36-Core Xeon Gold Rack Server

The Dell PowerEdge R640 is a 1U rackmount server built for business workloads such as virtualization, databases, file storage, backups and application hosting. It ships with two Intel Xeon Gold 6154 processors running at 3.00GHz, providing 36 total cores for dependable multi-threaded performance. The system includes 384GB of DDR4 memory and a H730P storage controller. It is suited for organisations needing dense compute in a standard rack footprint.

H730P Controller and 10-Drive Storage

The integrated H730P storage controller manages the ten installed 2TB SATA SSDs, simplifying array configuration and daily administration. The chassis provides ten 2.5-inch drive bays, eight of which are NVMe capable for future high-speed storage upgrades. This combination delivers 20TB of solid-state capacity for operating systems, applications, virtual machines and business data without requiring a separate RAID card purchase.

Dual-Socket Maximum Configuration

The R640 supports a maximum of two processors and this unit already occupies both sockets with Gold 6154 CPUs, so no further CPU expansion is possible. Memory scales to 3TB across the available DIMM slots, leaving headroom beyond the installed 384GB. Buyers who need more than two sockets or GPU acceleration should evaluate alternative platforms.

Questions about this item

When will the 384GB DDR4 memory need to be expanded to the 3TB maximum?

Add modules when virtual machines or databases exceed the installed 384GB DDR4 capacity; the system supports up to 3TB total across all slots.

Which component reaches its limit first during sustained heavy workloads?

The two Xeon Gold 6154 processors with 20 cores each at 3.00GHz set the compute ceiling before the H730P controller or 10 SATA SSDs saturate.

How much heat and power should I plan for when the rack server runs continuously?

The dual 3.00GHz Xeon configuration and 10-drive array draw significant power and produce substantial heat; ensure rack cooling and PDU capacity match the 60 weight specification.
