Dense 1U dual-socket platform

The Dell PowerEdge R640 is a 1U rack server built for scale-out workloads. It ships with two Intel Xeon Silver 4116 processors running at 2.1 GHz, each providing 12 cores. The system includes 768 GB of DDR4 registered ECC memory across 24 slots. A PERC H730P controller and eight 2.5-inch drive trays handle local storage.

Suited for virtualisation hosts and database nodes

This configuration fits environments that need high core counts and large memory capacity in a single rack unit. The dual-processor layout and 768 GB installed RAM support dense virtual machine deployments. Buyers who only require a single processor or less memory capacity should consider a smaller system. The eight drive trays limit internal storage to eight 2.5-inch devices.

768 GB DDR4 registered ECC memory installed

The server arrives with 768 GB of DDR4 2400 MHz registered ECC memory, populating all 24 DIMM slots with 32 GB modules. This capacity determines how many virtual machines or how large an in-memory dataset the node can handle immediately. Expansion beyond this figure requires replacing existing modules because no free slots remain.

Questions about this item

What RAID levels does the PERC H730P controller support and what is its maximum SAS throughput?

The PERC H730P supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 12Gb/s SAS interface and includes a 2GB cache battery.

How many 2.5-inch drive trays are included and what drive interfaces do they accept?

Eight 2.5-inch hot-swap trays are supplied and accept both SATA and SAS hard drives or SSDs.

What steps are required to install the server in a rack using the included rails?

Mount the sliding rail assemblies to the front and rear rack posts, then slide the 1U chassis into the rails until it locks; secure the front bezel last.
