 MHz. It is built for dense scale-out workloads in a compact form factor.

Suited for virtualisation and database clusters

The dual-socket configuration and high core count serve environments that run multiple virtual machines or memory-intensive databases. Buyers who need GPU acceleration, larger local storage arrays, or single-thread optimisation should evaluate alternative platforms. The 1U height limits expansion card space compared with taller chassis.

H730P RAID with dual 400 GB SSDs

A Dell PERC H730P controller with 2 GB cache manages the two installed 400 GB SATA SSDs and supports RAID levels 0, 1, 5, 6, 10, 50 and 60. Quad-port networking provides two 1 GbE and two 10 Gb SFP+ connections via an Intel X520/I350 daughter card. Redundant 750 W platinum power supplies and iDRAC9 Enterprise remote management complete the infrastructure-ready package.

Questions about this item

Does the Dell PowerEdge R640 ship with rails for rack mounting?

The system includes Ready Rails and a front bezel for rack installation.

Can the installed Xeon Gold 6148 processors run alongside older Xeon CPUs in the same chassis?

The board uses LGA 3647 sockets and the Intel C620 chipset, which are specific to this generation of Xeon Scalable processors.

How do I confirm the PERC H730P controller is managing the two 400GB SSDs correctly after setup?

Check the controller BIOS or iDRAC 9 Enterprise storage view for RAID status, drive health and the configured RAID level.
