Dell PowerEdge R640 40-Core NVMe Server

The Dell PowerEdge R640 is a 1U rackmount server system built for business workloads including virtualization, databases and application hosting. Two Intel Xeon Gold 6138 processors deliver 40 cores at 2.00GHz for dependable multi-threaded performance. The system ships with 16GB of DDR4 memory and an H730 storage controller.

Ideal for virtualization hosts needing dense NVMe

This server suits IT teams that want to populate ten 2.5-inch bays with up to eight NVMe drives for high-throughput storage layers. Buyers who need GPU acceleration or Fibre Channel connectivity should look at other platforms because this unit relies on integrated graphics and standard Ethernet.

Eight NVMe-capable 2.5-inch drive bays define

The chassis provides ten 2.5-inch expansion bays, eight of which support NVMe protocols for low-latency flash arrays. That bay count and NVMe capability are the primary constraint when sizing databases, virtualisation clusters or backup targets.

Questions about this item

How many 2.5" drive bays are available for future NVMe storage upgrades?

The chassis provides 10 bays, and 8 of them are NVMe capable so you can add high-speed storage later.

What is the maximum DDR4 memory the R640 can accept when the current 16 GB becomes a bottleneck?

The system supports up to 3 TB of DDR4, allowing large capacity upgrades as workloads grow.

How much heat and power should I expect from the dual Xeon Gold 6138 CPUs running continuously?

Two 2.00 GHz 14-core Xeon Gold 6138 processors draw significant power and generate considerable heat under sustained load, so plan for robust rack cooling and adequate PDU capacity.
