DELL PowerEdge R640 40-Core Rack Server 2x Xeon Gold 6148 2.40GHz 128GB DDR4 H730P 10x 2TB SATA SSD

Dual-socket Xeon Gold 6148 rack server

This Dell PowerEdge R640 delivers 40 cores across two Intel Xeon Gold 6148 processors running at 2.40GHz. The LGA3647 platform supports up to two CPUs and 3TB of DDR4 memory. It is built for virtualization, databases, file storage and application hosting in a 1U rackmount form factor. Buyers who need GPU-accelerated compute or single-threaded frequency above 3GHz should look elsewhere.

Sustained virtualization and storage throughput

The H730P RAID controller manages ten 2.5-inch drive bays populated with new 2TB SATA SSDs, providing consistent IOPS for mixed read-write workloads. Eight bays are NVMe-capable for future high-speed storage expansion. Integrated graphics and dual 18-core CPUs maintain steady performance under multi-VM loads without thermal throttling in standard rack airflow. The 128GB DDR4 baseline handles moderate memory pressure; larger datasets will require additional DIMMs.

Ten-bay 2.5-inch chassis with NVMe-ready slots

The front panel holds ten hot-swap bays, eight of which accept NVMe U.2 drives alongside SATA SSDs. This density decides whether the server fits your storage topology — fewer bays limit capacity, more bays demand a larger chassis. The 60kg unit requires a four-post rack and adequate front-to-rear cooling. No operating system is included.
