Dual 18-Core Xeon Gold 6148 Platform

This Dell PowerEdge R640 rackmount server delivers 40 total cores across two Intel Xeon Gold 6148 processors running at 2.40GHz. It targets organisations that run virtualisation clusters, database workloads, or mixed application hosting in a 1U form factor. The 128GB DDR4 memory supports dense virtual machine deployments and memory-intensive business services.

Ten 2.5-Inch Bays With NVMe Capability

The chassis provides ten 2.5-inch drive bays, of which eight accept NVMe devices alongside SATA drives. An H730P storage controller manages the installed 1TB SATA SSDs and handles RAID configuration for operating systems, applications, and backup data. Expansion beyond the ten bays requires external enclosures or a different chassis.

128GB DDR4 Installed With 3TB Maximum

The system ships with 128GB of DDR4 memory installed and supports up to 3TB total capacity across its DIMM slots. Buyers planning large in-memory databases or heavy container workloads must add modules to reach that ceiling. No operating system is included, so licensing and installation remain the customer's responsibility.

Questions about this item

Should I choose a model with 10 SATA SSDs or one with fewer NVMe drives?

This unit ships with 10 new 1TB SATA SSDs in the 2.5-inch bays. Eight of those bays also accept NVMe drives if you need faster flash later.

What does the 40-core total mean for my virtual machines?

Two Xeon Gold 6148 CPUs give 40 cores at 2.40GHz, so you can assign multiple vCPUs to each VM while keeping host overhead low.

How does the H730P controller limit the SSD array?

The H730P manages the 10 SATA SSDs over SATA links, so the array tops out at SATA throughput rather than NVMe speeds.
